[PATCH] D113439: [RISCV] Add IR intrinsics for reading/write vxrm.

[Jessica Clarke via Phabricator via llvm-commits]

jrtc27 added a comment.

Even if you don't expose it in C the ABI still needs to specify what happens across call boundaries? I don't see what issues thread storage duration poses, as everything it implies is either a hard requirement (other threads don't clobber it) or for efficiency reasons (avoiding saving and restoring in any function that clobbers it)? It's a bit strange language to use though I'll admit given thread storage is a C language concept.
