[Qemu-devel] [PATCH for 1.3] target-i386: enable SSSE3 TCG support

[Aurelien Jarno]

SSSE3 support has been added to TCG more than 4 years ago in commit
4242b1bd8acc19aaaacffdaad4ac23213d72a72b. It has been disabled by
mistake in commit 551a2dec8fa55006a68393b9d6fb63577d2b3f1c.

SSE4.1 and SSE4.2 are wrongly disabled too, but some instructions from
SSE4.2 (I haven't investigated more yet) are wrongly emulated, which
causes some crashes now that GLIBC is using them through gnu indirect
functions.
