(default_compilers): Add missing comma between strings, so
that traditional compilers can compile gcc.c.
(main): Don't pass strcpy or strlen a NULL pointer if some of the
spec strings in default_compilers are NULL.
(validate_all_switches): Don't dereference a NULL pointer if some of
the spec strings in defalut_compilers are NULL.
From-SVN: r2039
* caller-save.c (init_caller_save): If we were unable to
find a simple insn which meets all its constraints to save
and restore with a single insn in a mode, then set
regno_save_mode to VOIDmode to insure that this mode is never
used to caller-save the current register.
From-SVN: r2038
(make_compound_operation, case ASHIFTRT): Add new code to
handle (ashiftrt (neg (ashift FOO C1) C2)) just like we currently
handle (ashiftrt (OP (ashiftrt FOO C1) C2) C2).
From-SVN: r2028
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.
