(fold, case *_DIV_EXPR): Replace code to handle (A*C1)/C2 with more general
code to handle addition as well.
(fold, case *_MOD_EXPR): Add simplified version of above code.
From-SVN: r4757
(init_decl_processing): When making SIZETYPE, start with name in
SIZE_TYPE. If -traditional, use a signed version of that type, if it
is unsigned.
From-SVN: r4752
({l,r}{shift,rotate}_double): COUNT arg is HOST_WIDE_INT, PREC is int.
(all_ones_mask): Remove __inline__.
(range_test): Make static; not used elsewhere.
From-SVN: r4750
(subst, case IF_THEN_ELSE): Make a shift when appropriate.
(simplify_shift_const): If we have an outer operation and made a shift, see if
it can be simplified.
From-SVN: r4748
(fold_truthop): Treat a BIT_AND_EXPR with a constant of one as if it were
surrounded with an NE_EXPR.
(fold): Don't move operation into conditional if it is BIT_{AND,OR}_EXPR with
the constant 1; change it to TRUTH_*_EXPR instead.
When moving things inside conditions, move comparisons as well as binary
operations.
Don't make a SAVE_EXPR when moving things inside conditionals unless the value
would really have been used twice.
From-SVN: r4746
(alloc_qty_for_scratch): Can allocate likely-spilled register classes
for SCRATCH.
(block_alloc): Likewise for regs in small register classes.
From-SVN: r4719
(output_encoded_offset): New function.
(output_epilogue): Minor changes to traceback table; call
new output_encoded_offset.
(romp_debugger_{auto,arg}_correction): New functions.
From-SVN: r4717
(fill_slots_from_thread): When replacing a use of a register with what
it was set to, don't do it when either the destination or source of
the copy is set in the insn.
From-SVN: r4716
Move most IGNORE processing to one place to avoid expanding things that don't
need to be expanded.
(expand_expr, case CONSTRUCTOR, case COND_EXPR): If IGNORE, don't expand
anything we don't have to.
(expand_expr, case CONVERT_EXPR): Don't deal with IGNORE here.
From-SVN: r4714
(local_alloc): Allocate and initialize them.
(block_alloc): Only allocate a SCRATCH if it can fit in the block we make.
Don't mark regs used in SCRATCH live here; instead, make entry in new tables.
From-SVN: r4713
(reload): Call it on each SCRATCH.
Free scratch list and block.
(spill_hard_reg): Reallocate any SCRATCH whose register we want to spill.
