[PATCH] D38966: CodeGen: Fix invalid bitcasts for atomic builtins

[Yaxun Liu via Phabricator via cfe-commits]

yaxunl created this revision.

Currently clang assumes the temporary variables emitted during
codegen of atomic builtins have address space 0, which
is not true for target triple amdgcn---amdgiz and causes invalid
bitcasts.

This patch fixes that.
