Uros, does this make sense? Sure, but there are some other patterns missing athlon_decode attribute: *sse2_cvtpd2dq *sse2_cvttpd2dq sse2_cvtss2sd *sse2_cvtpd2ps sse2_cvtps2pd Can you please add missing athlon_decode attribute also for these? Patch is pre-approved for 4.7 and needs RM approval for 4.6.
