[PATCH] D61052: [compiler-rt][builtins] Implement some fetch-and-x operations for Cortex-M

[Ayke via Phabricator via llvm-commits]

aykevl added a comment.

If someone could suggest a good way to test this, that would be great. At the moment it has been tested by compiling for armv6m, armv7m, and armv7em and confirming that the add operations appear to work.
