/* This file contains subroutines used only from the file reload1.c.
It knows how to scan one insn for operands and values
that need to be copied into registers to make valid code.
It also finds other operands and values which are valid
but for which equivalent values in registers exist and
ought to be used instead.
Before processing the first insn of the function, call `init_reload'.

init_reload actually has to be called earlier anyway.

To scan an insn, call `find_reloads'. This does two things:
1. sets up tables describing which values must be reloaded
for this insn, and what kind of hard regs they must be reloaded into;
2. optionally record the locations where those values appear in
the data, so they can be replaced properly later.
This is done only if the second arg to `find_reloads' is nonzero.
The third arg to `find_reloads' specifies the number of levels
of indirect addressing supported by the machine. If it is zero,
indirect addressing is not valid. If it is one, (MEM (REG n))
is valid even if (REG n) did not get a hard register; if it is two,
(MEM (MEM (REG n))) is also valid even if (REG n) did not get a
hard register, and similarly for higher values.
Then you must choose the hard regs to reload those pseudo regs into,
and generate appropriate load insns before this insn and perhaps
also store insns after this insn. Set up the array `reload_reg_rtx'
to contain the REG rtx's for the registers you used. In some
cases `find_reloads' will return a nonzero value in `reload_reg_rtx'
for certain reloads. Then that tells you which register to use,
so you do not need to allocate one. But you still do need to add extra
instructions to copy the value into and out of that register.
Finally you must call `subst_reloads' to substitute the reload reg rtx's
into the locations already recorded.
NOTE SIDE EFFECTS:
find_reloads can alter the operands of the instruction it is called on.
1. Two operands of any sort may be interchanged, if they are in a
commutative instruction.
This happens only if find_reloads thinks the instruction will compile
better that way.
2. Pseudo-registers that are equivalent to constants are replaced
with those constants if they are not in hard registers.
1 happens every time find_reloads is called.
2 happens only when REPLACE is 1, which is only when
actually doing the reloads, not when just counting them.
Using a reload register for several reloads in one insn:
When an insn has reloads, it is considered as having three parts:
the input reloads, the insn itself after reloading, and the output reloads.
Reloads of values used in memory addresses are often needed for only one part.
When this is so, reload_when_needed records which part needs the reload.
Two reloads for different parts of the insn can share the same reload
register.
When a reload is used for addresses in multiple parts, or when it is
an ordinary operand, it is classified as RELOAD_OTHER, and cannot share
a register with any other reload. */

/* Return nonzero if IN can be reloaded into REGNO with mode MODE without
requiring an extra reload register. The caller has already found that
IN contains some reference to REGNO, so check that we can produce the
new value in a single step. E.g. if we have
(set (reg r13) (plus (reg r13) (const int 1))), and there is an
instruction that adds one to a register, this should succeed.
However, if we have something like
(set (reg r13) (plus (reg r13) (const int 999))), and the constant 999
needs to be loaded into a register first, we need a separate reload
register.
Such PLUS reloads are generated by find_reload_address_part.
The out-of-range PLUS expressions are usually introduced in the instruction
patterns by register elimination and substituting pseudos without a home
by their function-invariant equivalences. */

IN is an rtx saying where the data are to be found before this instruction.
OUT says where they must be stored after the instruction.
(IN is zero for data not read, and OUT is zero for data not written.)
INLOC and OUTLOC point to the places in the instructions where
IN and OUT were found.

CLASS is a register class required for the reloaded data.
INMODE is the machine mode that the instruction requires
for the reg that replaces IN and OUTMODE is likewise for OUT.
If IN is zero, then OUT's location and mode should be passed as
INLOC and INMODE.
STRICT_LOW is the 1 if there is a containing STRICT_LOW_PART rtx.
OPTIONAL nonzero means this reload does not need to be performed:
it can be discarded if that is more convenient.

The return value is the reload-number for this reload.
If both IN and OUT are nonzero, in some rare cases we might
want to make two separate reloads. (Actually we never do this now.)
Therefore, the reload-number for OUT is stored in
output_reloadnum when we return; the return value applies to IN.
Usually (presently always), when IN and OUT are nonzero,
the two reload-numbers are equal, but the caller should be careful to
distinguish them. */

Fix consistency problems with reg_equiv_{mem,address}; Improve reload inheritance; * reload.c (reload_out_reg): New variable. (loc_mentioned_in_p, remove_address_replacements): New functions. (remove_replacements): Deleted. (push_reload): Set reload_out_reg[i]. When merging, also set reload_{in,out}_reg[i], and remove duplicate address reloads. (combine_reloads): Copy reload_out_reg[i]. (find_reloads): Do make_memloc substitution also when reg_equiv_memory_loc[regno] and num_not_at_initial_offset are both nonzero. Include *recog_operand_loc in commutativity operand changes. Generate optional output reloads. Delete reference to n_memlocs. Don't set *recog_operand_loc before processing operands. Call make_memloc in reg_equiv_address code. Set *recog_operand_loc only after processing operands, and only if replace is true. Return a value. When changing address reload types for operands that didn't get reloaded, use RELOAD_FOR_OPADDR_ADDRESS for RELOAD_FOR_INPADDR_ADDRESS / RELOAD_FOR_OUTADDR_ADDRESS reloads. Don't emit USEs for pseudo SUBREGs when not replacing. (find_reloads_address): Do make_memloc substitution also when reg_equiv_memory_loc[regno] and num_not_at_initial_offset are both nonzero. (find_reloads_toplev): Likewise. Call make_memloc in reg_equiv_address code. (debug_reload_to_stream): Add code to output reload_out_reg. (make_memloc): Delete local variable i, ifdefed out code, and references to memlocs and n_memlocs. (memlocs, n_memlocs): Delete. (push_secondary_reload): Clear reload_out_reg. (find_reloads_address_1): Provide memrefloc argument to all calls to find_reloads_address. In AUTO_INC code, handle non-directly addressable equivalences properly. * reload.h (reload_out_reg, num_not_at_initial_offset): Declare. (find_reloads): Add return type. (remove_address_replacements, deallocate_reload_reg): Declare. * reload1.c (num_not_at_initial_offset): No longer static. (delete_address_reloads, delete_address_reloads_1): Likewise. (deallocate_reload_reg): New function. (spill_reg_stored_to): New array. (eliminate_regs): Don't substitute from reg_equiv_memory_loc. (eliminate_regs_in_insn): Move assignments of previous_offset and max_offset fields, and recalculation of num_not_at_initial_offset into new static function: (update_eliminable_offsets) . (reload_as_needed): Call update_eliminable_offsetss after calling find_reloads. Call forget_old_reloads_1 with contents of reloaded auto_inc expressions if the actual addressing can't be changed to match the auto_inc. (choose_reload_regs): For inheritance, replace reload_reg_free_before_p test with reload_reg_ions. (emit_reload_insns): If reload_in is a MEM, set OLD to reload_in_reg[j]. Don't reload directly from oldequiv; if it's a pseudo with a stack slot, use reload_in[j]. Check that reload_in_reg[j] is a MEM before replacing reload_in from reg_reloaded_contents. Include non-spill registers in reload inheritance processing. Also try to use reload_out_reg to set spill_reg_store / reg_last_reload_reg. In code to set new_spill_reg_store, use single_set to find out if there is a single set. Add code that allows to delete optional output reloads. Add code to allow deletion of output reloads that use no spill reg. At the end, set reload_override_in to oldequiv. Also call delete_output_reload if reload_out_reg is equal to old in oldequiv code. Add code to call delete_output_reload for stores with no matching load. Set / use spill_reg_stored_to. Handle case where secondary output reload uses a temporary, but actual store isn't found. When looking for a store of a value not loaded in order to call delete_output_reload, count_occurences should return 0 for no loads; but discount inherited input reloadill_reg_stored_to. Do checks for extra uses of REG. Changed all callers. Use delete_address_reloads. (reload): Take return value of find_reloads into account. If a no-op set needs more than one reload, delete it. (reload_reg_free_before_p): RELOAD_FOR_INPUT can ignore RELOAD_FOR_INPUT_ADDRESS / RELOAD_FOR_INPADDR_ADDRESS for the same operand. (clear_reload_reg_in_use): Check for other reloads that keep a register in use. (reload_reg_free_for_value_p): handle RELOAD_FOR_OPERAND_ADDRESS / RELOAD_FOR_OPADDR_ADDR. Take into account when an address address reload is only needed for the address reload we are considering. (count_occurrences): Use rtx_equal_p for MEMs. (inc_for_reload): Return instruction that stores into RELOADREG. New argument two, IN, and rtx. Changed all callers. (calculate_needs_all_insns, reload_as_needed): Don't clear after_call for a CLOBBER. Keep track of how many hard registers need to be copied from after_call, and don't clear after_call before we have seen that much copies, or we see a different instruction. From-SVN: r23143

Do checks for extra uses of REG. Changed all callers. Use delete_address_reloads. (reload): Take return value of find_reloads into account. If a no-op set needs more than one reload, delete it. (reload_reg_free_before_p): RELOAD_FOR_INPUT can ignore RELOAD_FOR_INPUT_ADDRESS / RELOAD_FOR_INPADDR_ADDRESS for the same operand. (clear_reload_reg_in_use): Check for other reloads that keep a register in use. (reload_reg_free_for_value_p): handle RELOAD_FOR_OPERAND_ADDRESS / RELOAD_FOR_OPADDR_ADDR. Take into account when an address address reload is only needed for the address reload we are considering. (count_occurrences): Use rtx_equal_p for MEMs. (inc_for_reload): Return instruction that stores into RELOADREG. New argument two, IN, and rtx. Changed all callers. (calculate_needs_all_insns, reload_as_needed): Don't clear after_call for a CLOBBER. Keep track of how many hard registers need to be copied from after_call, and don't clear after_call before we have seen that much copies, or we see a different instruction. From-SVN: r23143

/* If this is an input reload and the operand contains a register that
dies in this insn and is used nowhere else, see if it is the right class
to be used for this reload. Use it if so. (This occurs most commonly
in the case of paradoxical SUBREGs and in-out reloads). We cannot do
this if it is also an output reload that mentions the register unless
the output is a SUBREG that clobbers an entire register.
Note that the operand might be one of the spill regs, if it is a
pseudo reg and we are in a block where spilling has not taken place.
But if there is no spilling in this block, that is OK.
An explicitly used hard reg cannot be a spill reg. */

(get_secondary_mem): Accept and use reload description (opnum and type). (push_reload): Accept and use new reload description instead of old NEEDED_FOR. Define two new macros: MERGEABLE_RELOADS and MERGE_TO_OTHER. Use these macros to see if reloads can be merged and how to do it. (transfer_replacements): New function. (combine_reloads): Refine when we can combine reloads. (find_reloads): Use new method of tracking what a reload is for. When we make a CLOBBER insn, do so with DImode. Merge cases of making optional reloads, avoid making output-only optional reloads, refine when we may not make in-out optional reloads, and make an optional reload for a pair of matching operands. (find_reloads_toplev, find_reloads_address{,_1, part}): Accept and use reload description. (forget_volatility): Delete long-obsolete function. From-SVN: r3911

