similar to: [LLVMdev] CMake configuration: Detecting zlib.h header in windows.

I've been working on getting the LLVM OpenMP library to build smoothly alongside llvm/clang using CMake, but one problem I'm having is determining exactly which CMake option designates the architecture the compiler will compile. I see LLVM_TARGET_ARCH, LLVM_TARGETS_TO_BUILD, LLVM_DEFAULT_TARGET_TRIPLE, etc. I thought I should just ask which one designates the architecture the compiler

I'm trying to build LLVM, Clang, LLD, compiler-rt, libc++, libc++abi and libunwind with musl-based toolchain. The configuration is the following: LIBCXX_HAS_MUSL_LIBC=ON LIBCXX_HAS_GCC_S_LIB=OFF CLANG_DEFAULT_CXX_STDLIB=libc++ CLANG_DEFAULT_LINKER=lld CLANG_DEFAULT_RTLIB=compiler-rt LLVM_DEFAULT_TARGET_TRIPLE=x86_64-pc-linux-musl LLVM_TARGET_ARCH=x86_64

Hi, the first question is addressed both to llvm-dev and gentoo-dev. The second one is Gentoo specific. Is there any possibility to build LLVM both as static and shared libraries? What I see currently is that our ebuild makes LLVM to build shared libs unconditionally. Is there a possibility (if it is impossible to build both lib types) to at least give to user control on what kind of libs he

[Sorry about the crosspost. Since this is a clang build question but the build is invoked from the top-level LLVM directory I'm not sure where the question should go.] I've got a clang build against libstdc++ on Linux but I would really like one built against libc++/libc++abi. In other words I'd like to rebuild clang/llvm with clang using libc++ and libc++abi on Linux. I looked at

This is currently a rough area in our build system, but there are two CMake options you probably need to set. (1) -DLLVM_BUILD_EXTERNAL_COMPILER_RT=On —> This option causes the build to use the just-built clang when building compiler-rt (2) -DCOMPILER_RT_DEFAULT_TARGET_ARCH=??? —> This is where you specify which architecture you want to build the compiler-rt archives and libraries for

Just to follow-up, I'm now encountering this as well. I'm doing this on Linux. It seems that when linking with the most-recently built clang, the unit tests are taking a while to complete. It's notably not using more than 1 thread, and if using `lld` I would have expected the linker to still be running in parallel. I'm doing this on a debug build, so that might help narrow it

These errors seem pretty pervasive for me on a clean build. It appears that it arises because when tablegen'd headers are included in a .h file, every place where that .h file is used needs a dependency on the corresponding IncGen targets. This seems broken in the short term and unmaintainable in the long term. There really needs to be a way of automatically generating the right

Hi, If you create an Xcode project with cmake -G Xcode ~/llvm and do a build, you end up with 68 warnings like this: -mdynamic-no-pic overrides -fpic or -fPIC This can be easily avoided doing: cmake -G Xcode -ULLVM_ENABLE_PIC ~/llvm But I think it would be nicer if it built warning-free with the simpler form. What do you think? Ray PS: CMake generated make style builds on

As part of trying to fix PR30610 (ThinLTO with module inline asm), I wanted to add an assert that we have a Target and an MCAsmParser when we have non-null module inline asm in IRObjectFile::CollectAsmUndefinedRefs. Otherwise it silently fails to parse the module inline asm, which I initially found when trying to add an 'opt' based test for my fix (because 'opt' wasn't

I have been working for extending test coverage for years. Nowadays, I have several cross-testing (target != host). See http://bb.pgr.jp/console Each of them (test-*-linux) is doing; - Assume a preceding builder passes with warming ccache. - All compilation units will hit ccache whenever the tree is built before lit. - Almost all compilation units will hit ccache except for Host.cpp when

Hello, I was looking at sys::getDefaultTargetTriple() (file: lib/Support/Unix/Host.inc ) and there is something unclear to me. std::string sys::getDefaultTargetTriple() { StringRef TargetTripleString(LLVM_DEFAULT_TARGET_TRIPLE); std::pair<StringRef, StringRef> ArchSplit = TargetTripleString.split('-'); // Normalize the arch, since the target triple may not actually

I want to build LLVM-based toolchain with Musl, I have LLVM sources with clang and lld (under `tools` directory) and libunwind, compiler-rt, libcxx and libcxxabi (under `projects` directory). All are the latest versions cloned from GitHub mirror, branch `master`. I'm trying to configure with the following options: CLANG_DEFAULT_CXX_STDLIB = libc++ CLANG_DEFAULT_RTLIB = compiler-rt

Hi - attached is a patch to enable building DragonEgg (x86_64) for LLVM3.3 and LLVM3.4. That is, add these changes to the 3.3 release, and it becomes possible to build DragonEgg against a llvm3.4 compiler.

Is there a simple way to override the target triple used in when running the generic codegen tests?
