Build fails because I have -mno-ssse3 in CFLAGS (since it is broken on x86(_32) Haswell).
Comment 1 Luke-Jr 2015-04-08 08:20:07 UTC 
Clarification: It is SSSE3 that is broken, not the -mno-ssse3 CFLAG :)
Comment 2 Sergei Trofimovich (RETIRED) gentoo-dev 2015-04-09 07:28:19 UTC 
Yeah, it's due to automagic support_aesni cabal flag enabled in ebuild. Fixing.

Thanks!

This doesn't really fix it: AES works fine on my CPU, just not SSSE3... Maybe add REQUIRED_USE="cpu_flags_x86_aes? ( cpu_flags_x86_ssse3 )"?

patch for ebuild

This uses both CPU_FLAGS_X86 flags and requires them both or neither.

Oh, I've mixed it with SSE3 :) Thanks for the fix!

I didn't use REQUIRED_USE as it's quite annoying for users to micromanage these binary things with 4 states of flags.

.ebuild will enable gcc's intrisics only when both flags are enabled
otherwise it will be silently disabled.