Fix consistency problems with reg_equiv_{mem,address}; Improve reload inheritance; * reload.c (reload_out_reg): New variable. (loc_mentioned_in_p, remove_address_replacements): New functions. (remove_replacements): Deleted. (push_reload): Set reload_out_reg[i]. When merging, also set reload_{in,out}_reg[i], and remove duplicate address reloads. (combine_reloads): Copy reload_out_reg[i]. (find_reloads): Do make_memloc substitution also when reg_equiv_memory_loc[regno] and num_not_at_initial_offset are both nonzero. Include *recog_operand_loc in commutativity operand changes. Generate optional output reloads. Delete reference to n_memlocs. Don't set *recog_operand_loc before processing operands. Call make_memloc in reg_equiv_address code. Set *recog_operand_loc only after processing operands, and only if replace is true. Return a value. When changing address reload types for operands that didn't get reloaded, use RELOAD_FOR_OPADDR_ADDRESS for RELOAD_FOR_INPADDR_ADDRESS / RELOAD_FOR_OUTADDR_ADDRESS reloads. Don't emit USEs for pseudo SUBREGs when not replacing. (find_reloads_address): Do make_memloc substitution also when reg_equiv_memory_loc[regno] and num_not_at_initial_offset are both nonzero. (find_reloads_toplev): Likewise. Call make_memloc in reg_equiv_address code. (debug_reload_to_stream): Add code to output reload_out_reg. (make_memloc): Delete local variable i, ifdefed out code, and references to memlocs and n_memlocs. (memlocs, n_memlocs): Delete. (push_secondary_reload): Clear reload_out_reg. (find_reloads_address_1): Provide memrefloc argument to all calls to find_reloads_address. In AUTO_INC code, handle non-directly addressable equivalences properly. * reload.h (reload_out_reg, num_not_at_initial_offset): Declare. (find_reloads): Add return type. (remove_address_replacements, deallocate_reload_reg): Declare. * reload1.c (num_not_at_initial_offset): No longer static. (delete_address_reloads, delete_address_reloads_1): Likewise. (deallocate_reload_reg): New function. (spill_reg_stored_to): New array. (eliminate_regs): Don't substitute from reg_equiv_memory_loc. (eliminate_regs_in_insn): Move assignments of previous_offset and max_offset fields, and recalculation of num_not_at_initial_offset into new static function: (update_eliminable_offsets) . (reload_as_needed): Call update_eliminable_offsetss after calling find_reloads. Call forget_old_reloads_1 with contents of reloaded auto_inc expressions if the actual addressing can't be changed to match the auto_inc. (choose_reload_regs): For inheritance, replace reload_reg_free_before_p test with reload_reg_ions. (emit_reload_insns): If reload_in is a MEM, set OLD to reload_in_reg[j]. Don't reload directly from oldequiv; if it's a pseudo with a stack slot, use reload_in[j]. Check that reload_in_reg[j] is a MEM before replacing reload_in from reg_reloaded_contents. Include non-spill registers in reload inheritance processing. Also try to use reload_out_reg to set spill_reg_store / reg_last_reload_reg. In code to set new_spill_reg_store, use single_set to find out if there is a single set. Add code that allows to delete optional output reloads. Add code to allow deletion of output reloads that use no spill reg. At the end, set reload_override_in to oldequiv. Also call delete_output_reload if reload_out_reg is equal to old in oldequiv code. Add code to call delete_output_reload for stores with no matching load. Set / use spill_reg_stored_to. Handle case where secondary output reload uses a temporary, but actual store isn't found. When looking for a store of a value not loaded in order to call delete_output_reload, count_occurences should return 0 for no loads; but discount inherited input reloadill_reg_stored_to. Do checks for extra uses of REG. Changed all callers. Use delete_address_reloads. (reload): Take return value of find_reloads into account. If a no-op set needs more than one reload, delete it. (reload_reg_free_before_p): RELOAD_FOR_INPUT can ignore RELOAD_FOR_INPUT_ADDRESS / RELOAD_FOR_INPADDR_ADDRESS for the same operand. (clear_reload_reg_in_use): Check for other reloads that keep a register in use. (reload_reg_free_for_value_p): handle RELOAD_FOR_OPERAND_ADDRESS / RELOAD_FOR_OPADDR_ADDR. Take into account when an address address reload is only needed for the address reload we are considering. (count_occurrences): Use rtx_equal_p for MEMs. (inc_for_reload): Return instruction that stores into RELOADREG. New argument two, IN, and rtx. Changed all callers. (calculate_needs_all_insns, reload_as_needed): Don't clear after_call for a CLOBBER. Keep track of how many hard registers need to be copied from after_call, and don't clear after_call before we have seen that much copies, or we see a different instruction. From-SVN: r23143

/* Main entry point of this file: search the body of INSN
for values that need reloading and record them with push_reload.
REPLACE nonzero means record also where the values occur
so that subst_reloads can be used.
IND_LEVELS says how many levels of indirection are supported by this
machine; a value of zero means that a memory reference is not a valid
memory address.
LIVE_KNOWN says we have valid information about which hard
regs are live at each point in the program; this is true when
we are called from global_alloc but false when stupid register
allocation has been done.
RELOAD_REG_P if nonzero is a vector indexed by hard reg number
which is nonnegative if the reg has been commandeered for reloading into.
It is copied into STATIC_RELOAD_REG_P and referenced from there
Fix consistency problems with reg_equiv_{mem,address}; Improve reload inheritance; * reload.c (reload_out_reg): New variable. (loc_mentioned_in_p, remove_address_replacements): New functions. (remove_replacements): Deleted. (push_reload): Set reload_out_reg[i]. When merging, also set reload_{in,out}_reg[i], and remove duplicate address reloads. (combine_reloads): Copy reload_out_reg[i]. (find_reloads): Do make_memloc substitution also when reg_equiv_memory_loc[regno] and num_not_at_initial_offset are both nonzero. Include *recog_operand_loc in commutativity operand changes. Generate optional output reloads. Delete reference to n_memlocs. Don't set *recog_operand_loc before processing operands. Call make_memloc in reg_equiv_address code. Set *recog_operand_loc only after processing operands, and only if replace is true. Return a value.

When looking for a store of a value not loaded in order to call delete_output_reload, count_occurences should return 0 for no loads; but discount inherited input reloadill_reg_stored_to. Do checks for extra uses of REG. Changed all callers. Use delete_address_reloads. (reload): Take return value of find_reloads into account. If a no-op set needs more than one reload, delete it. (reload_reg_free_before_p): RELOAD_FOR_INPUT can ignore RELOAD_FOR_INPUT_ADDRESS / RELOAD_FOR_INPADDR_ADDRESS for the same operand. (clear_reload_reg_in_use): Check for other reloads that keep a register in use. (reload_reg_free_for_value_p): handle RELOAD_FOR_OPERAND_ADDRESS / RELOAD_FOR_OPADDR_ADDR. Take into account when an address address reload is only needed for the address reload we are considering. (count_occurrences): Use rtx_equal_p for MEMs. (inc_for_reload): Return instruction that stores into RELOADREG. New argument two, IN, and rtx. Changed all callers. (calculate_needs_all_insns, reload_as_needed): Don't clear after_call for a CLOBBER. Keep track of how many hard registers need to be copied from after_call, and don't clear after_call before we have seen that much copies, or we see a different instruction. From-SVN: r23143

Generate optional output reloads. Delete reference to n_memlocs. Don't set *recog_operand_loc before processing operands. Call make_memloc in reg_equiv_address code. Set *recog_operand_loc only after processing operands, and only if replace is true. Return a value. When changing address reload types for operands that didn't get reloaded, use RELOAD_FOR_OPADDR_ADDRESS for RELOAD_FOR_INPADDR_ADDRESS / RELOAD_FOR_OUTADDR_ADDRESS reloads. Don't emit USEs for pseudo SUBREGs when not replacing. (find_reloads_address): Do make_memloc substitution also when reg_equiv_memory_loc[regno] and num_not_at_initial_offset are both nonzero. (find_reloads_toplev): Likewise. Call make_memloc in reg_equiv_address code. (debug_reload_to_stream): Add code to output reload_out_reg. (make_memloc): Delete local variable i, ifdefed out code, and references to memlocs and n_memlocs. (memlocs, n_memlocs): Delete. (push_secondary_reload): Clear reload_out_reg.

Call forget_old_reloads_1 with contents of reloaded auto_inc expressions if the actual addressing can't be changed to match the auto_inc. (choose_reload_regs): For inheritance, replace reload_reg_free_before_p test with reload_reg_ions. (emit_reload_insns): If reload_in is a MEM, set OLD to reload_in_reg[j]. Don't reload directly from oldequiv; if it's a pseudo with a stack slot, use reload_in[j]. Check that reload_in_reg[j] is a MEM before replacing reload_in from reg_reloaded_contents. Include non-spill registers in reload inheritance processing. Also try to use reload_out_reg to set spill_reg_store / reg_last_reload_reg. In code to set new_spill_reg_store, use single_set to find out if there is a single set. Add code that allows to delete optional output reloads. Add code to allow deletion of output reloads that use no spill reg. At the end, set reload_override_in to oldequiv. Also call delete_output_reload if reload_out_reg is equal to old in oldequiv code. Add code to call delete_output_reload for stores with no matching load. Set / use spill_reg_stored_to. Handle case where secondary output reload uses a temporary, but actual store isn't found. When looking for a store of a value not loaded in order to call delete_output_reload, count_occurences should return 0 for no loads; but discount inherited input reloadill_reg_stored_to. Do checks for extra uses of REG. Changed all callers. Use delete_address_reloads. (reload): Take return value of find_reloads into account. If a no-op set needs more than one reload, delete it. (reload_reg_free_before_p): RELOAD_FOR_INPUT can ignore RELOAD_FOR_INPUT_ADDRESS / RELOAD_FOR_INPADDR_ADDRESS for the same operand. (clear_reload_reg_in_use): Check for other reloads that keep a register in use. (reload_reg_free_for_value_p): handle RELOAD_FOR_OPERAND_ADDRESS / RELOAD_FOR_OPADDR_ADDR. Take into account when an address address reload is only needed for the address reload we are considering.

(calculate_needs_all_insns, reload_as_needed): Don't clear after_call for a CLOBBER. Keep track of how many hard registers need to be copied from after_call, and don't clear after_call before we have seen that much copies, or we see a different instruction. From-SVN: r23143

Fix consistency problems with reg_equiv_{mem,address}; Improve reload inheritance; * reload.c (reload_out_reg): New variable. (loc_mentioned_in_p, remove_address_replacements): New functions. (remove_replacements): Deleted. (push_reload): Set reload_out_reg[i]. When merging, also set reload_{in,out}_reg[i], and remove duplicate address reloads. (combine_reloads): Copy reload_out_reg[i]. (find_reloads): Do make_memloc substitution also when reg_equiv_memory_loc[regno] and num_not_at_initial_offset are both nonzero. Include *recog_operand_loc in commutativity operand changes. Generate optional output reloads. Delete reference to n_memlocs. Don't set *recog_operand_loc before processing operands. Call make_memloc in reg_equiv_address code. Set *recog_operand_loc only after processing operands, and only if replace is true. Return a value. When changing address reload types for operands that didn't get reloaded, use RELOAD_FOR_OPADDR_ADDRESS for RELOAD_FOR_INPADDR_ADDRESS / RELOAD_FOR_OUTADDR_ADDRESS reloads. Don't emit USEs for pseudo SUBREGs when not replacing. (find_reloads_address): Do make_memloc substitution also when reg_equiv_memory_loc[regno] and num_not_at_initial_offset are both nonzero. (find_reloads_toplev): Likewise. Call make_memloc in reg_equiv_address code. (debug_reload_to_stream): Add code to output reload_out_reg. (make_memloc): Delete local variable i, ifdefed out code, and references to memlocs and n_memlocs. (memlocs, n_memlocs): Delete. (push_secondary_reload): Clear reload_out_reg. (find_reloads_address_1): Provide memrefloc argument to all calls to find_reloads_address. In AUTO_INC code, handle non-directly addressable equivalences properly. * reload.h (reload_out_reg, num_not_at_initial_offset): Declare. (find_reloads): Add return type. (remove_address_replacements, deallocate_reload_reg): Declare. * reload1.c (num_not_at_initial_offset): No longer static. (delete_address_reloads, delete_address_reloads_1): Likewise. (deallocate_reload_reg): New function. (spill_reg_stored_to): New array. (eliminate_regs): Don't substitute from reg_equiv_memory_loc. (eliminate_regs_in_insn): Move assignments of previous_offset and max_offset fields, and recalculation of num_not_at_initial_offset into new static function: (update_eliminable_offsets) . (reload_as_needed): Call update_eliminable_offsetss after calling find_reloads. Call forget_old_reloads_1 with contents of reloaded auto_inc expressions if the actual addressing can't be changed to match the auto_inc. (choose_reload_regs): For inheritance, replace reload_reg_free_before_p test with reload_reg_ions. (emit_reload_insns): If reload_in is a MEM, set OLD to reload_in_reg[j]. Don't reload directly from oldequiv; if it's a pseudo with a stack slot, use reload_in[j]. Check that reload_in_reg[j] is a MEM before replacing reload_in from reg_reloaded_contents. Include non-spill registers in reload inheritance processing. Also try to use reload_out_reg to set spill_reg_store / reg_last_reload_reg. In code to set new_spill_reg_store, use single_set to find out if there is a single set. Add code that allows to delete optional output reloads. Add code to allow deletion of output reloads that use no spill reg. At the end, set reload_override_in to oldequiv. Also call delete_output_reload if reload_out_reg is equal to old in oldequiv code. Add code to call delete_output_reload for stores with no matching load. Set / use spill_reg_stored_to. Handle case where secondary output reload uses a temporary, but actual store isn't found. When looking for a store of a value not loaded in order to call delete_output_reload, count_occurences should return 0 for no loads; but discount inherited input reloadill_reg_stored_to. Do checks for extra uses of REG. Changed all callers. Use delete_address_reloads. (reload): Take return value of find_reloads into account. If a no-op set needs more than one reload, delete it. (reload_reg_free_before_p): RELOAD_FOR_INPUT can ignore RELOAD_FOR_INPUT_ADDRESS / RELOAD_FOR_INPADDR_ADDRESS for the same operand. (clear_reload_reg_in_use): Check for other reloads that keep a register in use. (reload_reg_free_for_value_p): handle RELOAD_FOR_OPERAND_ADDRESS / RELOAD_FOR_OPADDR_ADDR. Take into account when an address address reload is only needed for the address reload we are considering. (count_occurrences): Use rtx_equal_p for MEMs. (inc_for_reload): Return instruction that stores into RELOADREG. New argument two, IN, and rtx. Changed all callers. (calculate_needs_all_insns, reload_as_needed): Don't clear after_call for a CLOBBER. Keep track of how many hard registers need to be copied from after_call, and don't clear after_call before we have seen that much copies, or we see a different instruction. From-SVN: r23143

