...what inconvenient, because I want that my clang binary had builtins support for all the targets I enabled, and not only for those that have sanitizers support on the host machine. I disabled sanitizers in my build because they're quite difficult to compile in older OSs (so I invoke cmake with -DCOMPILER_RT_BUILD_SANITIZERS=OFF), but however, when invoking cmake, it's telling me that compiler-rt is targeting i386 and x86_64. No mention of the rest of LLVM targets I'm building. How can I get builtins for all architectures that have builtins support? Thanks!

Hello Peter and Lists, thanks a lot, that way it worked out!

...b, /usr/arm-linux-gnueabihf/lib, so no surprised there. Then I added the suggested -DCMAKE_ASM_FLAGS to the cmake for the standalone compiler-rt build while leaving out the --sysroot and --gcc-toolchain: cmake -G "Ninja" ../llvm/projects/compiler-rt/ -DCOMPILER_RT_BUILD_BUILTINS=ON -DCOMPILER_RT_BUILD_SANITIZERS=OFF -DCOMPILER_RT_BUILD_XRAY=OFF -DCOMPILER_RT_BUILD_LIBFUZZER=OFF -DCOMPILER_RT_BUILD_PROFILE=OFF -DCMAKE_C_COMPILER=/usr/local/myclang/bin/clang -DCMAKE_AR=/usr/local/myclang/bin/llvm-ar -DCMAKE_NM=/usr/local/myclang/bin/llvm-nm -DCMAKE_RANLIB=/usr/local/myclang/bin/llvm-ranlib -DCMAKE_TRY...

Hello, on the problems cross-building compiler-rt: Tried to follow https://llvm.org/docs/HowToCrossCompileBuiltinsOnArm.html which lead to this cmake: cmake -G "Ninja" ../llvm/projects/compiler-rt/ -DCOMPILER_RT_BUILD_BUILTINS=ON -DCOMPILER_RT_BUILD_SANITIZERS=OFF -DCOMPILER_RT_BUILD_XRAY=OFF -DCOMPILER_RT_BUILD_LIBFUZZER=OFF -DCOMPILER_RT_BUILD_PROFILE=OFF -DCMAKE_C_COMPILER=/usr/local/myclang/bin/clang -DCMAKE_AR=/usr/local/myclang/bin/llvm-ar -DCMAKE_NM=/usr/local/myclang/bin/llvm-nm -DCMAKE_RANLIB=/usr/local/myclang/bin/llvm-ranlib -DCMAKE_TRY...

I am currently trying to compile a pretty simple program to work on an experimental board. It contains an (FPGA-version of) an ARMv4 processor. So basically, I try this (on my Ubuntu 18.04.1 LTS): clang -v --target=arm-none-eabi -c barehello.c -o barehelloCLANG.o clang -v --target=arm-none-eabi -c io.c -o io.o clang -v --target=arm-none-eabi barehelloCLANG.o io.o -o helloCLANGstatic -static
