(ix86_expand_special_args_builtin): Add get_pointer_alignment computed alignment and for non-temporal loads/stores also at least GET_MODE_ALIGNMENT as MEM_ALIGN. * config/i386/sse.md (<sse>_loadu<ssemodesuffix><avxsizesuffix><mask_name>, <sse>_storeu<ssemodesuffix><avxsizesuffix>, <sse2_avx_avx512f>_loaddqu<mode><mask_name>, <sse2_avx_avx512f>_storedqu<mode>, <sse3>_lddqu<avxsizesuffix>, sse_vmrcpv4sf2, sse_vmrsqrtv4sf2, sse2_cvtdq2pd, sse_movhlps, sse_movlhps, sse_storehps, sse_loadhps, sse_loadlps, *vec_interleave_highv2df, *vec_interleave_lowv2df, *vec_extractv2df_1_sse, sse2_movsd, sse4_1_<code>v8qiv8hi2, sse4_1_<code>v4qiv4si2, sse4_1_<code>v4hiv4si2, sse4_1_<code>v2qiv2di2, sse4_1_<code>v2hiv2di2, sse4_1_<code>v2siv2di2, sse4_2_pcmpestr, *sse4_2_pcmpestr_unaligned, sse4_2_pcmpestri, sse4_2_pcmpestrm, sse4_2_pcmpestr_cconly, sse4_2_pcmpistr, *sse4_2_pcmpistr_unaligned, sse4_2_pcmpistri, sse4_2_pcmpistrm, sse4_2_pcmpistr_cconly): Add ssememalign attribute. * config/i386/i386.md (ssememalign): New define_attr. * g++.dg/torture/pr59163.C: New test.
