(pushdecl): Internally generated vars can be
detected with DECL_SOURCE_LINE of zero, not DECL_IGNORED_P.
(start_enum): Push obstacks, switch to permanent if global.
(finish_enum): Pop obstacks.
(store_parm_decls): When clearing ->names, clear out the values
from the identifiers, restore shadowed values, and clear ->shadowed.
(grokdeclarator): Don't warn of const or volatile function
in a system header file.
(start_struct): Push the obstacks.
Switch to permanent if at top level.
(finish_struct): Pop them.
(store_parm_decls): If we have (erroneously) a prototype
and old-style parm decls, throw away the old-style parm decls.
(finish_decl): Do the pop_obstacks sooner, when it's
time to start allocating in the ambient context's obstack.
Don't call permanent_allocation unless got back to permanent obstack.
(explicit_flag_signed_bitfields): New variable.
(c_decode_option): Set that for -f[un]signed-bitfields.
(grokdeclarator): If that's set, and -fsigned-bitfields,
disregard -traditional when handling bitfield signedness.

(PRINT_REG): Default definition added.
(dwarf_last_decl): Variable declaration added.
(output_reg_number): New function; handle -fverbose-asm reg printing.
(output_mem_loc_descriptor, output_loc_descriptor): Call it.
(output_decl): Set `dwarf_last_decl' each time this fn is called.
From-SVN: r2325
(expand_expr): For ABS_EXPR, give expand_unop the operand's mode.
(expand_expr): For REALPART_EXPR, IMAGPART_EXPR, just return that part.

Catch cases of bogus DECL_RTL values involving pseudo-regs (for all
target systems) and print an annoying message if we ever see such a case.
From-SVN: r2311
(reload): Move test for failure to find any group
to after the loop over i. Also check that all the regnos fit
below FIRST_PSEUDO_REGISTER.
From-SVN: r2306
(SECONDARY_INPUT_RELOAD_CLASS): Also need a temp reg
when loading HImode and QImode values from memory to FP_REGS.
(SECONDARY_OUTPUT_RELOAD_CLASS): New macro. Define this to handle
HImode and QImode stores from FP_REGS to memory similar to above.

* pa.md (add high part and dp register): Split into two patterns,
one for normal code, one for kernels. Kernel version only allows
"r1" as the destination register.
From-SVN: r2298
* pa.h (LEGITIMIZE_ADDRESS, SYMBOL_REF case): Emit a sequence
which will cause "addil" instructions to be emitted instead of
"ldil; add" sequences.
* pa.h (TARGET_KERNEL): New switch "-mkernel" which forces gcc to
avoid "ldil; add" sequences with %r27 and instead generate "addil"
sequences. This avoids a HPUX linker bug when compiling kernels.
From-SVN: r2297
* pa.c (emit_move_sequence): When making a reference to the data
space before reload, emit an insn sequence which is much more
likely to create "addil" instructions rather than "ldil; add"
sequences. Doing so greatly reduces the chance of running into a
HPUX linker bug when compiling kernels.
