[PATCH] D110684: [RISCV] Define _m intrinsics as builtins, instead of macros.

nikic added a comment.

I noticed this a few time in the past already, but this is the worst one yet:

Compile-time: https://llvm-compile-time-tracker.com/compare.php?from=6641d29b70993bce6dbd7e0e0f1040753d38842f&to=97f0c63783f52389bd8842df205379ceade7a89d&stat=instructions
Max-rss: https://llvm-compile-time-tracker.com/compare.php?from=6641d29b70993bce6dbd7e0e0f1040753d38842f&to=97f0c63783f52389bd8842df205379ceade7a89d&stat=max-rss
Plus a >1% increase in clang total binary size.

This happens every time a new slew of RISCV intrinsic permutations gets added, which seem to suffer from an extreme degree of redundancy. Is it possible to do something about this?
