Richard Henderson 11e2bfef79 tcg/i386: Use MOVDQA for TCG_TYPE_V128 load/store ... This instruction raises #GP, aka SIGSEGV, if the effective address is not aligned to 16-bytes. We have assertions in tcg-op-gvec.c that the offset from ENV is aligned, for vector types <= V128. But the offset itself does not validate that the final pointer is aligned -- one must also remember to use the QEMU_ALIGNED() attribute on the vector member within ENV. PowerPC Altivec has vector load/store instructions that silently discard the low 4 bits of the address, making alignment mistakes difficult to discover. Aid that by making the most popular host visibly signal the error. Signed-off-by: Richard Henderson <richard.henderson@linaro.org>		2019-05-22 15:09:43 -04:00
