(sCC patterns): Use %char notation instead of nested if stmts.
(branch matchers): Likewise.
(incscc, negscc): Likewise. Add ? constraint for 3-insn alternative.
(incscc): Split into `incscc' and `decscc' to make this really
match.
(incscc/decscc special cases): New patterns using carry bit.
(many patterns): Use canonical address format. Use %r
register notation. Use GEN_INT.
(main move SF recognizer): Allow 0 for copying to general register.
(zero_extendhisi2): Remove DEFINE_EXPAND.
(zero_extendqihi2): Likewise.
(zero_extendqisi2): Likewise.
(comment before sign extension): Remove the lie.
From-SVN: r3278
(make_signed_type): Consistently use
HOST_BITS_PER_WIDE_INT. Correct minor formatting problems.
(fixup_signed_type): Use HOST_BITS_PER_WIDE_INT and HOST_WIDE_INT
like make_signed_type does.
(fixup_unsigned_type): Correct minor formatting problem.
From-SVN: r3263
* pa.h (FP_REG_CLASS_P): New macro.
(REGISTER_MOVE_COST): Use FP_REG_CLASS_P to simplify. Make
copies from the SAR so expensive that they should never happen.
From-SVN: r3259
(compute_zdepi_operands): Fix header comment.
(many functions): Use %%r register syntax. Use canonical (0,%rN)
address format.
(output_function_prologue): No need to test frame_pointer_needed
in else clause of `if (frame_pointer_needed)'.
(output_function_prologue): Test boolean merge_sp_adjust_with_store
for zeroness, not for equality with 1.
(fmpyaddoperands): Use new variable mode for mode of operands[0].
(fmpysuboperands): Likewise.
From-SVN: r3258
* c-decl.c (c_decode_option): Set WARN_UNINITIALIZED to 2 with
-Wall, being careful to preserve it if it's already set.
* cp-decl2.c (lang_decode_option): Likewise.
* toplev.c (main): Warn about using -Wuninitialized without -O.
From-SVN: r3250
* gcc.c (process_command): Only accept input files which exist and
can be read; prevent link phase if an input file was rejected.
(error_count): Make into a static global variable.
From-SVN: r3249
* pa.c (output_function_prologue): Combine stack adjustment and
first GR save when reasonable to do so.
(output_function_epilogue): Combine stack adjustment and first
GR restore when reasonable to do so. Avoid load/use stall for
RP restore in common cases.
From-SVN: r3246
(CONST_OK_FOR_LETTER_P): Change meaning of 'K'. Add new
alternative 'N'. Use VAL_*_BITS_P macros when possible.
(LEGITIMATE_CONSTANT_P) Fix comment.
(FITS_14_BITS): Remove.
(SMALL_INT): Remove.
From-SVN: r3241
(move_operand): Allow all CONST_INTs that can be moved to
general registers with one insn.
(pre_cint_operand): New predicate for predecrementing ldwm/stwm insns.
(zdepi_cint_p): New function.
(depi_cint_operand): Remove.
(and_mask_p): New name for consec_zeros_p. All callers changed.
(srcsi_operand): Removed.
(all file): Use INT_14_BITS instead of synonym SMALL_INT.
(emit_move_sequence): Clean up CONST_INT case.
(compute_zdepi_operands): New name for
compute_xdepi_operands_from_integer. Change second parm to return
plain integers (was RTXes).
(print_operand): Handle 'Z' for 'zdepi' source used to movCONST_INT.
