Paolo Bonzini 958e1dd130 target/i386: Raise #GP on unaligned m128 accesses when required. ... Many instructions which load/store 128-bit values are supposed to raise #GP when the memory operand isn't 16-byte aligned. This includes: - Instructions explicitly requiring memory alignment (Exceptions Type 1 in the "AVX and SSE Instruction Exception Specification" section of the SDM) - Legacy SSE instructions that load/store 128-bit values (Exceptions Types 2 and 4). This change sets MO_ALIGN_16 on 128-bit memory accesses that require 16-byte alignment. It adds cpu_record_sigbus and cpu_do_unaligned_access hooks that simulate a #GP exception in qemu-user and qemu-system, respectively.
