As it was pointed out in https://github.com/llvm/llvm-project/pull/80724, we should not be checking `getLangOpts().Bool` when determining something related to logical operators, since it only indicates that bool keyword is present, not which semantic logical operators have. As a side effect a missing `-Wpointer-bool-conversion` in OpenCL C was restored since like C23, OpenCL C has bool keyword but logical operators still return int. >From 32b1b114cdf9c77af7a400b8f7705d50de2ef9de Mon Sep 17 00:00:00 2001 From: "Podchishchaeva, Mariya" <mariya.podchishcha...@intel.com> Date: Wed, 7 Feb 2024 03:07:47 -0800 Subject: [PATCH] [clang] Use CPlusPlus language option instead of Bool As it was pointed out in https://github.com/llvm/llvm-project/pull/80724, we should not be checking `getLangOpts().Bool` when determining something related to logical operators, since it only indicates that bool keyword is present, not which semantic logical operators have.
