This time with the missing files. Similar to PR/25526, fast-regalloc introduces spills at the end of basic blocks. When this occurs in between an ll and sc, the store can cause the atomic sequence to fail. This patch fixes the issue by introducing more pseudos to represent atomic operations and moving their lowering to after the expansion of postRA pseudos. This resolves PR/32020. Thanks to James Cowgill for reporting the issue! Reviewers: slthakur Differential Revision: https://reviews.llvm.org/D30257 llvm-svn: 296134
