...was trying to build runtime libraries (compiler-rt) for ARM using “clang” which includes this code. A while ago, I saw the error message until geek4civic fixed it with “ERROR_QUIET”. I usually specify my sysroot and tool chain(linker) through CFLAGS. To fortify the logic, “${CMAKE_C_COMPILER} ${CMAKE_C_FLAGS} -Wl, --version” would be ideal than “${CMAKE_C_COMPILER} -Wl, --version” which works mostly for gnu compilers. Let me know, I can push a patch execute_process( - COMMAND ${CMAKE_C_COMPILER} -Wl,--version + COMMAND “${CMAKE_C_COMPILER} ${CMAKE_C_FLAGS}” -Wl,--version OUTPUT...

Hello LLVM, When building LLVM/Clang (debug build), linking takes too long. I notice that LTO is enabled now and guess that's to blame. Is there a CMAKE config option to disable LTO linking? I can't seem to find anything. Thanks, -steve

..., I have a cross compiler for ARM and I usually compile the code with Clang –sysroot=<path_to_sysroot> --gcc-toolchain=<path_to_toolchain> -target=<triple> file.c Where I pass “–sysroot=<path_to_sysroot> --gcc-toolchain=<path_to_toolchain> -target=<triple>” as CMAKE_C_FLAGS :) With out –gcc-toolchain, clang cannot find the linker and picks the system linker which is usually /usr/bin/ld on a linux system. --Sumanth G From: C Bergström [mailto:cbergstrom at pathscale.com] Sent: Tuesday, January 27, 2015 11:51 AM To: Sumanth Gundapaneni Cc: llvmdev at cs.uiuc....

Hi Nico, Hans, Takumi, I made it to the bottom of the issue. Turns out that CMAKE_C_FLAGS=-m64 CMAKE_CXX_FLAGS=-m64 CMAKE_EXE_LINKER_FLAGS=/machine:x64 is enough to do a 64-bit build correctly with a 32-bit clang-cl (i.e. one that targets 32-bit by default). Hooray! The missing piece that I had to track down is why I would see `deps = msvc` stuff spewing onto my terminal, rather than c...

There is no immediate support for this in the test-suite cmake buildsystem. There is something in the Makefile system indeed, but it lacks documentation and I'm not aware of any examples of how to use it. I would recommend to use `CMAKE_C_FLAGS=--save-temps=obj cmake ...` in the test-suite. The --save-temps=obj flag will make clang place a bitcode file next to each .o file. - Matthias > On Feb 26, 2018, at 9:42 AM, Gus Smith via llvm-dev <llvm-dev at lists.llvm.org> wrote: > > Hello all. > > I'm in need of a...

(kcc, george: sorry for the re-send, the first was from a non-list email address) My configuration for building the fuzzers in the LLVM tree doesn't seem to work any more (possibly as of moving libFuzzer to compiler-rt, but there have been a few other changes in the last week or so that may be related). I'm building with a fresh top-of-tree clang and setting -DLLVM_USE_SANITIZER=Address

Hello all. I'm in need of a benchmark that can be compiled to IR or bytecode. I found the test-suite project (https://llvm.org/docs/TestSuiteMakefileGuide.html) and thought a benchmark in that project might work. However, I'm having trouble figuring out how to actually compile any of the benchmarks to IR or bytecode. Using cmake and make I can compile them to binaries, but at no point do

Folks, As of this run: http://lab.llvm.org:8011/builders/clang-cmake-armv7-a15-full/builds/746 There are three classes of failures that need fixing before we get the bot green: 1. AddressSanitizer.BuiltinLongJmpTest Unit Test Two configurations fail: * Asan-arm-inline-Test * Asan-arm-with-calls-Test I wonder what's the best way to run it individually and reduce the error. I'm not
