re PR target/56564 (movdqa on possibly-8-byte-aligned struct with -O3)
PR target/56564
* varasm.c (align_variable): Don't use DATA_ALIGNMENT or
CONSTANT_ALIGNMENT if !decl_binds_to_current_def_p (decl).
Use DATA_ABI_ALIGNMENT for that case instead if defined.
(get_variable_align): New function.
(get_variable_section, emit_bss, emit_common,
assemble_variable_contents, place_block_symbol): Use
get_variable_align instead of DECL_ALIGN.
(assemble_noswitch_variable): Add align argument, use it
instead of DECL_ALIGN.
(assemble_variable): Adjust caller. Use get_variable_align
instead of DECL_ALIGN.
* config/i386/i386.h (DATA_ALIGNMENT): Adjust x86_data_alignment
caller.
(DATA_ABI_ALIGNMENT): Define.
* config/i386/i386-protos.h (x86_data_alignment): Adjust prototype.
* config/i386/i386.c (x86_data_alignment): Add opt argument. If
opt is false, only return the psABI mandated alignment increase.
* config/c6x/c6x.h (DATA_ALIGNMENT): Renamed to...
(DATA_ABI_ALIGNMENT): ... this.
* config/mmix/mmix.h (DATA_ALIGNMENT): Renamed to...
(DATA_ABI_ALIGNMENT): ... this.
* config/mmix/mmix.c (mmix_data_alignment): Adjust function comment.
* config/s390/s390.h (DATA_ALIGNMENT): Renamed to...
(DATA_ABI_ALIGNMENT): ... this.
* doc/tm.texi.in (DATA_ABI_ALIGNMENT): Document.
* doc/tm.texi: Regenerated.
* gcc.target/i386/pr56564-1.c: New test.
* gcc.target/i386/pr56564-2.c: New test.
* gcc.target/i386/pr56564-3.c: New test.
* gcc.target/i386/pr56564-4.c: New test.
* gcc.target/i386/avx256-unaligned-load-4.c: Add -fno-common.
* gcc.target/i386/avx256-unaligned-store-1.c: Likewise.
* gcc.target/i386/avx256-unaligned-store-3.c: Likewise.