Fix consistency problems with reg_equiv_{mem,address}; Improve reload inheritance; * reload.c (reload_out_reg): New variable. (loc_mentioned_in_p, remove_address_replacements): New functions. (remove_replacements): Deleted. (push_reload): Set reload_out_reg[i]. When merging, also set reload_{in,out}_reg[i], and remove duplicate address reloads. (combine_reloads): Copy reload_out_reg[i]. (find_reloads): Do make_memloc substitution also when reg_equiv_memory_loc[regno] and num_not_at_initial_offset are both nonzero. Include *recog_operand_loc in commutativity operand changes. Generate optional output reloads. Delete reference to n_memlocs. Don't set *recog_operand_loc before processing operands. Call make_memloc in reg_equiv_address code. Set *recog_operand_loc only after processing operands, and only if replace is true. Return a value. When changing address reload types for operands that didn't get reloaded, use RELOAD_FOR_OPADDR_ADDRESS for RELOAD_FOR_INPADDR_ADDRESS / RELOAD_FOR_OUTADDR_ADDRESS reloads. Don't emit USEs for pseudo SUBREGs when not replacing. (find_reloads_address): Do make_memloc substitution also when reg_equiv_memory_loc[regno] and num_not_at_initial_offset are both nonzero. (find_reloads_toplev): Likewise. Call make_memloc in reg_equiv_address code. (debug_reload_to_stream): Add code to output reload_out_reg. (make_memloc): Delete local variable i, ifdefed out code, and references to memlocs and n_memlocs. (memlocs, n_memlocs): Delete. (push_secondary_reload): Clear reload_out_reg. (find_reloads_address_1): Provide memrefloc argument to all calls to find_reloads_address. In AUTO_INC code, handle non-directly addressable equivalences properly. * reload.h (reload_out_reg, num_not_at_initial_offset): Declare. (find_reloads): Add return type. (remove_address_replacements, deallocate_reload_reg): Declare. * reload1.c (num_not_at_initial_offset): No longer static. (delete_address_reloads, delete_address_reloads_1): Likewise. (deallocate_reload_reg): New function. (spill_reg_stored_to): New array. (eliminate_regs): Don't substitute from reg_equiv_memory_loc. (eliminate_regs_in_insn): Move assignments of previous_offset and max_offset fields, and recalculation of num_not_at_initial_offset into new static function: (update_eliminable_offsets) . (reload_as_needed): Call update_eliminable_offsetss after calling find_reloads. Call forget_old_reloads_1 with contents of reloaded auto_inc expressions if the actual addressing can't be changed to match the auto_inc. (choose_reload_regs): For inheritance, replace reload_reg_free_before_p test with reload_reg_ions. (emit_reload_insns): If reload_in is a MEM, set OLD to reload_in_reg[j]. Don't reload directly from oldequiv; if it's a pseudo with a stack slot, use reload_in[j]. Check that reload_in_reg[j] is a MEM before replacing reload_in from reg_reloaded_contents. Include non-spill registers in reload inheritance processing. Also try to use reload_out_reg to set spill_reg_store / reg_last_reload_reg. In code to set new_spill_reg_store, use single_set to find out if there is a single set. Add code that allows to delete optional output reloads. Add code to allow deletion of output reloads that use no spill reg. At the end, set reload_override_in to oldequiv. Also call delete_output_reload if reload_out_reg is equal to old in oldequiv code. Add code to call delete_output_reload for stores with no matching load. Set / use spill_reg_stored_to. Handle case where secondary output reload uses a temporary, but actual store isn't found. When looking for a store of a value not loaded in order to call delete_output_reload, count_occurences should return 0 for no loads; but discount inherited input reloadill_reg_stored_to. Do checks for extra uses of REG. Changed all callers. Use delete_address_reloads. (reload): Take return value of find_reloads into account. If a no-op set needs more than one reload, delete it. (reload_reg_free_before_p): RELOAD_FOR_INPUT can ignore RELOAD_FOR_INPUT_ADDRESS / RELOAD_FOR_INPADDR_ADDRESS for the same operand. (clear_reload_reg_in_use): Check for other reloads that keep a register in use. (reload_reg_free_for_value_p): handle RELOAD_FOR_OPERAND_ADDRESS / RELOAD_FOR_OPADDR_ADDR. Take into account when an address address reload is only needed for the address reload we are considering. (count_occurrences): Use rtx_equal_p for MEMs. (inc_for_reload): Return instruction that stores into RELOADREG. New argument two, IN, and rtx. Changed all callers. (calculate_needs_all_insns, reload_as_needed): Don't clear after_call for a CLOBBER. Keep track of how many hard registers need to be copied from after_call, and don't clear after_call before we have seen that much copies, or we see a different instruction. From-SVN: r23143

Fix consistency problems with reg_equiv_{mem,address}; Improve reload inheritance; * reload.c (reload_out_reg): New variable. (loc_mentioned_in_p, remove_address_replacements): New functions. (remove_replacements): Deleted. (push_reload): Set reload_out_reg[i]. When merging, also set reload_{in,out}_reg[i], and remove duplicate address reloads. (combine_reloads): Copy reload_out_reg[i]. (find_reloads): Do make_memloc substitution also when reg_equiv_memory_loc[regno] and num_not_at_initial_offset are both nonzero. Include *recog_operand_loc in commutativity operand changes. Generate optional output reloads. Delete reference to n_memlocs. Don't set *recog_operand_loc before processing operands. Call make_memloc in reg_equiv_address code. Set *recog_operand_loc only after processing operands, and only if replace is true. Return a value. When changing address reload types for operands that didn't get reloaded, use RELOAD_FOR_OPADDR_ADDRESS for RELOAD_FOR_INPADDR_ADDRESS / RELOAD_FOR_OUTADDR_ADDRESS reloads. Don't emit USEs for pseudo SUBREGs when not replacing. (find_reloads_address): Do make_memloc substitution also when reg_equiv_memory_loc[regno] and num_not_at_initial_offset are both nonzero. (find_reloads_toplev): Likewise. Call make_memloc in reg_equiv_address code. (debug_reload_to_stream): Add code to output reload_out_reg. (make_memloc): Delete local variable i, ifdefed out code, and references to memlocs and n_memlocs. (memlocs, n_memlocs): Delete. (push_secondary_reload): Clear reload_out_reg. (find_reloads_address_1): Provide memrefloc argument to all calls to find_reloads_address. In AUTO_INC code, handle non-directly addressable equivalences properly. * reload.h (reload_out_reg, num_not_at_initial_offset): Declare. (find_reloads): Add return type. (remove_address_replacements, deallocate_reload_reg): Declare. * reload1.c (num_not_at_initial_offset): No longer static. (delete_address_reloads, delete_address_reloads_1): Likewise. (deallocate_reload_reg): New function. (spill_reg_stored_to): New array. (eliminate_regs): Don't substitute from reg_equiv_memory_loc. (eliminate_regs_in_insn): Move assignments of previous_offset and max_offset fields, and recalculation of num_not_at_initial_offset into new static function: (update_eliminable_offsets) . (reload_as_needed): Call update_eliminable_offsetss after calling find_reloads. Call forget_old_reloads_1 with contents of reloaded auto_inc expressions if the actual addressing can't be changed to match the auto_inc. (choose_reload_regs): For inheritance, replace reload_reg_free_before_p test with reload_reg_ions. (emit_reload_insns): If reload_in is a MEM, set OLD to reload_in_reg[j]. Don't reload directly from oldequiv; if it's a pseudo with a stack slot, use reload_in[j]. Check that reload_in_reg[j] is a MEM before replacing reload_in from reg_reloaded_contents. Include non-spill registers in reload inheritance processing. Also try to use reload_out_reg to set spill_reg_store / reg_last_reload_reg. In code to set new_spill_reg_store, use single_set to find out if there is a single set. Add code that allows to delete optional output reloads. Add code to allow deletion of output reloads that use no spill reg. At the end, set reload_override_in to oldequiv. Also call delete_output_reload if reload_out_reg is equal to old in oldequiv code. Add code to call delete_output_reload for stores with no matching load. Set / use spill_reg_stored_to. Handle case where secondary output reload uses a temporary, but actual store isn't found. When looking for a store of a value not loaded in order to call delete_output_reload, count_occurences should return 0 for no loads; but discount inherited input reloadill_reg_stored_to. Do checks for extra uses of REG. Changed all callers. Use delete_address_reloads. (reload): Take return value of find_reloads into account. If a no-op set needs more than one reload, delete it. (reload_reg_free_before_p): RELOAD_FOR_INPUT can ignore RELOAD_FOR_INPUT_ADDRESS / RELOAD_FOR_INPADDR_ADDRESS for the same operand. (clear_reload_reg_in_use): Check for other reloads that keep a register in use. (reload_reg_free_for_value_p): handle RELOAD_FOR_OPERAND_ADDRESS / RELOAD_FOR_OPADDR_ADDR. Take into account when an address address reload is only needed for the address reload we are considering. (count_occurrences): Use rtx_equal_p for MEMs. (inc_for_reload): Return instruction that stores into RELOADREG. New argument two, IN, and rtx. Changed all callers. (calculate_needs_all_insns, reload_as_needed): Don't clear after_call for a CLOBBER. Keep track of how many hard registers need to be copied from after_call, and don't clear after_call before we have seen that much copies, or we see a different instruction. From-SVN: r23143

(reload_reg_free_before_p): RELOAD_FOR_INPUT can ignore RELOAD_FOR_INPUT_ADDRESS / RELOAD_FOR_INPADDR_ADDRESS for the same operand. (clear_reload_reg_in_use): Check for other reloads that keep a register in use. (reload_reg_free_for_value_p): handle RELOAD_FOR_OPERAND_ADDRESS / RELOAD_FOR_OPADDR_ADDR. Take into account when an address address reload is only needed for the address reload we are considering. (count_occurrences): Use rtx_equal_p for MEMs. (inc_for_reload): Return instruction that stores into RELOADREG. New argument two, IN, and rtx. Changed all callers. (calculate_needs_all_insns, reload_as_needed): Don't clear after_call for a CLOBBER. Keep track of how many hard registers need to be copied from after_call, and don't clear after_call before we have seen that much copies, or we see a different instruction. From-SVN: r23143

(find_reloads): Do make_memloc substitution also when reg_equiv_memory_loc[regno] and num_not_at_initial_offset are both nonzero. Include *recog_operand_loc in commutativity operand changes. Generate optional output reloads. Delete reference to n_memlocs. Don't set *recog_operand_loc before processing operands. Call make_memloc in reg_equiv_address code. Set *recog_operand_loc only after processing operands, and only if replace is true. Return a value. When changing address reload types for operands that didn't get reloaded, use RELOAD_FOR_OPADDR_ADDRESS for RELOAD_FOR_INPADDR_ADDRESS / RELOAD_FOR_OUTADDR_ADDRESS reloads. Don't emit USEs for pseudo SUBREGs when not replacing. (find_reloads_address): Do make_memloc substitution also when reg_equiv_memory_loc[regno] and num_not_at_initial_offset are both nonzero.

(remove_address_replacements, deallocate_reload_reg): Declare. * reload1.c (num_not_at_initial_offset): No longer static. (delete_address_reloads, delete_address_reloads_1): Likewise. (deallocate_reload_reg): New function. (spill_reg_stored_to): New array. (eliminate_regs): Don't substitute from reg_equiv_memory_loc. (eliminate_regs_in_insn): Move assignments of previous_offset and max_offset fields, and recalculation of num_not_at_initial_offset into new static function: (update_eliminable_offsets) . (reload_as_needed): Call update_eliminable_offsetss after calling find_reloads. Call forget_old_reloads_1 with contents of reloaded auto_inc expressions if the actual addressing can't be changed to match the auto_inc. (choose_reload_regs): For inheritance, replace reload_reg_free_before_p test with reload_reg_ions. (emit_reload_insns): If reload_in is a MEM, set OLD to reload_in_reg[j]. Don't reload directly from oldequiv; if it's a pseudo with a stack slot, use reload_in[j]. Check that reload_in_reg[j] is a MEM before replacing reload_in from reg_reloaded_contents. Include non-spill registers in reload inheritance processing. Also try to use reload_out_reg to set spill_reg_store / reg_last_reload_reg. In code to set new_spill_reg_store, use single_set to find out if there is a single set. Add code that allows to delete optional output reloads. Add code to allow deletion of output reloads that use no spill reg. At the end, set reload_override_in to oldequiv. Also call delete_output_reload if reload_out_reg is equal to old in oldequiv code. Add code to call delete_output_reload for stores with no matching load. Set / use spill_reg_stored_to. Handle case where secondary output reload uses a temporary, but actual store isn't found. When looking for a store of a value not loaded in order to call delete_output_reload, count_occurences should return 0 for no loads; but discount inherited input reloadill_reg_stored_to. Do checks for extra uses of REG. Changed all callers. Use delete_address_reloads. (reload): Take return value of find_reloads into account. If a no-op set needs more than one reload, delete it. (reload_reg_free_before_p): RELOAD_FOR_INPUT can ignore RELOAD_FOR_INPUT_ADDRESS / RELOAD_FOR_INPADDR_ADDRESS for the same operand. (clear_reload_reg_in_use): Check for other reloads that keep a register in use. (reload_reg_free_for_value_p): handle RELOAD_FOR_OPERAND_ADDRESS / RELOAD_FOR_OPADDR_ADDR. Take into account when an address address reload is only needed for the address reload we are considering. (count_occurrences): Use rtx_equal_p for MEMs. (inc_for_reload): Return instruction that stores into RELOADREG. New argument two, IN, and rtx. Changed all callers. (calculate_needs_all_insns, reload_as_needed): Don't clear after_call for a CLOBBER. Keep track of how many hard registers need to be copied from after_call, and don't clear after_call before we have seen that much copies, or we see a different instruction. From-SVN: r23143

If a reload is for the address of an operand and we didn't reload
that operand, change the type. Similarly, change the operand number
of a reload when two operands match. If a reload is optional, treat it
as though the operand isn't reloaded.
??? This latter case is somewhat odd because if we do the optional
reload, it means the object is hanging around. Thus we need only
do the address reload if the optional reload was NOT done.
Change secondary reloads to be the address type of their operand, not
the normal type.
If an operand's reload is now RELOAD_OTHER, change any
RELOAD_FOR_INPUT_ADDRESS reloads of that operand to
RELOAD_FOR_OTHER_ADDRESS. */

Fix consistency problems with reg_equiv_{mem,address}; Improve reload inheritance; * reload.c (reload_out_reg): New variable. (loc_mentioned_in_p, remove_address_replacements): New functions. (remove_replacements): Deleted. (push_reload): Set reload_out_reg[i]. When merging, also set reload_{in,out}_reg[i], and remove duplicate address reloads. (combine_reloads): Copy reload_out_reg[i]. (find_reloads): Do make_memloc substitution also when reg_equiv_memory_loc[regno] and num_not_at_initial_offset are both nonzero. Include *recog_operand_loc in commutativity operand changes.

