Deleted dependencies on some header files.
Replaced the use of the functions from memory.h with funtions like bzero.
Changed the include format.
From-SVN: r2019
-mpa-risc-1-0, -mpa-risc-1-1.
(ASM_DECLARE_FUNCTION_NAME): Emit argument descriptors for all
general registers if current_function_varargs.
From-SVN: r2018
(expand_fixup): Create a BLOCK node (via pushlevel/poplevel)
to represent an artificial scope containing all of the fixup code.
Also emit NOTE_INSN_BLOCK_BEG/NOTE_INSN_BLOCK_END for that block.
(fixup_gotos): Declaration of NEWBLOCK deleted.
Call `set_block' to use the BLOCK made in expand_fixup.
Deleted code to insert NEWBLOCK into block hierarchy.
From-SVN: r2014
(sched_analyze_2): Remove an explicit dependence between an insn
that uses CC0 and the immediately previous insn.
(SCHED_GROUP_P represents the dependence.)
(schedule_block): Only check sets_cc0_p on an insn.
From-SVN: r2010
(read_specs): Clear the entire new element of compilers.
(lookup_compiler): Copy all of spec array. Check element 0 for @.
(main): Concatenate all elements of compiler spec.
(validate_all_switches): Validate from all elements of compiler spec.
(default_compilers): Split CPP commands into separate strings.
From-SVN: r2005
* caller-save.c (restore_referenced_regs): When restoring a
referenced hard register, use CEIL instead of truncating
divide to determine the maximum number of registers to
restore.
(insert_save_restore): Document maxrestore parameter.
(CEIL): Define.
From-SVN: r2003
(TARGET_SWITCHES): Add "no-80387", "no-soft-float", "fp-ret-in-387", and
"no-fp-ret-in-387".
Change no* switches to no-*.
(CONDITIONAL_REGISTER_USAGE): Make 387 regs fixed if the 387 is not used
at all.
(REG_CLASS_FROM_LETTER): Constraint letters 'f', 't' and 'u' are NO_REGS
if the 387 is not used.
(TRAMPOLINE_TEMPLATE): Use GEN_INT to generate const_int rtx.
From-SVN: r2001
(TARGET_DEFAULT,VALUE_REGNO,FUNCTION_VALUE_REGNO): Moved from unix target
files (aix386.h, i386gas.h, i386sun.h, i386v.h, i386v4.h, i386vgas.h,
seq386.h).
(TARGET_DEFAULT): Make TARGET_IEEE_FP default on.
(VALUE_REGNO): Test for MODE_FLOAT instead of specific modes.
(VALUE_REGNO,FUNCTION_VALUE_REGNO): MODE_FLOAT return reg depends on
TARGET_FLOAT_RETURNS_IN_80387.
From-SVN: r2000
(save_for_inline_copying): When making copies of NOTE_INSN_BLOCK_END
notes, stash a "forwarding" pointer in the original to point to the
copy. Also, when all BLOCKs & insns for a function have been copied,
call `adjust_copied_decl_tree' to fixup the end_note pointers in the
copied BLOCKs.
From-SVN: r1991
(remember_end_note): New function.
(expand_end_bindings): Save NOTE_INSN_BLOCK_END in last_block_end_note.
(struct goto_fixup): New field context.
(fixup_cleanups): Function deleted.
(fixup_gotos): Put the fixup in a block, and put that block
into its proper place. Use sequences, not reorder_insns.
From-SVN: r1990
Avoid double-negative "! NON_*" constructs for clarity.
Pass NULL_PTR as null parameter instead of 0.
(sqrtM2): Patterns are only valid if IEEE FP or -ffast-math.
(sinM2,cosM2): New patterns.
(zero_extract test): New pattern.
From-SVN: r1982
(record_reg_life_pat): Rewrite to handle any sort of pattern.
(record_reg_life): Change interface to record_reg_life_pat.
(stack_reg_life_analysis): Don't assume that MODE_FLOAT values are
always returned in a float reg.
(subst_stack_regs_pat): Add support for sin and cos insns.
From-SVN: r1980
