URL: https://github.com/llvm/llvm-project/commit/2bb72924c245e328e08dde546e5377273bd731f4 DIFF: https://github.com/llvm/llvm-project/commit/2bb72924c245e328e08dde546e5377273bd731f4.diff LOG: [clang] Remove source range from CXXOperatorCallExpr (#147028) This patch stops storing a source range in `CXXOperatorCallExpr` and keeps only the begin location. This change allows us to retain the optimization #141058 when switching to 64-bit source locations.