Set *recog_operand_loc only after processing operands, and only if replace is true. Return a value. When changing address reload types for operands that didn't get reloaded, use RELOAD_FOR_OPADDR_ADDRESS for RELOAD_FOR_INPADDR_ADDRESS / RELOAD_FOR_OUTADDR_ADDRESS reloads. Don't emit USEs for pseudo SUBREGs when not replacing. (find_reloads_address): Do make_memloc substitution also when reg_equiv_memory_loc[regno] and num_not_at_initial_offset are both nonzero. (find_reloads_toplev): Likewise. Call make_memloc in reg_equiv_address code. (debug_reload_to_stream): Add code to output reload_out_reg. (make_memloc): Delete local variable i, ifdefed out code, and references to memlocs and n_memlocs. (memlocs, n_memlocs): Delete. (push_secondary_reload): Clear reload_out_reg.

(eliminate_regs_in_insn): Move assignments of previous_offset and max_offset fields, and recalculation of num_not_at_initial_offset into new static function: (update_eliminable_offsets) . (reload_as_needed): Call update_eliminable_offsetss after calling find_reloads. Call forget_old_reloads_1 with contents of reloaded auto_inc expressions if the actual addressing can't be changed to match the auto_inc. (choose_reload_regs): For inheritance, replace reload_reg_free_before_p test with reload_reg_ions. (emit_reload_insns): If reload_in is a MEM, set OLD to reload_in_reg[j]. Don't reload directly from oldequiv; if it's a pseudo with a stack slot, use reload_in[j]. Check that reload_in_reg[j] is a MEM before replacing reload_in from reg_reloaded_contents. Include non-spill registers in reload inheritance processing. Also try to use reload_out_reg to set spill_reg_store / reg_last_reload_reg. In code to set new_spill_reg_store, use single_set to find out if there is a single set. Add code that allows to delete optional output reloads. Add code to allow deletion of output reloads that use no spill reg. At the end, set reload_override_in to oldequiv. Also call delete_output_reload if reload_out_reg is equal to old in oldequiv code. Add code to call delete_output_reload for stores with no matching load. Set / use spill_reg_stored_to. Handle case where secondary output reload uses a temporary, but actual store isn't found. When looking for a store of a value not loaded in order to call delete_output_reload, count_occurences should return 0 for no loads; but discount inherited input reloadill_reg_stored_to. Do checks for extra uses of REG. Changed all callers. Use delete_address_reloads. (reload): Take return value of find_reloads into account. If a no-op set needs more than one reload, delete it. (reload_reg_free_before_p): RELOAD_FOR_INPUT can ignore RELOAD_FOR_INPUT_ADDRESS / RELOAD_FOR_INPADDR_ADDRESS for the same operand. (clear_reload_reg_in_use): Check for other reloads that keep a register in use. (reload_reg_free_for_value_p): handle RELOAD_FOR_OPERAND_ADDRESS / RELOAD_FOR_OPADDR_ADDR. Take into account when an address address reload is only needed for the address reload we are considering. (count_occurrences): Use rtx_equal_p for MEMs. (inc_for_reload): Return instruction that stores into RELOADREG. New argument two, IN, and rtx. Changed all callers. (calculate_needs_all_insns, reload_as_needed): Don't clear after_call for a CLOBBER. Keep track of how many hard registers need to be copied from after_call, and don't clear after_call before we have seen that much copies, or we see a different instruction. From-SVN: r23143

/* Scan all the reloads, and check for RELOAD_FOR_OPERAND_ADDRESS reloads.
If we have more than one, then convert all RELOAD_FOR_OPADDR_ADDR
reloads to RELOAD_FOR_OPERAND_ADDRESS reloads.
choose_reload_regs assumes that RELOAD_FOR_OPADDR_ADDR reloads never
conflict with RELOAD_FOR_OPERAND_ADDRESS reloads. This is true for a
single pair of RELOAD_FOR_OPADDR_ADDR/RELOAD_FOR_OPERAND_ADDRESS reloads.
However, if there is more than one RELOAD_FOR_OPERAND_ADDRESS reload,
then a RELOAD_FOR_OPADDR_ADDR reload conflicts with all
RELOAD_FOR_OPERAND_ADDRESS reloads other than the one that uses it.
This is complicated by the fact that a single operand can have more
than one RELOAD_FOR_OPERAND_ADDRESS reload. It is very difficult to fix
choose_reload_regs without affecting code quality, and cases that
actually fail are extremely rare, so it turns out to be better to fix
the problem here by not generating cases that choose_reload_regs will
fail for. */

Include non-spill registers in reload inheritance processing. Also try to use reload_out_reg to set spill_reg_store / reg_last_reload_reg.

(remove_replacements): Deleted. (push_reload): Set reload_out_reg[i]. When merging, also set reload_{in,out}_reg[i], and remove duplicate address reloads. (combine_reloads): Copy reload_out_reg[i]. (find_reloads): Do make_memloc substitution also when reg_equiv_memory_loc[regno] and num_not_at_initial_offset are both nonzero. Include *recog_operand_loc in commutativity operand changes. Generate optional output reloads. Delete reference to n_memlocs. Don't set *recog_operand_loc before processing operands. Call make_memloc in reg_equiv_address code. Set *recog_operand_loc only after processing operands, and only if replace is true. Return a value. When changing address reload types for operands that didn't get reloaded, use RELOAD_FOR_OPADDR_ADDRESS for RELOAD_FOR_INPADDR_ADDRESS / RELOAD_FOR_OUTADDR_ADDRESS reloads. Don't emit USEs for pseudo SUBREGs when not replacing. (find_reloads_address): Do make_memloc substitution also when reg_equiv_memory_loc[regno] and num_not_at_initial_offset are both nonzero. (find_reloads_toplev): Likewise. Call make_memloc in reg_equiv_address code. (debug_reload_to_stream): Add code to output reload_out_reg. (make_memloc): Delete local variable i, ifdefed out code, and references to memlocs and n_memlocs. (memlocs, n_memlocs): Delete. (push_secondary_reload): Clear reload_out_reg. (find_reloads_address_1): Provide memrefloc argument to all calls to find_reloads_address. In AUTO_INC code, handle non-directly addressable equivalences properly. * reload.h (reload_out_reg, num_not_at_initial_offset): Declare. (find_reloads): Add return type. (remove_address_replacements, deallocate_reload_reg): Declare. * reload1.c (num_not_at_initial_offset): No longer static. (delete_address_reloads, delete_address_reloads_1): Likewise. (deallocate_reload_reg): New function. (spill_reg_stored_to): New array. (eliminate_regs): Don't substitute from reg_equiv_memory_loc. (eliminate_regs_in_insn): Move assignments of previous_offset and max_offset fields, and recalculation of num_not_at_initial_offset into new static function: (update_eliminable_offsets) . (reload_as_needed): Call update_eliminable_offsetss after calling find_reloads. Call forget_old_reloads_1 with contents of reloaded auto_inc expressions if the actual addressing can't be changed to match the auto_inc. (choose_reload_regs): For inheritance, replace reload_reg_free_before_p test with reload_reg_ions. (emit_reload_insns): If reload_in is a MEM, set OLD to reload_in_reg[j]. Don't reload directly from oldequiv; if it's a pseudo with a stack slot, use reload_in[j]. Check that reload_in_reg[j] is a MEM before replacing reload_in from reg_reloaded_contents. Include non-spill registers in reload inheritance processing. Also try to use reload_out_reg to set spill_reg_store / reg_last_reload_reg. In code to set new_spill_reg_store, use single_set to find out if there is a single set. Add code that allows to delete optional output reloads. Add code to allow deletion of output reloads that use no spill reg. At the end, set reload_override_in to oldequiv. Also call delete_output_reload if reload_out_reg is equal to old in oldequiv code. Add code to call delete_output_reload for stores with no matching load. Set / use spill_reg_stored_to. Handle case where secondary output reload uses a temporary, but actual store isn't found. When looking for a store of a value not loaded in order to call delete_output_reload, count_occurences should return 0 for no loads; but discount inherited input reloadill_reg_stored_to. Do checks for extra uses of REG. Changed all callers. Use delete_address_reloads. (reload): Take return value of find_reloads into account. If a no-op set needs more than one reload, delete it. (reload_reg_free_before_p): RELOAD_FOR_INPUT can ignore RELOAD_FOR_INPUT_ADDRESS / RELOAD_FOR_INPADDR_ADDRESS for the same operand. (clear_reload_reg_in_use): Check for other reloads that keep a register in use. (reload_reg_free_for_value_p): handle RELOAD_FOR_OPERAND_ADDRESS / RELOAD_FOR_OPADDR_ADDR. Take into account when an address address reload is only needed for the address reload we are considering. (count_occurrences): Use rtx_equal_p for MEMs. (inc_for_reload): Return instruction that stores into RELOADREG. New argument two, IN, and rtx. Changed all callers. (calculate_needs_all_insns, reload_as_needed): Don't clear after_call for a CLOBBER. Keep track of how many hard registers need to be copied from after_call, and don't clear after_call before we have seen that much copies, or we see a different instruction. From-SVN: r23143

/* Check for SUBREG containing a REG that's equivalent to a
constant. If the constant has a known value, truncate it
right now. Similarly if we are extracting a single-word of a
multi-word constant. If the constant is symbolic, allow it
to be substituted normally. push_reload will strip the
subreg later. The constant must not be VOIDmode, because we
will lose the mode of the register (this should never happen
because one of the cases above should handle it). */

Generate optional output reloads. Delete reference to n_memlocs. Don't set *recog_operand_loc before processing operands. Call make_memloc in reg_equiv_address code. Set *recog_operand_loc only after processing operands, and only if replace is true. Return a value. When changing address reload types for operands that didn't get reloaded, use RELOAD_FOR_OPADDR_ADDRESS for RELOAD_FOR_INPADDR_ADDRESS / RELOAD_FOR_OUTADDR_ADDRESS reloads. Don't emit USEs for pseudo SUBREGs when not replacing. (find_reloads_address): Do make_memloc substitution also when reg_equiv_memory_loc[regno] and num_not_at_initial_offset are both nonzero. (find_reloads_toplev): Likewise. Call make_memloc in reg_equiv_address code. (debug_reload_to_stream): Add code to output reload_out_reg. (make_memloc): Delete local variable i, ifdefed out code, and references to memlocs and n_memlocs. (memlocs, n_memlocs): Delete. (push_secondary_reload): Clear reload_out_reg. (find_reloads_address_1): Provide memrefloc argument to all calls to find_reloads_address. In AUTO_INC code, handle non-directly addressable equivalences properly. * reload.h (reload_out_reg, num_not_at_initial_offset): Declare. (find_reloads): Add return type. (remove_address_replacements, deallocate_reload_reg): Declare. * reload1.c (num_not_at_initial_offset): No longer static. (delete_address_reloads, delete_address_reloads_1): Likewise. (deallocate_reload_reg): New function. (spill_reg_stored_to): New array. (eliminate_regs): Don't substitute from reg_equiv_memory_loc. (eliminate_regs_in_insn): Move assignments of previous_offset and max_offset fields, and recalculation of num_not_at_initial_offset into new static function: (update_eliminable_offsets) . (reload_as_needed): Call update_eliminable_offsetss after calling find_reloads. Call forget_old_reloads_1 with contents of reloaded auto_inc expressions if the actual addressing can't be changed to match the auto_inc. (choose_reload_regs): For inheritance, replace reload_reg_free_before_p test with reload_reg_ions. (emit_reload_insns): If reload_in is a MEM, set OLD to reload_in_reg[j]. Don't reload directly from oldequiv; if it's a pseudo with a stack slot, use reload_in[j]. Check that reload_in_reg[j] is a MEM before replacing reload_in from reg_reloaded_contents. Include non-spill registers in reload inheritance processing. Also try to use reload_out_reg to set spill_reg_store / reg_last_reload_reg. In code to set new_spill_reg_store, use single_set to find out if there is a single set. Add code that allows to delete optional output reloads. Add code to allow deletion of output reloads that use no spill reg. At the end, set reload_override_in to oldequiv. Also call delete_output_reload if reload_out_reg is equal to old in oldequiv code. Add code to call delete_output_reload for stores with no matching load. Set / use spill_reg_stored_to. Handle case where secondary output reload uses a temporary, but actual store isn't found. When looking for a store of a value not loaded in order to call delete_output_reload, count_occurences should return 0 for no loads; but discount inherited input reloadill_reg_stored_to. Do checks for extra uses of REG. Changed all callers. Use delete_address_reloads. (reload): Take return value of find_reloads into account. If a no-op set needs more than one reload, delete it. (reload_reg_free_before_p): RELOAD_FOR_INPUT can ignore RELOAD_FOR_INPUT_ADDRESS / RELOAD_FOR_INPADDR_ADDRESS for the same operand. (clear_reload_reg_in_use): Check for other reloads that keep a register in use. (reload_reg_free_for_value_p): handle RELOAD_FOR_OPERAND_ADDRESS / RELOAD_FOR_OPADDR_ADDR. Take into account when an address address reload is only needed for the address reload we are considering. (count_occurrences): Use rtx_equal_p for MEMs. (inc_for_reload): Return instruction that stores into RELOADREG. New argument two, IN, and rtx. Changed all callers. (calculate_needs_all_insns, reload_as_needed): Don't clear after_call for a CLOBBER. Keep track of how many hard registers need to be copied from after_call, and don't clear after_call before we have seen that much copies, or we see a different instruction. From-SVN: r23143

