[Bug target/60847] [4.9/4.10 Regression] x86 BMI intrinsics not recognized
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=60847 --- Comment #8 from Sanjay Patel spatel at rotateright dot com --- Thanks, Jakub. I see that the fix duplicates all of the intrinsics with a double-leading-underscore variant. Why do we need that? AFAIK, no other x86 intrinsics have this kind of duplication.

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=60847 --- Comment #9 from Jakub Jelinek jakub at gcc dot gnu.org --- (In reply to Sanjay Patel from comment #8) Thanks, Jakub. I see that the fix duplicates all of the intrinsics with a double-leading-underscore variant. Why do we need that? AFAIK, no other x86 intrinsics have this kind of duplication. That is because one kind of these intrinsics originates from AMD (support for AMD BMI is what went into GCC first) and the other from ICC which chose to provide different names. So, for backwards compatibility we need both sets.

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=60847 --- Comment #10 from Sanjay Patel spatel at rotateright dot com --- Ah - thank you for the explanation! I found the original checkin from AMD: http://gcc.gnu.org/ml/gcc-patches/2010-10/msg01356.html Strangely, I can't find any documentation for those double-underscores from AMD though.
