Patch for RTL expand bug affecting aarch64 vector code.
gcc/
PR middle-end/79794
* expmed.c (extract_bit_field_1): Add alt_rtl argument. Before
maybe_expand_insn call, set ops[0].target. If still set after call,
set alt_rtl. Add extra arg to recursive calls.
(extract_bit_field): Add alt_rtl argument. Pass to
extract_bit_field.
* expmed.h (extract_bit_field): Fix prototype.
* expr.c (emit_group_load_1, copy_blkmode_from_reg)
(copy_blkmode_to_reg, read_complex_part, store_field): Pass extra NULL
to extract_bit_field_calls.
(expand_expr_real_1): Pass alt_rtl to expand_expr_real instead of 0.
Pass alt_rtl to extract_bit_field calls.
* calls.c (store_unaligned_arguments_into_psuedos)
load_register_parameters): Pass extra NULL to extract_bit_field calls.
* optabs.c (maybe_legitimize_operand): Clear op->target when call
gen_reg_rtx.
* optabs.h (struct expand_operand): Add target bitfield.
