+Subject: [PATCH] [clangd] Fix detecting atomics in stand-alone builds |
43 |
+ |
44 |
+Include CheckAtomic CMake module from LLVM in order to detect support |
45 |
+for atomics when building stand-alone. Otherwise, |
46 |
+the HAVE_CXX_ATOMICS64_WITHOUT_LIB variable is undefined and clangd |
47 |
+wrongly attempts to link -latomic on systems not using the library. |