/* Record all reloads needed for handling memory address AD
which appears in *LOC in a memory reference to mode MODE
which itself is found in location *MEMREFLOC.
Note that we take shortcuts assuming that no multi-reg machine mode
occurs as part of an address.
Add prototypes for all static functions and clean up some definitions. (struct decompose): Move to before function declarations. (secondary_memlocs_elim): One per operand, not per mode. (get_secondary_mem): Accept and use reload description (opnum and type). (push_reload): Accept and use new reload description instead of old NEEDED_FOR. Define two new macros: MERGEABLE_RELOADS and MERGE_TO_OTHER. Use these macros to see if reloads can be merged and how to do it. (transfer_replacements): New function. (combine_reloads): Refine when we can combine reloads. (find_reloads): Use new method of tracking what a reload is for. When we make a CLOBBER insn, do so with DImode. Merge cases of making optional reloads, avoid making output-only optional reloads, refine when we may not make in-out optional reloads, and make an optional reload for a pair of matching operands. (find_reloads_toplev, find_reloads_address{,_1, part}): Accept and use reload description. (forget_volatility): Delete long-obsolete function. From-SVN: r3911

OPNUM and TYPE specify the purpose of this reload.

IND_LEVELS says how many levels of indirect addressing this machine
supports.
Include expr.h. (find_reloads_address, find_reloads_address_1): New argument INSN. (find_reloads_address_1): Reload inside of p{re,ost}_{in,de}c instead of entire p{re,ost}_{in,de}c where appropriate. From-SVN: r13706

INSN, if nonzero, is the insn in which we do the reload. It is used
Fix consistency problems with reg_equiv_{mem,address}; Improve reload inheritance; * reload.c (reload_out_reg): New variable. (loc_mentioned_in_p, remove_address_replacements): New functions. (remove_replacements): Deleted. (push_reload): Set reload_out_reg[i]. When merging, also set reload_{in,out}_reg[i], and remove duplicate address reloads. (combine_reloads): Copy reload_out_reg[i]. (find_reloads): Do make_memloc substitution also when reg_equiv_memory_loc[regno] and num_not_at_initial_offset are both nonzero. Include *recog_operand_loc in commutativity operand changes. Generate optional output reloads. Delete reference to n_memlocs. Don't set *recog_operand_loc before processing operands. Call make_memloc in reg_equiv_address code. Set *recog_operand_loc only after processing operands, and only if replace is true. Return a value. When changing address reload types for operands that didn't get reloaded, use RELOAD_FOR_OPADDR_ADDRESS for RELOAD_FOR_INPADDR_ADDRESS / RELOAD_FOR_OUTADDR_ADDRESS reloads. Don't emit USEs for pseudo SUBREGs when not replacing. (find_reloads_address): Do make_memloc substitution also when reg_equiv_memory_loc[regno] and num_not_at_initial_offset are both nonzero. (find_reloads_toplev): Likewise. Call make_memloc in reg_equiv_address code. (debug_reload_to_stream): Add code to output reload_out_reg. (make_memloc): Delete local variable i, ifdefed out code, and references to memlocs and n_memlocs. (memlocs, n_memlocs): Delete. (push_secondary_reload): Clear reload_out_reg. (find_reloads_address_1): Provide memrefloc argument to all calls to find_reloads_address. In AUTO_INC code, handle non-directly addressable equivalences properly. * reload.h (reload_out_reg, num_not_at_initial_offset): Declare. (find_reloads): Add return type. (remove_address_replacements, deallocate_reload_reg): Declare. * reload1.c (num_not_at_initial_offset): No longer static. (delete_address_reloads, delete_address_reloads_1): Likewise. (deallocate_reload_reg): New function. (spill_reg_stored_to): New array. (eliminate_regs): Don't substitute from reg_equiv_memory_loc. (eliminate_regs_in_insn): Move assignments of previous_offset and max_offset fields, and recalculation of num_not_at_initial_offset into new static function: (update_eliminable_offsets) . (reload_as_needed): Call update_eliminable_offsetss after calling find_reloads. Call forget_old_reloads_1 with contents of reloaded auto_inc expressions if the actual addressing can't be changed to match the auto_inc. (choose_reload_regs): For inheritance, replace reload_reg_free_before_p test with reload_reg_ions. (emit_reload_insns): If reload_in is a MEM, set OLD to reload_in_reg[j]. Don't reload directly from oldequiv; if it's a pseudo with a stack slot, use reload_in[j]. Check that reload_in_reg[j] is a MEM before replacing reload_in from reg_reloaded_contents. Include non-spill registers in reload inheritance processing. Also try to use reload_out_reg to set spill_reg_store / reg_last_reload_reg. In code to set new_spill_reg_store, use single_set to find out if there is a single set. Add code that allows to delete optional output reloads. Add code to allow deletion of output reloads that use no spill reg. At the end, set reload_override_in to oldequiv. Also call delete_output_reload if reload_out_reg is equal to old in oldequiv code. Add code to call delete_output_reload for stores with no matching load. Set / use spill_reg_stored_to. Handle case where secondary output reload uses a temporary, but actual store isn't found. When looking for a store of a value not loaded in order to call delete_output_reload, count_occurences should return 0 for no loads; but discount inherited input reloadill_reg_stored_to. Do checks for extra uses of REG. Changed all callers. Use delete_address_reloads. (reload): Take return value of find_reloads into account. If a no-op set needs more than one reload, delete it. (reload_reg_free_before_p): RELOAD_FOR_INPUT can ignore RELOAD_FOR_INPUT_ADDRESS / RELOAD_FOR_INPADDR_ADDRESS for the same operand. (clear_reload_reg_in_use): Check for other reloads that keep a register in use. (reload_reg_free_for_value_p): handle RELOAD_FOR_OPERAND_ADDRESS / RELOAD_FOR_OPADDR_ADDR. Take into account when an address address reload is only needed for the address reload we are considering. (count_occurrences): Use rtx_equal_p for MEMs. (inc_for_reload): Return instruction that stores into RELOADREG. New argument two, IN, and rtx. Changed all callers. (calculate_needs_all_insns, reload_as_needed): Don't clear after_call for a CLOBBER. Keep track of how many hard registers need to be copied from after_call, and don't clear after_call before we have seen that much copies, or we see a different instruction. From-SVN: r23143

to determine if we may generate output reloads, and where to put USEs
for pseudos that we have to replace with stack slots.
Include expr.h. (find_reloads_address, find_reloads_address_1): New argument INSN. (find_reloads_address_1): Reload inside of p{re,ost}_{in,de}c instead of entire p{re,ost}_{in,de}c where appropriate. From-SVN: r13706

reload.c (find_reloads_address): Make return value tri-state. * reload.c (find_reloads_address): Make return value tri-state. Return -1 if LEGITIMIZE_RELOAD_ADDRESS succeeded. (find_reloads): Assume that reloaded addresses match 'o' or EXTRA_MEMORY_CONSTRAINT constraints only if find_reloads_address returned 1 (not -1). Omit optional reloads for address operands only if find_reloads_address returned 1 (not -1). * config/s390/s390.c (legitimize_reload_address): New function. * config/s390/s390-protos.h (legitimize_reload_address): Declare. * config/s390/s390.h (LEGITIMIZE_RELOAD_ADDRESS): Define. Call legitimize_reload_address. From-SVN: r86388
2004-08-23 00:09:12 +02:00
Value is one if this address is reloaded or replaced as a whole; it is
zero if the top level of this address was not reloaded or replaced, and
it is -1 if it may or may not have been reloaded or replaced.

1992-02-28 11:23:25 +01:00
Note that there is no verification that the address will be valid after
this routine does its work. Instead, we rely on the fact that the address
was valid when reload started. So we need only undo things that reload
could have broken. These are wrong register types, pseudos not allocated
to a hard register, and frame pointer elimination. */

Fix consistency problems with reg_equiv_{mem,address}; Improve reload inheritance; * reload.c (reload_out_reg): New variable. (loc_mentioned_in_p, remove_address_replacements): New functions. (remove_replacements): Deleted. (push_reload): Set reload_out_reg[i]. When merging, also set reload_{in,out}_reg[i], and remove duplicate address reloads. (combine_reloads): Copy reload_out_reg[i]. (find_reloads): Do make_memloc substitution also when reg_equiv_memory_loc[regno] and num_not_at_initial_offset are both nonzero. Include *recog_operand_loc in commutativity operand changes. Generate optional output reloads. Delete reference to n_memlocs. Don't set *recog_operand_loc before processing operands. Call make_memloc in reg_equiv_address code. Set *recog_operand_loc only after processing operands, and only if replace is true. Return a value. When changing address reload types for operands that didn't get reloaded, use RELOAD_FOR_OPADDR_ADDRESS for RELOAD_FOR_INPADDR_ADDRESS / RELOAD_FOR_OUTADDR_ADDRESS reloads. Don't emit USEs for pseudo SUBREGs when not replacing. (find_reloads_address): Do make_memloc substitution also when reg_equiv_memory_loc[regno] and num_not_at_initial_offset are both nonzero.

(reload_as_needed): Call update_eliminable_offsetss after calling find_reloads. Call forget_old_reloads_1 with contents of reloaded auto_inc expressions if the actual addressing can't be changed to match the auto_inc. (choose_reload_regs): For inheritance, replace reload_reg_free_before_p test with reload_reg_ions. (emit_reload_insns): If reload_in is a MEM, set OLD to reload_in_reg[j]. Don't reload directly from oldequiv; if it's a pseudo with a stack slot, use reload_in[j]. Check that reload_in_reg[j] is a MEM before replacing reload_in from reg_reloaded_contents. Include non-spill registers in reload inheritance processing. Also try to use reload_out_reg to set spill_reg_store / reg_last_reload_reg. In code to set new_spill_reg_store, use single_set to find out if there is a single set. Add code that allows to delete optional output reloads. Add code to allow deletion of output reloads that use no spill reg. At the end, set reload_override_in to oldequiv. Also call delete_output_reload if reload_out_reg is equal to old in oldequiv code. Add code to call delete_output_reload for stores with no matching load. Set / use spill_reg_stored_to. Handle case where secondary output reload uses a temporary, but actual store isn't found. When looking for a store of a value not loaded in order to call delete_output_reload, count_occurences should return 0 for no loads; but discount inherited input reloadill_reg_stored_to. Do checks for extra uses of REG. Changed all callers. Use delete_address_reloads. (reload): Take return value of find_reloads into account. If a no-op set needs more than one reload, delete it. (reload_reg_free_before_p): RELOAD_FOR_INPUT can ignore RELOAD_FOR_INPUT_ADDRESS / RELOAD_FOR_INPADDR_ADDRESS for the same operand. (clear_reload_reg_in_use): Check for other reloads that keep a register in use. (reload_reg_free_for_value_p): handle RELOAD_FOR_OPERAND_ADDRESS / RELOAD_FOR_OPADDR_ADDR.

