URL: https://github.com/llvm/llvm-project/commit/0a2b5b03c4084ac1fefd0e62db2ba49f5ac24ab9 DIFF: https://github.com/llvm/llvm-project/commit/0a2b5b03c4084ac1fefd0e62db2ba49f5ac24ab9.diff LOG: [NVPTX][Fix] Ensure the return value of 'activemask' is unsigned Summary: The previous patch missed the `U` prefix, which caused the mask to be considered signed. This meant that conversions would incorrectly treat a full mask as a negative number and break things.
