3832 PR tree-optimization/54985
3833 * tree-ssa-threadedge.c (cond_arg_set_in_bb): New function extracted
3834 from thread_across_edge.
3835 (thread_across_edge): Use it in all cases where we might thread

3842 2012-10-23 Richard Sandiford <rdsandiford@googlemail.com>
3844 * expmed.c (store_split_bit_field): Update the calls to
3845 extract_fixed_bit_field. In the big-endian case, always
3846 use the mode of OP0 to count the number of significant bits.
3847 (extract_bit_field_1): Remove unit, offset, bitpos and
3848 byte_offset from the outermost scope. Express conditions in terms
3849 of bitnum rather than offset, bitpos and byte_offset. Move the
3850 computation of MODE1 to the block that needs it. Use MODE unless
3851 the TMODE-based mode_for_size calculation succeeds. Split the
3852 plain move cases into two, one for memory accesses and one for
3853 register accesses. Generalize the memory case, freeing it from
3854 the old register-based endian checks. Move the INT_MODE calculation
3855 above the code that needs it. Use simplify_gen_subreg to handle
3856 multiword OP0s. If the field still spans several words, pass it
3857 directly to extract_split_bit_field. Assume after that point
3858 that both targets and register sources fit within a word.
3859 Replace x-prefixed variables with non-prefixed forms.
3860 Compute the bitpos for ext(z)v register operands directly in the
3861 chosen unit size, rather than going through an intermediate
3862 BITS_PER_WORD unit size. Simplify the containment check
3863 used when forcing OP0 into a register. Update the call to
3864 extract_fixed_bit_field.
3865 (extract_fixed_bit_field): Replace the bitpos and offset parameters
3866 with a single bitnum parameter, of the same form as extract_bit_field.
3867 Assume that OP0 contains the full field. Simplify the memory offset
3868 calculation and containment check for volatile bitfields. Make the
3869 offset explicit when volatile bitfields force a misaligned access.
3870 Remove WARNED and fix long lines. Assert that the processed OP0
3871 has an integral mode.
3872 (store_split_bit_field): Update the call to store_fixed_bit_field.
3874 2012-10-23 Richard Sandiford <rdsandiford@googlemail.com>
3876 * expmed.c (lowpart_bit_field_p): New function.
3877 (store_bit_field_1): Remove unit, offset, bitpos and byte_offset
3878 from the outermost scope. Express conditions in terms of bitnum
3879 rather than offset, bitpos and byte_offset. Split the plain move
3880 cases into two, one for memory accesses and one for register accesses.
3881 Allow simplify_gen_subreg to fail rather than calling validate_subreg.
3882 Move the handling of multiword OP0s after the code that coerces VALUE
3883 to an integer mode. Use simplify_gen_subreg for this case and assert
3884 that it succeeds. If the field still spans several words, pass it
3885 directly to store_split_bit_field. Assume after that point that
3886 both sources and register targets fit within a word. Replace
3887 x-prefixed variables with non-prefixed forms. Compute the bitpos
3888 for insv register operands directly in the chosen unit size, rather
3889 than going through an intermediate BITS_PER_WORD unit size.
3890 Update the call to store_fixed_bit_field.
3891 (store_fixed_bit_field): Replace the bitpos and offset parameters
3892 with a single bitnum parameter, of the same form as store_bit_field.
3893 Assume that OP0 contains the full field. Simplify the memory offset
3894 calculation. Assert that the processed OP0 has an integral mode.
3895 (store_split_bit_field): Update the call to store_fixed_bit_field.

24605 (rs6000_emit_savres_rtx): ..here. Add lr_offset param.
24606 (rs6000_emit_prologue): Generate frame_ptr_rtx as we need it.
24607 Set frame_reg_rtx to r11 whenever r11 is needed, and merge
24608 frame offset adjustment for out-of-line save with copy from sp.
24609 Simplify condition controlling whether cr is saved early or
24610 late. Use ptr_regno_for_savres to verify correct reg is set
24611 up for out-of-line saves. Pass the actual pointer reg used to
24612 rs6000_emit_savres_rtx so rtl matches insns in out-of-line
24613 function. Rearrange spe vars so code is similar to that
24614 elsewhere in this function. Don't update frame_off when spe
24615 save code will restore r11. Use emit_frame_save for spe and
24616 gpr saves. Consolidate darwin out-of-line gpr setup with that
24617 for other abis. Don't assume frame_offset is zero and frame
24618 reg is sp when setting up altivec reg saves, and calculate
24619 exact offset requirement.

24621 spe restore code. Consolidate darwin out-of-line gpr setup