Fix consistency problems with reg_equiv_{mem,address}; Improve reload inheritance; * reload.c (reload_out_reg): New variable. (loc_mentioned_in_p, remove_address_replacements): New functions. (remove_replacements): Deleted. (push_reload): Set reload_out_reg[i]. When merging, also set reload_{in,out}_reg[i], and remove duplicate address reloads. (combine_reloads): Copy reload_out_reg[i]. (find_reloads): Do make_memloc substitution also when reg_equiv_memory_loc[regno] and num_not_at_initial_offset are both nonzero. Include *recog_operand_loc in commutativity operand changes. Generate optional output reloads. Delete reference to n_memlocs. Don't set *recog_operand_loc before processing operands. Call make_memloc in reg_equiv_address code. Set *recog_operand_loc only after processing operands, and only if replace is true. Return a value. When changing address reload types for operands that didn't get reloaded, use RELOAD_FOR_OPADDR_ADDRESS for RELOAD_FOR_INPADDR_ADDRESS / RELOAD_FOR_OUTADDR_ADDRESS reloads. Don't emit USEs for pseudo SUBREGs when not replacing. (find_reloads_address): Do make_memloc substitution also when reg_equiv_memory_loc[regno] and num_not_at_initial_offset are both nonzero. (find_reloads_toplev): Likewise. Call make_memloc in reg_equiv_address code. (debug_reload_to_stream): Add code to output reload_out_reg.

(find_reloads_address_1): Provide memrefloc argument to all calls to find_reloads_address. In AUTO_INC code, handle non-directly addressable equivalences properly. * reload.h (reload_out_reg, num_not_at_initial_offset): Declare. (find_reloads): Add return type.

(reload_as_needed): Call update_eliminable_offsetss after calling find_reloads. Call forget_old_reloads_1 with contents of reloaded auto_inc expressions if the actual addressing can't be changed to match the auto_inc. (choose_reload_regs): For inheritance, replace reload_reg_free_before_p test with reload_reg_ions. (emit_reload_insns): If reload_in is a MEM, set OLD to reload_in_reg[j]. Don't reload directly from oldequiv; if it's a pseudo with a stack slot, use reload_in[j]. Check that reload_in_reg[j] is a MEM before replacing reload_in from reg_reloaded_contents. Include non-spill registers in reload inheritance processing. Also try to use reload_out_reg to set spill_reg_store / reg_last_reload_reg. In code to set new_spill_reg_store, use single_set to find out if there is a single set. Add code that allows to delete optional output reloads. Add code to allow deletion of output reloads that use no spill reg. At the end, set reload_override_in to oldequiv. Also call delete_output_reload if reload_out_reg is equal to old in oldequiv code. Add code to call delete_output_reload for stores with no matching load. Set / use spill_reg_stored_to. Handle case where secondary output reload uses a temporary, but actual store isn't found. When looking for a store of a value not loaded in order to call delete_output_reload, count_occurences should return 0 for no loads; but discount inherited input reloadill_reg_stored_to. Do checks for extra uses of REG. Changed all callers. Use delete_address_reloads. (reload): Take return value of find_reloads into account. If a no-op set needs more than one reload, delete it. (reload_reg_free_before_p): RELOAD_FOR_INPUT can ignore RELOAD_FOR_INPUT_ADDRESS / RELOAD_FOR_INPADDR_ADDRESS for the same operand. (clear_reload_reg_in_use): Check for other reloads that keep a register in use. (reload_reg_free_for_value_p): handle RELOAD_FOR_OPERAND_ADDRESS / RELOAD_FOR_OPADDR_ADDR. Take into account when an address address reload is only needed for the address reload we are considering.

Fix consistency problems with reg_equiv_{mem,address}; Improve reload inheritance; * reload.c (reload_out_reg): New variable. (loc_mentioned_in_p, remove_address_replacements): New functions. (remove_replacements): Deleted. (push_reload): Set reload_out_reg[i]. When merging, also set reload_{in,out}_reg[i], and remove duplicate address reloads. (combine_reloads): Copy reload_out_reg[i]. (find_reloads): Do make_memloc substitution also when reg_equiv_memory_loc[regno] and num_not_at_initial_offset are both nonzero. Include *recog_operand_loc in commutativity operand changes. Generate optional output reloads. Delete reference to n_memlocs. Don't set *recog_operand_loc before processing operands. Call make_memloc in reg_equiv_address code. Set *recog_operand_loc only after processing operands, and only if replace is true. Return a value. When changing address reload types for operands that didn't get reloaded, use RELOAD_FOR_OPADDR_ADDRESS for RELOAD_FOR_INPADDR_ADDRESS / RELOAD_FOR_OUTADDR_ADDRESS reloads. Don't emit USEs for pseudo SUBREGs when not replacing. (find_reloads_address): Do make_memloc substitution also when reg_equiv_memory_loc[regno] and num_not_at_initial_offset are both nonzero. (find_reloads_toplev): Likewise. Call make_memloc in reg_equiv_address code. (debug_reload_to_stream): Add code to output reload_out_reg. (make_memloc): Delete local variable i, ifdefed out code, and references to memlocs and n_memlocs. (memlocs, n_memlocs): Delete. (push_secondary_reload): Clear reload_out_reg. (find_reloads_address_1): Provide memrefloc argument to all calls to find_reloads_address. In AUTO_INC code, handle non-directly addressable equivalences properly. * reload.h (reload_out_reg, num_not_at_initial_offset): Declare. (find_reloads): Add return type. (remove_address_replacements, deallocate_reload_reg): Declare. * reload1.c (num_not_at_initial_offset): No longer static. (delete_address_reloads, delete_address_reloads_1): Likewise. (deallocate_reload_reg): New function. (spill_reg_stored_to): New array. (eliminate_regs): Don't substitute from reg_equiv_memory_loc. (eliminate_regs_in_insn): Move assignments of previous_offset and max_offset fields, and recalculation of num_not_at_initial_offset into new static function: (update_eliminable_offsets) . (reload_as_needed): Call update_eliminable_offsetss after calling find_reloads. Call forget_old_reloads_1 with contents of reloaded auto_inc expressions if the actual addressing can't be changed to match the auto_inc. (choose_reload_regs): For inheritance, replace reload_reg_free_before_p test with reload_reg_ions. (emit_reload_insns): If reload_in is a MEM, set OLD to reload_in_reg[j]. Don't reload directly from oldequiv; if it's a pseudo with a stack slot, use reload_in[j]. Check that reload_in_reg[j] is a MEM before replacing reload_in from reg_reloaded_contents. Include non-spill registers in reload inheritance processing. Also try to use reload_out_reg to set spill_reg_store / reg_last_reload_reg. In code to set new_spill_reg_store, use single_set to find out if there is a single set. Add code that allows to delete optional output reloads. Add code to allow deletion of output reloads that use no spill reg. At the end, set reload_override_in to oldequiv. Also call delete_output_reload if reload_out_reg is equal to old in oldequiv code. Add code to call delete_output_reload for stores with no matching load. Set / use spill_reg_stored_to. Handle case where secondary output reload uses a temporary, but actual store isn't found. When looking for a store of a value not loaded in order to call delete_output_reload, count_occurences should return 0 for no loads; but discount inherited input reloadill_reg_stored_to. Do checks for extra uses of REG. Changed all callers. Use delete_address_reloads. (reload): Take return value of find_reloads into account. If a no-op set needs more than one reload, delete it. (reload_reg_free_before_p): RELOAD_FOR_INPUT can ignore RELOAD_FOR_INPUT_ADDRESS / RELOAD_FOR_INPADDR_ADDRESS for the same operand. (clear_reload_reg_in_use): Check for other reloads that keep a register in use. (reload_reg_free_for_value_p): handle RELOAD_FOR_OPERAND_ADDRESS / RELOAD_FOR_OPADDR_ADDR. Take into account when an address address reload is only needed for the address reload we are considering. (count_occurrences): Use rtx_equal_p for MEMs. (inc_for_reload): Return instruction that stores into RELOADREG. New argument two, IN, and rtx. Changed all callers. (calculate_needs_all_insns, reload_as_needed): Don't clear after_call for a CLOBBER. Keep track of how many hard registers need to be copied from after_call, and don't clear after_call before we have seen that much copies, or we see a different instruction. From-SVN: r23143

(find_reloads): Do make_memloc substitution also when reg_equiv_memory_loc[regno] and num_not_at_initial_offset are both nonzero. Include *recog_operand_loc in commutativity operand changes. Generate optional output reloads. Delete reference to n_memlocs. Don't set *recog_operand_loc before processing operands. Call make_memloc in reg_equiv_address code. Set *recog_operand_loc only after processing operands, and only if replace is true. Return a value. When changing address reload types for operands that didn't get reloaded, use RELOAD_FOR_OPADDR_ADDRESS for RELOAD_FOR_INPADDR_ADDRESS / RELOAD_FOR_OUTADDR_ADDRESS reloads. Don't emit USEs for pseudo SUBREGs when not replacing. (find_reloads_address): Do make_memloc substitution also when reg_equiv_memory_loc[regno] and num_not_at_initial_offset are both nonzero. (find_reloads_toplev): Likewise. Call make_memloc in reg_equiv_address code. (debug_reload_to_stream): Add code to output reload_out_reg. (make_memloc): Delete local variable i, ifdefed out code, and references to memlocs and n_memlocs. (memlocs, n_memlocs): Delete. (push_secondary_reload): Clear reload_out_reg. (find_reloads_address_1): Provide memrefloc argument to all calls to find_reloads_address. In AUTO_INC code, handle non-directly addressable equivalences properly. * reload.h (reload_out_reg, num_not_at_initial_offset): Declare. (find_reloads): Add return type. (remove_address_replacements, deallocate_reload_reg): Declare. * reload1.c (num_not_at_initial_offset): No longer static. (delete_address_reloads, delete_address_reloads_1): Likewise. (deallocate_reload_reg): New function. (spill_reg_stored_to): New array. (eliminate_regs): Don't substitute from reg_equiv_memory_loc. (eliminate_regs_in_insn): Move assignments of previous_offset and max_offset fields, and recalculation of num_not_at_initial_offset into new static function: (update_eliminable_offsets) . (reload_as_needed): Call update_eliminable_offsetss after calling find_reloads. Call forget_old_reloads_1 with contents of reloaded auto_inc expressions if the actual addressing can't be changed to match the auto_inc. (choose_reload_regs): For inheritance, replace reload_reg_free_before_p test with reload_reg_ions. (emit_reload_insns): If reload_in is a MEM, set OLD to reload_in_reg[j]. Don't reload directly from oldequiv; if it's a pseudo with a stack slot, use reload_in[j]. Check that reload_in_reg[j] is a MEM before replacing reload_in from reg_reloaded_contents. Include non-spill registers in reload inheritance processing. Also try to use reload_out_reg to set spill_reg_store / reg_last_reload_reg. In code to set new_spill_reg_store, use single_set to find out if there is a single set. Add code that allows to delete optional output reloads. Add code to allow deletion of output reloads that use no spill reg. At the end, set reload_override_in to oldequiv. Also call delete_output_reload if reload_out_reg is equal to old in oldequiv code. Add code to call delete_output_reload for stores with no matching load. Set / use spill_reg_stored_to. Handle case where secondary output reload uses a temporary, but actual store isn't found. When looking for a store of a value not loaded in order to call delete_output_reload, count_occurences should return 0 for no loads; but discount inherited input reloadill_reg_stored_to. Do checks for extra uses of REG. Changed all callers. Use delete_address_reloads. (reload): Take return value of find_reloads into account. If a no-op set needs more than one reload, delete it. (reload_reg_free_before_p): RELOAD_FOR_INPUT can ignore RELOAD_FOR_INPUT_ADDRESS / RELOAD_FOR_INPADDR_ADDRESS for the same operand. (clear_reload_reg_in_use): Check for other reloads that keep a register in use. (reload_reg_free_for_value_p): handle RELOAD_FOR_OPERAND_ADDRESS / RELOAD_FOR_OPADDR_ADDR. Take into account when an address address reload is only needed for the address reload we are considering. (count_occurrences): Use rtx_equal_p for MEMs. (inc_for_reload): Return instruction that stores into RELOADREG. New argument two, IN, and rtx. Changed all callers. (calculate_needs_all_insns, reload_as_needed): Don't clear after_call for a CLOBBER. Keep track of how many hard registers need to be copied from after_call, and don't clear after_call before we have seen that much copies, or we see a different instruction. From-SVN: r23143

Merge cases of making optional reloads, avoid making output-only optional reloads, refine when we may not make in-out optional reloads, and make an optional reload for a pair of matching operands. (find_reloads_toplev, find_reloads_address{,_1, part}): Accept and use reload description. (forget_volatility): Delete long-obsolete function. From-SVN: r3911

We can easily check for an index needing reload, but even if that is the
case, we might also have an invalid constant. To avoid making the
conservative assumption and requiring two reloads, we see if this address
is valid when not interpreted strictly. If it is, the only problem is
that the index needs a reload and find_reloads_address_1 will take care
of it.

