(simplify_binary_operation, fold_rtx): Allow some FP simplications
with -ffast-math.
(simplify_relational_operation): FP comparisons can be reversed
if -ffast-math is specified.
From-SVN: r6334
(fold_rtx, case PLUS): If we have (plus A B), A is equivalent to a
negative constant, and the negated constant is in register, convert to
(minus A C) where C is the register containing the negated constant.

* pa.h (DBX_BLOCKS_FUNCTION_RELATIVE): Define.
(ASM_OUTPUT_SOURCE_LINE): Likewise.
(DBX_FUNCTION_FIRST): Likewise.
* pa.h (FRAME_POINTER_REGNUM, ARG_POINTER_REGNUM): Change to %r3
for compatability with HP compilers.
* pa.h (READONLY_DATA_SECTION): Re-enable use of $LIT$.
From-SVN: r6325
(fold, case EQ_EXPR, NE_EXPR): If COMPLEX_TYPE and at least one arg is
a COMPLEX_EXPR, split into a logical operation on the real and
imaginary parts.
From-SVN: r6313
(common_type): For COMPLEX_TYPE, return one of the original types if is the
desired common type.
(build_binary_op): Use SHORT_COMPARE code even if complex.
From-SVN: r6312
New functions.
(struct file_name_list): New members: name_map, got_name_map.
(main, path_include, do_include, do_once): Set got_name_map.
(do_include): Use open_include_file instead of open. Add new
parameter to lookup_import calls.
(lookup_import): New parameter searchptr. Call open_include_file
instead of open.
From-SVN: r6307
* cse.c (cse_insn): Set "cse_jumps_altered" when collapsing
a switch statement into an unconditional jump.
* toplev.c (rest_of_compilation): Rerun jump_optimize
before the second CSE pass.
From-SVN: r6305
(push_reload, find_reloads): Reload inside a paradoxical SUBREG of MEM
except don't force a reload unless the inner mode is narrower than
BIGGEST_ALIGNMENT.
From-SVN: r6302
(decl_attribute): Verify that alignment and format argument numbers are all
integer constants.
Continue on to next attribute if one is in error.
From-SVN: r6300
(simplify_binary_operation): Can fold multi-word operations when first is
CONST_INT.
(simplify_binary_operation, case PLUS, MINUS): Don't call plus_constant when
OP0 is VOIDmode.
From-SVN: r6298
2 new recognizers for sub;subb. 1 new recognizer for addi;subb.
(movstrsi): Remove predicates. Set inline threshold to 8.
(umulsidi3): Change predicates to nonimmediate_operand.
New recognizer for multiply-by-immediate.
(andsi3): Add `!' for register alternative.
(vdepi_ior, vdepi_and): New recognizers.
(vextru rx,1,ry, vextrs rx,1,ry): New recognizers.
(call, call_value): If PIC, emit USE for for
PIC_OFFSET_TABLE_REGNUM. Use PIC_OFFSET_TABLE_REGNUM rather than 19.
From-SVN: r6294
(uint32_operand): New function.
(output_block_move): Change unroll threshold from 64 to 32.
(compute_movstrsi_length): Corresponding change.
(print_operand): Don't call debug_rtx, just abort.
(initialize_pic): Delete.
(finalize_pic): Use PIC_OFFSET_TABLE_REGNUM rather than 19.
