(fold): If moved conversion into COND_EXPR, leave it there if it is an
integral conversion to word or narrower.
(fold, case NOP_EXPR): Ignore conversion to same type as operand.
(fold, case COND_EXPR): Make third operand the simplest.
From-SVN: r8467
(store_expr): If don't want a value and storing into promoted
variable, do conversion at tree level; don't copy volatile MEM unless
want value, as comment says.
From-SVN: r8466
(FUNCTION_VALUE): Use
POINTER_TYPE_P rather than checking the type against POINTER_TYPE
(to include references).
Don't define __PTR_TO_INT and
__INT_TO_PTR.
From-SVN: r8453
(relax_delay_slots): When invert a conditional jump over a single
unconditional jump, invert the INSN_FROM_TARGET_P bit of insns in the
delay slots.
From-SVN: r8452
(specs, float.h-cross, xlimits.h): Use temporary instead of redirecting
output directly to make target.
($(MD_FILE), xsys-protos.h): Likewise.
(mostlyclean): Remove any of these temporaries.
From-SVN: r8450
(redundant_insn_p): Change return type to rtx. Return the redundant insn
instead of true.
(update_reg_unused_notes): New function.
(fill_slots_from_thread): Call update_reg_unused_notes after one of the
redundant_insn_p calls.
From-SVN: r8446
* pa.c (output_cbranch): Improve code for short backwards branch
with an unfilled delay slot.
(output_bb, output_dbra, output_movb): Likewise.
From-SVN: r8441
(find_basic_blocks): Call it to physically delete insns in
unreachable blocks. When scanning blocks after dead ones,
start scanning after the dead one (not at the dead one).
If there are lots of unreachable blocks, make another pass to squeeze
them out (this reduces memory usage in some pathalogical cases by a
significant amount without resorting to sparse matrices).
(propagate_block): Make code a bit more efficient (for example,
no need to test `loop_depth' for each insn, just notes).
From-SVN: r8440
* config/pa/x-pa (TAROUTOPTS): Delete. It was an HPUX host
conditional, and x-pa is a BSD host target fragment.
(INSTALL_HEADERS): Define.
(STMP_FIXPROTO): Define.
From-SVN: r8436
* config/pa/pa-hiux.h: Include "pa/pa-hpux.h" and just override
the CPP predefines.
(CPP_PREDEFINES): Add -A assertions.
* config/pa/{pa1-hiux.h, pa-ghiux.h, pa1-ghiux.h}: Likewise.

Fixes for NextStep 3.2. Remove ``__const__'' from sin and cos
prototypes in ansi/math.h. Remove keyword ``template'' from
bfd/libc.h. Remove ``volatile'' from abort in bsd/libc.h and abort
and exit in ansi/stdlib.h.
From-SVN: r8434
(FUNCTION_PROFILER): Move down to make file more similar to netbsd-i386.h.
(DEFAULT_TARGET_MACHINE, etc): Comment our this braindamage!
