Hello!
When unaligned moves were split to unaligned store/loads, mode
calculation didn't get updated. Attached patch fixes this oversight.
2012-11-25 Uros Bizjak <ubiz...@gmail.com>
* config/i386/sse.md (<sse>_loadu<ssemodesuffix><avxsizesuffix>):
Do not depend on TARGET_SSE_TYPELESS_STORES.
(<sse2>_loaddqu<avxsizesuffix>): Ditto.
(<sse>_storeu<ssemodesuffix><avxsizesuffix>): Fix handling of
TARGET_SSE_TYPELESS_STORES.
(<sse2>_storedqu<avxsizesuffix>): Ditto.
Tested on x86_64-pc-linux-gnu {,-m32} and committed to mainline SVN.
Uros.
