[PATCH] D61634: [clang/llvm] Allow efficient implementation of libc's memory functions in C/C++

[Guillaume Chatelet via Phabricator via cfe-commits]

gchatelet updated this revision to Diff 200998.
gchatelet added a comment.

- Use no-builtin instead of no-runtime-for.
- Use one attribute per runtime function to make merging easier.

The patch is still WIP and needs more work.