Fix consistency problems with reg_equiv_{mem,address}; Improve reload inheritance; * reload.c (reload_out_reg): New variable. (loc_mentioned_in_p, remove_address_replacements): New functions. (remove_replacements): Deleted. (push_reload): Set reload_out_reg[i]. When merging, also set reload_{in,out}_reg[i], and remove duplicate address reloads. (combine_reloads): Copy reload_out_reg[i]. (find_reloads): Do make_memloc substitution also when reg_equiv_memory_loc[regno] and num_not_at_initial_offset are both nonzero. Include *recog_operand_loc in commutativity operand changes. Generate optional output reloads. Delete reference to n_memlocs. Don't set *recog_operand_loc before processing operands. Call make_memloc in reg_equiv_address code. Set *recog_operand_loc only after processing operands, and only if replace is true. Return a value. When changing address reload types for operands that didn't get reloaded, use RELOAD_FOR_OPADDR_ADDRESS for RELOAD_FOR_INPADDR_ADDRESS / RELOAD_FOR_OUTADDR_ADDRESS reloads. Don't emit USEs for pseudo SUBREGs when not replacing. (find_reloads_address): Do make_memloc substitution also when reg_equiv_memory_loc[regno] and num_not_at_initial_offset are both nonzero. (find_reloads_toplev): Likewise. Call make_memloc in reg_equiv_address code. (debug_reload_to_stream): Add code to output reload_out_reg. (make_memloc): Delete local variable i, ifdefed out code, and references to memlocs and n_memlocs. (memlocs, n_memlocs): Delete. (push_secondary_reload): Clear reload_out_reg. (find_reloads_address_1): Provide memrefloc argument to all calls to find_reloads_address. In AUTO_INC code, handle non-directly addressable equivalences properly. * reload.h (reload_out_reg, num_not_at_initial_offset): Declare. (find_reloads): Add return type. (remove_address_replacements, deallocate_reload_reg): Declare. * reload1.c (num_not_at_initial_offset): No longer static. (delete_address_reloads, delete_address_reloads_1): Likewise. (deallocate_reload_reg): New function. (spill_reg_stored_to): New array. (eliminate_regs): Don't substitute from reg_equiv_memory_loc. (eliminate_regs_in_insn): Move assignments of previous_offset and max_offset fields, and recalculation of num_not_at_initial_offset into new static function: (update_eliminable_offsets) . (reload_as_needed): Call update_eliminable_offsetss after calling find_reloads. Call forget_old_reloads_1 with contents of reloaded auto_inc expressions if the actual addressing can't be changed to match the auto_inc. (choose_reload_regs): For inheritance, replace reload_reg_free_before_p test with reload_reg_ions. (emit_reload_insns): If reload_in is a MEM, set OLD to reload_in_reg[j]. Don't reload directly from oldequiv; if it's a pseudo with a stack slot, use reload_in[j]. Check that reload_in_reg[j] is a MEM before replacing reload_in from reg_reloaded_contents. Include non-spill registers in reload inheritance processing. Also try to use reload_out_reg to set spill_reg_store / reg_last_reload_reg. In code to set new_spill_reg_store, use single_set to find out if there is a single set. Add code that allows to delete optional output reloads. Add code to allow deletion of output reloads that use no spill reg. At the end, set reload_override_in to oldequiv. Also call delete_output_reload if reload_out_reg is equal to old in oldequiv code. Add code to call delete_output_reload for stores with no matching load. Set / use spill_reg_stored_to. Handle case where secondary output reload uses a temporary, but actual store isn't found. When looking for a store of a value not loaded in order to call delete_output_reload, count_occurences should return 0 for no loads; but discount inherited input reloadill_reg_stored_to. Do checks for extra uses of REG. Changed all callers. Use delete_address_reloads. (reload): Take return value of find_reloads into account. If a no-op set needs more than one reload, delete it. (reload_reg_free_before_p): RELOAD_FOR_INPUT can ignore RELOAD_FOR_INPUT_ADDRESS / RELOAD_FOR_INPADDR_ADDRESS for the same operand. (clear_reload_reg_in_use): Check for other reloads that keep a register in use. (reload_reg_free_for_value_p): handle RELOAD_FOR_OPERAND_ADDRESS / RELOAD_FOR_OPADDR_ADDR. Take into account when an address address reload is only needed for the address reload we are considering. (count_occurrences): Use rtx_equal_p for MEMs. (inc_for_reload): Return instruction that stores into RELOADREG. New argument two, IN, and rtx. Changed all callers. (calculate_needs_all_insns, reload_as_needed): Don't clear after_call for a CLOBBER. Keep track of how many hard registers need to be copied from after_call, and don't clear after_call before we have seen that much copies, or we see a different instruction. From-SVN: r23143

/* Find all pseudo regs appearing in AD
that are eliminable in favor of equivalent values
Fix consistency problems with reg_equiv_{mem,address}; Improve reload inheritance; * reload.c (reload_out_reg): New variable. (loc_mentioned_in_p, remove_address_replacements): New functions. (remove_replacements): Deleted. (push_reload): Set reload_out_reg[i]. When merging, also set reload_{in,out}_reg[i], and remove duplicate address reloads. (combine_reloads): Copy reload_out_reg[i]. (find_reloads): Do make_memloc substitution also when reg_equiv_memory_loc[regno] and num_not_at_initial_offset are both nonzero. Include *recog_operand_loc in commutativity operand changes. Generate optional output reloads. Delete reference to n_memlocs. Don't set *recog_operand_loc before processing operands. Call make_memloc in reg_equiv_address code. Set *recog_operand_loc only after processing operands, and only if replace is true. Return a value. When changing address reload types for operands that didn't get reloaded, use RELOAD_FOR_OPADDR_ADDRESS for RELOAD_FOR_INPADDR_ADDRESS / RELOAD_FOR_OUTADDR_ADDRESS reloads. Don't emit USEs for pseudo SUBREGs when not replacing. (find_reloads_address): Do make_memloc substitution also when reg_equiv_memory_loc[regno] and num_not_at_initial_offset are both nonzero. (find_reloads_toplev): Likewise. Call make_memloc in reg_equiv_address code. (debug_reload_to_stream): Add code to output reload_out_reg. (make_memloc): Delete local variable i, ifdefed out code, and references to memlocs and n_memlocs. (memlocs, n_memlocs): Delete. (push_secondary_reload): Clear reload_out_reg. (find_reloads_address_1): Provide memrefloc argument to all calls to find_reloads_address. In AUTO_INC code, handle non-directly addressable equivalences properly. * reload.h (reload_out_reg, num_not_at_initial_offset): Declare. (find_reloads): Add return type. (remove_address_replacements, deallocate_reload_reg): Declare. * reload1.c (num_not_at_initial_offset): No longer static. (delete_address_reloads, delete_address_reloads_1): Likewise. (deallocate_reload_reg): New function. (spill_reg_stored_to): New array. (eliminate_regs): Don't substitute from reg_equiv_memory_loc. (eliminate_regs_in_insn): Move assignments of previous_offset and max_offset fields, and recalculation of num_not_at_initial_offset into new static function: (update_eliminable_offsets) . (reload_as_needed): Call update_eliminable_offsetss after calling find_reloads. Call forget_old_reloads_1 with contents of reloaded auto_inc expressions if the actual addressing can't be changed to match the auto_inc. (choose_reload_regs): For inheritance, replace reload_reg_free_before_p test with reload_reg_ions. (emit_reload_insns): If reload_in is a MEM, set OLD to reload_in_reg[j]. Don't reload directly from oldequiv; if it's a pseudo with a stack slot, use reload_in[j]. Check that reload_in_reg[j] is a MEM before replacing reload_in from reg_reloaded_contents. Include non-spill registers in reload inheritance processing. Also try to use reload_out_reg to set spill_reg_store / reg_last_reload_reg. In code to set new_spill_reg_store, use single_set to find out if there is a single set. Add code that allows to delete optional output reloads. Add code to allow deletion of output reloads that use no spill reg. At the end, set reload_override_in to oldequiv. Also call delete_output_reload if reload_out_reg is equal to old in oldequiv code. Add code to call delete_output_reload for stores with no matching load. Set / use spill_reg_stored_to. Handle case where secondary output reload uses a temporary, but actual store isn't found. When looking for a store of a value not loaded in order to call delete_output_reload, count_occurences should return 0 for no loads; but discount inherited input reloadill_reg_stored_to. Do checks for extra uses of REG. Changed all callers. Use delete_address_reloads. (reload): Take return value of find_reloads into account. If a no-op set needs more than one reload, delete it. (reload_reg_free_before_p): RELOAD_FOR_INPUT can ignore RELOAD_FOR_INPUT_ADDRESS / RELOAD_FOR_INPADDR_ADDRESS for the same operand. (clear_reload_reg_in_use): Check for other reloads that keep a register in use. (reload_reg_free_for_value_p): handle RELOAD_FOR_OPERAND_ADDRESS / RELOAD_FOR_OPADDR_ADDR. Take into account when an address address reload is only needed for the address reload we are considering. (count_occurrences): Use rtx_equal_p for MEMs. (inc_for_reload): Return instruction that stores into RELOADREG. New argument two, IN, and rtx. Changed all callers. (calculate_needs_all_insns, reload_as_needed): Don't clear after_call for a CLOBBER. Keep track of how many hard registers need to be copied from after_call, and don't clear after_call before we have seen that much copies, or we see a different instruction. From-SVN: r23143

and do not have hard regs; replace them by their equivalents.
INSN, if nonzero, is the insn in which we do the reload. We put USEs in
front of it for pseudos that we have to replace with stack slots. */

= 0 means we are considering them as base regs.
OUTER_CODE is the code of the enclosing RTX, typically a MEM, a PLUS,
or an autoinc code.
If CONTEXT == 0 and OUTER_CODE is a PLUS or LO_SUM, then INDEX_CODE
is the code of the index part of the address. Otherwise, pass SCRATCH
for this argument.

(get_secondary_mem): Accept and use reload description (opnum and type). (push_reload): Accept and use new reload description instead of old NEEDED_FOR. Define two new macros: MERGEABLE_RELOADS and MERGE_TO_OTHER. Use these macros to see if reloads can be merged and how to do it. (transfer_replacements): New function. (combine_reloads): Refine when we can combine reloads. (find_reloads): Use new method of tracking what a reload is for. When we make a CLOBBER insn, do so with DImode. Merge cases of making optional reloads, avoid making output-only optional reloads, refine when we may not make in-out optional reloads, and make an optional reload for a pair of matching operands. (find_reloads_toplev, find_reloads_address{,_1, part}): Accept and use reload description. (forget_volatility): Delete long-obsolete function. From-SVN: r3911

OPNUM and TYPE specify the purpose of any reloads made.

IND_LEVELS says how many levels of indirect addressing are
supported at this point in the address.

INSN, if nonzero, is the insn in which we do the reload. It is used
to determine if we may generate output reloads.

Include non-spill registers in reload inheritance processing. Also try to use reload_out_reg to set spill_reg_store / reg_last_reload_reg.

Do checks for extra uses of REG. Changed all callers. Use delete_address_reloads. (reload): Take return value of find_reloads into account. If a no-op set needs more than one reload, delete it. (reload_reg_free_before_p): RELOAD_FOR_INPUT can ignore RELOAD_FOR_INPUT_ADDRESS / RELOAD_FOR_INPADDR_ADDRESS for the same operand.

Set *recog_operand_loc only after processing operands, and only if replace is true. Return a value. When changing address reload types for operands that didn't get reloaded, use RELOAD_FOR_OPADDR_ADDRESS for RELOAD_FOR_INPADDR_ADDRESS / RELOAD_FOR_OUTADDR_ADDRESS reloads.

(reload_as_needed): Call update_eliminable_offsetss after calling find_reloads. Call forget_old_reloads_1 with contents of reloaded auto_inc expressions if the actual addressing can't be changed to match the auto_inc. (choose_reload_regs): For inheritance, replace reload_reg_free_before_p test with reload_reg_ions. (emit_reload_insns): If reload_in is a MEM, set OLD to reload_in_reg[j]. Don't reload directly from oldequiv; if it's a pseudo with a stack slot, use reload_in[j]. Check that reload_in_reg[j] is a MEM before replacing reload_in from reg_reloaded_contents. Include non-spill registers in reload inheritance processing. Also try to use reload_out_reg to set spill_reg_store / reg_last_reload_reg. In code to set new_spill_reg_store, use single_set to find out if there is a single set. Add code that allows to delete optional output reloads. Add code to allow deletion of output reloads that use no spill reg. At the end, set reload_override_in to oldequiv. Also call delete_output_reload if reload_out_reg is equal to old in oldequiv code. Add code to call delete_output_reload for stores with no matching load. Set / use spill_reg_stored_to. Handle case where secondary output reload uses a temporary, but actual store isn't found. When looking for a store of a value not loaded in order to call delete_output_reload, count_occurences should return 0 for no loads; but discount inherited input reloadill_reg_stored_to. Do checks for extra uses of REG. Changed all callers. Use delete_address_reloads. (reload): Take return value of find_reloads into account. If a no-op set needs more than one reload, delete it. (reload_reg_free_before_p): RELOAD_FOR_INPUT can ignore RELOAD_FOR_INPUT_ADDRESS / RELOAD_FOR_INPADDR_ADDRESS for the same operand. (clear_reload_reg_in_use): Check for other reloads that keep a register in use. (reload_reg_free_for_value_p): handle RELOAD_FOR_OPERAND_ADDRESS / RELOAD_FOR_OPADDR_ADDR. Take into account when an address address reload is only needed for the address reload we are considering.

