* reorg.c: (mark_referenced_resource): if frame_pointer_needed,
HARD_FRAME_POINTER_REGNUM is also a referenced resource.
(mark_target_live_regs): value in HARD_FRAME_POINTER_REGNUM is not
call-clobbered.
(dbr_schedule): HARD_FRAME_POINTER_REGNUM should be valid at the
end of a function.
From-SVN: r5464
* reload1.c: (init_reload): use HARD_FRAME_POINTER_REGNUM instead of
FRAME_POINTER_REGNUM.
(reload): Only prohibit elimination of HARD_FRAME_POINTER_REGNUM, not
FRAME_POINTER_REGNUM if frame_pointer_needed. Never prohibit
elimination of FRAME_POINTER_REGNUM into HARD_FRAME_POINTER_REGNUM.
Mark HARD_FRAME_POINTER_REGNUM as live at the start of a block if
it is still needed after elimination.
(eliminate_regs): For non-local goto's, don't delete stores into the
hard frame pointer.
(eliminate_regs_in_insn): adjust comment.
(mark_not_eliminable): if frame_pointer_rtx and hard_frame_pointer_rtx
are not the same, then frame_pointer_rtx is eliminable;
hard_frame_pointer_rtx never is if it is set..
(order_regs_for_reload): HARD_FRAME_POINTER_REGNUM is a bad spill reg.
(choose_reload_regs): HARD_FRAME_POINTER_REGNUM is a bad choice.
From-SVN: r5463
* reload.c: (immune_p): Constants never overlap hard frame pointer references.
(find_reloads_address): Compute invalid references to the hard
frame pointer in a register; also (reg + const)
and (reg + reg + const).
From-SVN: r5462
* flow.c: (life_analysis): Mark HARD_FRAME_POINTER_REGNUM as live at
the end of the function.
(insn_dead_p): Don't delete insns that set the hard frame pointer.
(mark_set_1): Don't add death information about
HARD_FRAME_POINTER_REGNUM.
(mark_used_regs, case REG): Don't put HARD_FRAME_POINTER_REGNUM in
regs_ever_live. Don't mark it as needed either.
* function.c: (instantiate_virtual_regs_1, case MEM): references to
MEM via the hard frame pointer shouldn't be copied.
From-SVN: r5455
* cse.c: (FIXED_REGNO_P): HARD_FRAME_POINTER_REGNUM is fixed.
(CHEAP_REG): HARD_FRAME_POINTER_REGNUM is cheap.
(FIXED_BASE_PLUS): Allow hard frame pointer as base.
(NONZERO_BASE_PLUS_P): Likewise.
(cannon_hash, case REG): Add HARD_FRAME_POINTER_REGNUM to list of
special registers for SMALL_REGISTER_CLASSES.
(find_best_addr): Addresses containing HARD_FRAME_POINTER_REGNUM
cannot be replaced.
(cse_main): value in HARD_FRAME_POINTER_REGNUM is preserved across calls.
From-SVN: r5451
* combine.c: (combinable_i3_pat): Don't add REG_DEAD notes for
HARD_FRAME_POINTER_REGNUM.
(subst, case SUBREG): Don't change register number or mode if it
is HARD_FRAME_POINTER_REGNUM.
From-SVN: r5450
(eliminate_regs): Specially handle the case where INSN
is a note (an EXPR_LIST or INSN_LIST).
(eliminate_regs_in_insn): Pass the notes as INSN,
when calling eliminate_insn to process the notes.
From-SVN: r5445
Add bi-parser.h as target.
Put these files in srcdir.
(bc-optab.o, bc-emit.o): Add missing deps.
(bi-parser.c, bi-lexer.c): Don't depend on .h files here.
From-SVN: r5442
(combine_instructions): Use it.
(force_to_mode): Narrow mask to fit mode (except VOIDmode).
(record_value_for_reg): When zeroing reg_last_set_value, also
zero reg_last_set_{mode,nonzero_bits,sign_bit_copies}.
(record_dead_and_set_regs): Likewise.
From-SVN: r5430
(build_c_cast): When making a CONSTRUCTOR for a union cast,
specify its type.
(default_conversion): Implement -fallow-single-precision.
