Indded since llvm 15 this option check for C++17 [1] The last gcc 7.x version (7.5) has been released in 2019. Fixing llvm/clang issues for old compiler maybe it's not worth it. - Remove LLVM_TEMPORARILY_ALLOW_OLD_TOOLCHAIN since gcc >= 7 is mendatory. When updating LLVM, we also need to update the version of SPIRV_LLVM_TRANSLATOR because its CMakeLists.txt verifies the LLVM base version [2]. The patch package/llvm/0002-Add-missing-cstdint-header-to-Signals.h.patch has been included in tag llvmorg-15.0.0 of llvm-project. [1]4c72deb613