Fix consistency problems with reg_equiv_{mem,address}; Improve reload inheritance; * reload.c (reload_out_reg): New variable. (loc_mentioned_in_p, remove_address_replacements): New functions. (remove_replacements): Deleted. (push_reload): Set reload_out_reg[i]. When merging, also set reload_{in,out}_reg[i], and remove duplicate address reloads. (combine_reloads): Copy reload_out_reg[i]. (find_reloads): Do make_memloc substitution also when reg_equiv_memory_loc[regno] and num_not_at_initial_offset are both nonzero. Include *recog_operand_loc in commutativity operand changes. Generate optional output reloads. Delete reference to n_memlocs. Don't set *recog_operand_loc before processing operands. Call make_memloc in reg_equiv_address code. Set *recog_operand_loc only after processing operands, and only if replace is true. Return a value. When changing address reload types for operands that didn't get reloaded, use RELOAD_FOR_OPADDR_ADDRESS for RELOAD_FOR_INPADDR_ADDRESS / RELOAD_FOR_OUTADDR_ADDRESS reloads. Don't emit USEs for pseudo SUBREGs when not replacing. (find_reloads_address): Do make_memloc substitution also when reg_equiv_memory_loc[regno] and num_not_at_initial_offset are both nonzero. (find_reloads_toplev): Likewise. Call make_memloc in reg_equiv_address code. (debug_reload_to_stream): Add code to output reload_out_reg. (make_memloc): Delete local variable i, ifdefed out code, and references to memlocs and n_memlocs. (memlocs, n_memlocs): Delete. (push_secondary_reload): Clear reload_out_reg. (find_reloads_address_1): Provide memrefloc argument to all calls to find_reloads_address. In AUTO_INC code, handle non-directly addressable equivalences properly. * reload.h (reload_out_reg, num_not_at_initial_offset): Declare. (find_reloads): Add return type. (remove_address_replacements, deallocate_reload_reg): Declare. * reload1.c (num_not_at_initial_offset): No longer static. (delete_address_reloads, delete_address_reloads_1): Likewise. (deallocate_reload_reg): New function. (spill_reg_stored_to): New array. (eliminate_regs): Don't substitute from reg_equiv_memory_loc. (eliminate_regs_in_insn): Move assignments of previous_offset and max_offset fields, and recalculation of num_not_at_initial_offset into new static function: (update_eliminable_offsets) . (reload_as_needed): Call update_eliminable_offsetss after calling find_reloads. Call forget_old_reloads_1 with contents of reloaded auto_inc expressions if the actual addressing can't be changed to match the auto_inc. (choose_reload_regs): For inheritance, replace reload_reg_free_before_p test with reload_reg_ions. (emit_reload_insns): If reload_in is a MEM, set OLD to reload_in_reg[j]. Don't reload directly from oldequiv; if it's a pseudo with a stack slot, use reload_in[j]. Check that reload_in_reg[j] is a MEM before replacing reload_in from reg_reloaded_contents. Include non-spill registers in reload inheritance processing. Also try to use reload_out_reg to set spill_reg_store / reg_last_reload_reg. In code to set new_spill_reg_store, use single_set to find out if there is a single set. Add code that allows to delete optional output reloads. Add code to allow deletion of output reloads that use no spill reg. At the end, set reload_override_in to oldequiv. Also call delete_output_reload if reload_out_reg is equal to old in oldequiv code. Add code to call delete_output_reload for stores with no matching load. Set / use spill_reg_stored_to. Handle case where secondary output reload uses a temporary, but actual store isn't found. When looking for a store of a value not loaded in order to call delete_output_reload, count_occurences should return 0 for no loads; but discount inherited input reloadill_reg_stored_to. Do checks for extra uses of REG. Changed all callers. Use delete_address_reloads. (reload): Take return value of find_reloads into account. If a no-op set needs more than one reload, delete it. (reload_reg_free_before_p): RELOAD_FOR_INPUT can ignore RELOAD_FOR_INPUT_ADDRESS / RELOAD_FOR_INPADDR_ADDRESS for the same operand. (clear_reload_reg_in_use): Check for other reloads that keep a register in use. (reload_reg_free_for_value_p): handle RELOAD_FOR_OPERAND_ADDRESS / RELOAD_FOR_OPADDR_ADDR. Take into account when an address address reload is only needed for the address reload we are considering. (count_occurrences): Use rtx_equal_p for MEMs. (inc_for_reload): Return instruction that stores into RELOADREG. New argument two, IN, and rtx. Changed all callers. (calculate_needs_all_insns, reload_as_needed): Don't clear after_call for a CLOBBER. Keep track of how many hard registers need to be copied from after_call, and don't clear after_call before we have seen that much copies, or we see a different instruction. From-SVN: r23143

In AUTO_INC code, handle non-directly addressable equivalences properly. * reload.h (reload_out_reg, num_not_at_initial_offset): Declare. (find_reloads): Add return type. (remove_address_replacements, deallocate_reload_reg): Declare. * reload1.c (num_not_at_initial_offset): No longer static. (delete_address_reloads, delete_address_reloads_1): Likewise. (deallocate_reload_reg): New function. (spill_reg_stored_to): New array. (eliminate_regs): Don't substitute from reg_equiv_memory_loc. (eliminate_regs_in_insn): Move assignments of previous_offset and max_offset fields, and recalculation of num_not_at_initial_offset into new static function: (update_eliminable_offsets) . (reload_as_needed): Call update_eliminable_offsetss after calling find_reloads. Call forget_old_reloads_1 with contents of reloaded auto_inc expressions if the actual addressing can't be changed to match the auto_inc. (choose_reload_regs): For inheritance, replace reload_reg_free_before_p test with reload_reg_ions. (emit_reload_insns): If reload_in is a MEM, set OLD to reload_in_reg[j]. Don't reload directly from oldequiv; if it's a pseudo with a stack slot, use reload_in[j]. Check that reload_in_reg[j] is a MEM before replacing reload_in from reg_reloaded_contents. Include non-spill registers in reload inheritance processing. Also try to use reload_out_reg to set spill_reg_store / reg_last_reload_reg. In code to set new_spill_reg_store, use single_set to find out if there is a single set. Add code that allows to delete optional output reloads. Add code to allow deletion of output reloads that use no spill reg. At the end, set reload_override_in to oldequiv. Also call delete_output_reload if reload_out_reg is equal to old in oldequiv code. Add code to call delete_output_reload for stores with no matching load. Set / use spill_reg_stored_to. Handle case where secondary output reload uses a temporary, but actual store isn't found. When looking for a store of a value not loaded in order to call delete_output_reload, count_occurences should return 0 for no loads; but discount inherited input reloadill_reg_stored_to. Do checks for extra uses of REG. Changed all callers. Use delete_address_reloads. (reload): Take return value of find_reloads into account. If a no-op set needs more than one reload, delete it. (reload_reg_free_before_p): RELOAD_FOR_INPUT can ignore RELOAD_FOR_INPUT_ADDRESS / RELOAD_FOR_INPADDR_ADDRESS for the same operand. (clear_reload_reg_in_use): Check for other reloads that keep a register in use. (reload_reg_free_for_value_p): handle RELOAD_FOR_OPERAND_ADDRESS / RELOAD_FOR_OPADDR_ADDR. Take into account when an address address reload is only needed for the address reload we are considering. (count_occurrences): Use rtx_equal_p for MEMs. (inc_for_reload): Return instruction that stores into RELOADREG. New argument two, IN, and rtx. Changed all callers. (calculate_needs_all_insns, reload_as_needed): Don't clear after_call for a CLOBBER. Keep track of how many hard registers need to be copied from after_call, and don't clear after_call before we have seen that much copies, or we see a different instruction. From-SVN: r23143

/* Check the insns before INSN to see if there is a suitable register
containing the same value as GOAL.
If OTHER is -1, look for a register in class CLASS.
Otherwise, just see if register number OTHER shares GOAL's value.
Return an rtx for the register found, or zero if none is found.
If RELOAD_REG_P is (short *)1,
we reject any hard reg that appears in reload_reg_rtx
because such a hard reg is also needed coming into this insn.
If RELOAD_REG_P is any other nonzero value,
it is a vector indexed by hard reg number
and we reject any hard reg whose element in the vector is nonnegative
as well as any that appears in reload_reg_rtx.
If GOAL is zero, then GOALREG is a register number; we look
for an equivalent for that register.
MODE is the machine mode of the value we want an equivalence for.
If GOAL is nonzero and not VOIDmode, then it must have mode MODE.
This function is used by jump.c as well as in the reload pass.
If GOAL is the sum of the stack pointer and a constant, we treat it
as if it were a constant except that sp is required to be unchanging. */

(combine_reloads): Refine when we can combine reloads. (find_reloads): Use new method of tracking what a reload is for. When we make a CLOBBER insn, do so with DImode. Merge cases of making optional reloads, avoid making output-only optional reloads, refine when we may not make in-out optional reloads, and make an optional reload for a pair of matching operands. (find_reloads_toplev, find_reloads_address{,_1, part}): Accept and use reload description. (forget_volatility): Delete long-obsolete function. From-SVN: r3911

Fix consistency problems with reg_equiv_{mem,address}; Improve reload inheritance; * reload.c (reload_out_reg): New variable. (loc_mentioned_in_p, remove_address_replacements): New functions. (remove_replacements): Deleted. (push_reload): Set reload_out_reg[i]. When merging, also set reload_{in,out}_reg[i], and remove duplicate address reloads. (combine_reloads): Copy reload_out_reg[i]. (find_reloads): Do make_memloc substitution also when reg_equiv_memory_loc[regno] and num_not_at_initial_offset are both nonzero. Include *recog_operand_loc in commutativity operand changes. Generate optional output reloads. Delete reference to n_memlocs. Don't set *recog_operand_loc before processing operands. Call make_memloc in reg_equiv_address code. Set *recog_operand_loc only after processing operands, and only if replace is true. Return a value. When changing address reload types for operands that didn't get reloaded, use RELOAD_FOR_OPADDR_ADDRESS for RELOAD_FOR_INPADDR_ADDRESS / RELOAD_FOR_OUTADDR_ADDRESS reloads. Don't emit USEs for pseudo SUBREGs when not replacing. (find_reloads_address): Do make_memloc substitution also when reg_equiv_memory_loc[regno] and num_not_at_initial_offset are both nonzero. (find_reloads_toplev): Likewise. Call make_memloc in reg_equiv_address code. (debug_reload_to_stream): Add code to output reload_out_reg. (make_memloc): Delete local variable i, ifdefed out code, and references to memlocs and n_memlocs. (memlocs, n_memlocs): Delete. (push_secondary_reload): Clear reload_out_reg. (find_reloads_address_1): Provide memrefloc argument to all calls to find_reloads_address. In AUTO_INC code, handle non-directly addressable equivalences properly. * reload.h (reload_out_reg, num_not_at_initial_offset): Declare. (find_reloads): Add return type.

(eliminate_regs_in_insn): Move assignments of previous_offset and max_offset fields, and recalculation of num_not_at_initial_offset into new static function: (update_eliminable_offsets) . (reload_as_needed): Call update_eliminable_offsetss after calling find_reloads. Call forget_old_reloads_1 with contents of reloaded auto_inc expressions if the actual addressing can't be changed to match the auto_inc. (choose_reload_regs): For inheritance, replace reload_reg_free_before_p test with reload_reg_ions. (emit_reload_insns): If reload_in is a MEM, set OLD to reload_in_reg[j]. Don't reload directly from oldequiv; if it's a pseudo with a stack slot, use reload_in[j]. Check that reload_in_reg[j] is a MEM before replacing reload_in from reg_reloaded_contents. Include non-spill registers in reload inheritance processing. Also try to use reload_out_reg to set spill_reg_store / reg_last_reload_reg. In code to set new_spill_reg_store, use single_set to find out if there is a single set. Add code that allows to delete optional output reloads. Add code to allow deletion of output reloads that use no spill reg. At the end, set reload_override_in to oldequiv. Also call delete_output_reload if reload_out_reg is equal to old in oldequiv code. Add code to call delete_output_reload for stores with no matching load. Set / use spill_reg_stored_to. Handle case where secondary output reload uses a temporary, but actual store isn't found. When looking for a store of a value not loaded in order to call delete_output_reload, count_occurences should return 0 for no loads; but discount inherited input reloadill_reg_stored_to. Do checks for extra uses of REG. Changed all callers. Use delete_address_reloads. (reload): Take return value of find_reloads into account. If a no-op set needs more than one reload, delete it. (reload_reg_free_before_p): RELOAD_FOR_INPUT can ignore RELOAD_FOR_INPUT_ADDRESS / RELOAD_FOR_INPADDR_ADDRESS for the same operand. (clear_reload_reg_in_use): Check for other reloads that keep a register in use. (reload_reg_free_for_value_p): handle RELOAD_FOR_OPERAND_ADDRESS / RELOAD_FOR_OPADDR_ADDR. Take into account when an address address reload is only needed for the address reload we are considering. (count_occurrences): Use rtx_equal_p for MEMs. (inc_for_reload): Return instruction that stores into RELOADREG. New argument two, IN, and rtx. Changed all callers. (calculate_needs_all_insns, reload_as_needed): Don't clear after_call for a CLOBBER. Keep track of how many hard registers need to be copied from after_call, and don't clear after_call before we have seen that much copies, or we see a different instruction. From-SVN: r23143
