Hello!
This patch will simplify macroization of AVX2 stuff. No functional changes.
2011-08-06 Uros Bizjak <ubiz...@gmail.com>
* config/i386/i386.md (ssemodesuffix): Remove V8SI mode.
* config/i386/sse.md (castmode): New mode attribute.
(avx_<castmode><avxsizesuffix>_<castmode>): Rename from
avx_<ssemodesuffix><avxsizesuffix>_<ssemodesuffix>.
Bootstrapped on x86_64-pc-linux-gnu, committed to mainline SVN.
Uros.
