--- Comment #10 from Uroš Bizjak <ubizjak at gmail dot com> --- Created attachment 36693 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=36693&action=edit Alternative patch Alternative patch that does a couple of things: - always defines BIGGEST_ALIGNMENT to 32 for TARGET_IAMCU - changes "misaligned_operand" to always use natural alignment of the operand - adds TARGET_IAMCU to generate unaligned vector load/store insns - fixes ix86_legitimate_combined_insn to consider ssememalign value The patch regresses sse-1.c (a very delicate test), where it generates slightly unoptimal, but still correct code. HJ, can you please test the patch for IAMCU, also with AVX target?
