-Subject: [PATCH] Removed clang-specific branch for x86 DCAS-based loads.
-
-The storage to load from is const-qualified and DCAS via compiler intrinsics
-require an unqualified pointer. Use asm implementation instead, which should be
-as efficient as intrinsics, if not better, in this case.
-
-Fixes https://github.com/boostorg/atomic/issues/15.
-
-Upstream-Status: Backport [https://github.com/boostorg/atomic/commit/6e14ca24dab50ad4c1fa8c27c7dd6f1cb791b534]
