https://gcc.gnu.org/bugzilla/show_bug.cgi?id=50481 --- Comment #12 from Andrew Pinski --- Also will add an internal function which will be used for vectorization.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=50481 --- Comment #11 from Andrew Pinski --- The builtins I am going to implement to be similar to clang: __builtin_bitreverse{8,16,32,64,g} The g one is not part of clang but will be used for _BitInt types.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=50481 --- Comment #4 from krux --- +1 The builtins already produce better code than a generic bitreverse implementation: https://godbolt.org/z/Um2Tit But using special hardware instructions automatically is even more important imho.
