* Makefile.in (gcc.o): Depend upon config.status, so any changes
in prefix will be communicated to the build process.
(cccp.o): Likewise.
From-SVN: r3407
(parser_build_binary_op): Warn about overflows and
conversions of out-of-range constants in parser-built binary expressions.
(build_conditional_expr): Check conversions in if-then-else expressions.
(build_c_cast): Ignore any integer overflow caused by a cast.
(convert_for_assignment): Warn if source had overflow in folding.
(process_init_constructor): Report overflows in array initializer indexes.
From-SVN: r3404
(lshift_double): Don't report arithmetic overflow, since the
C standard doesn't seem to require it here.
(force_fit_type): Accept new parameter specifying whether a signed
overflow has already occurred. Yield overflow indication.
All callers changed.
(neg_double): Don't report overflow when -0 yields 0.
(const_binop): Propagate operand overflow for warnings.
Don't report overflow when -1 + 1 yields 0.
From-SVN: r3401
(cmpXf insns): Allow 0.0 for either operand of the
comparison. Update output template to handle 0.0 as one
of the operands.
(movsi insn, fp->fp case): Update constraints and template to
allow store of zero into an FP register.
(movhi insn, fp->fp case): Likewise.
(movqi insn, fp->fp case): Likewise.
(movdi insn, fp->fp case): Likewise.
(movDF const_double pattern): Do not apply this pattern
if the const_double is zero.
(movdf insn, fp->fp and gr->gr cases): Update constraints
and output template to allow store of zero into a FP or GR.
Update condition string to allow zero as operand 1.
(movsf insn, fp->fp and gr->gr cases): Likewise. Also allow
store of zero into a memory location.
From-SVN: r3393
* pa.h (CONST_DOUBLE_OK_FOR_LETTER_P): Generalize.
(LEGITIMATE_CONSTANT_P): Allow 0.0.
(CONST_COSTS, case CONST_DOUBLE): fp0.0 is free when
not used in a SET expression.
From-SVN: r3392
* pa.c (reg_or_0_operand): Use CONST0_RTX instead of
const0_rtx.
(reg_or_0_or_nonsymb_mem_operand): New function.
(emit_move_sequence): Copying CONST0_RTX into any
register can be done directly. Use CONST0_RTX instead
of const0_rtx.
(output_fp_move_double): Handle copying a CONST0_RTX
into FP or integer registers.
(print_operand): Handle "%r0" for DFmode and SFmode
values too.
From-SVN: r3391
* c-common.c (c_build_type_variant): Moved here from c-decl.c.
Redirected the TYPE_MAIN_VARIANT to the "real" main variant.
Build the possibly new array type on the permanent obstack if it
the original type was permanent.
(permanent_obstack): Added extern declaration.
From-SVN: r3388
* reload.c (find_reloads_toplev): When handling a (subreg (reg))
where (reg) will be replaced by a memory reference, if the memory
address is invalid for the mode of the subreg, then search the
memory address for reloads.
From-SVN: r3385
* pa.md (iorsi3): Split into two patterns, a named "iorsi3" which
only accepts registers, and a combiner pattern which accepts a
restricted set of constant integers for one term.
From-SVN: r3382
