Hello, I issued the following command to point the build to use clang and clang++, from a local llvm build directory included in PATH, instead of /usr/bin/{cc,c++}, cmake -DCMAKE_C_COMPILER=clang -DCMAKE_CXX_COMPILER=clang++ ../llvm_src The configuration failed with the error stating the compiler didn't recognize '-std=c++11' flag, whereas clang compiled a dummy c++ file with

Hallo all, I was trying to Build LLVM with the cmake option LLVM_ENABLE_MODULES just out of curiosity. I used the RELEASE_400/final tag. It didn't work as I almost expected. So I'm wondering if the modulemaps aren't maintained anymore? If they aren't maintained anymore, why aren't they removed and that cmake option also removed?

I had only a quick view on the blog-texts. It might be that a CLANG generated with LTO/PGO speeds up the build. Can you confirm this? Can you confirm binutils-gold speed up the build? Has LLVM an own linker? Can be used? Speedup the build? Yesterday night I loooked through available CMAKE/LLVM variables... ### GOLD # CMAKE_LINKER:FILEPATH=/usr/bin/ld #

That seems to work (see below). $ cd

Trying to run a self host "ninja check-clang" with ASan enabled I hit a /lot/ of errors like this (strangely I hit none of these in check-llvm, only in check-clang): Any ideas? ==10525==ERROR: AddressSanitizer failed to deallocate 0x10800 (67584) bytes at address 0x631000014800 ==10525==AddressSanitizer CHECK failed:
