* clang: Move libclang into its own dedicated package.yoe/mutPiotr Tworek2019-07-261-1/+5
| | | | | | | | | This library has a few potential consimers (ex, qttools) which don't need whole clang install. Distributions like debian already package lbiclang separately as libclang1. This makes even more sense for embedded systems. Do the same for OE/Yocto. Signed-off-by: Piotr Tworek <tworaz@tworaz.net>
* clang: Add hf to target tuple if hard float calling convention is usedKhem Raj2019-04-091-1/+4
| | | | | | | | This ensures that right default target is used and one does not need to specify it manually using -target option or -mfloat-abi when using on target Signed-off-by: Khem Raj <raj.khem@gmail.com>
* clang: support old toolchainsAnuj Mittal2019-04-041-0/+1
| | | | | | | Allows building llvm/clang on Centos7 (gcc4.8) which still is one of the suported distros in YP. Signed-off-by: Anuj Mittal <anuj.mittal@intel.com>
* clang: Add compiler-rt and libcxx-dev to runtime depsKhem Raj2019-04-031-1/+2
| | | | | | | When installing clang to target its important to get these dependencies along with other llvm runtime, so clang can work out of box Signed-off-by: Khem Raj <raj.khem@gmail.com>
* clang: Use gold linker for nativersdkKhem Raj2019-02-111-12/+12
| | | | | | | | | | | | | | nativesdk packages are special in OE, where linker pads the dynamic section with additional bits so that can be patched to a relocatable location duting installing SDK, lld will need such a patch if it has to link the nativesdk apps, until then we use gold Add more fine grained packageconfigs for libpfm, ncurses, and libedit Enable clang as toolchain to build nativesdk version of clang with gold linker Signed-off-by: Khem Raj <raj.khem@gmail.com>
* clang: Fix nativesdk builds to use clang-nativeKhem Raj2019-02-111-8/+21
| | | | | | | | | | - User lld for linking nativesdk-clang - Enable LTO to build nativesdk-clang - Use -static-libgcc when using gold/lld for nativesdk clang build - Use llvm wrappers for ar ranlib and nm to help LTO - Package and create cross versions of lld Signed-off-by: Khem Raj <raj.khem@gmail.com>
* clang-nativesdk: Do not default to clang-runtimeKhem Raj2019-02-091-1/+1
| | | | | | | | | | | This make it use same runtime as the cross compiler default, which is more or less what is going to be case, if one wants to use clang runtime then it should be enabled across all clang variants (native/nativesdk/cross) Fixes Issue #66 Signed-off-by: Khem Raj <raj.khem@gmail.com>

* clang: Enable LTO and lld based on distro knobsKhem Raj2019-02-091-4/+5
| | | | | | | | | | | | | | | | | | | | | | | | Add to local.conf or distro config the following to enable lto flavors and lld linker DISTRO_FEATURES += "thin-lto" DISTRO_FEATURES += "full-lto" DISTRO_FEATURES += "lld" Add lto.bbclass To enable LTO is currently per recipe, or globally to enable globally add following to global config meta-data e.g. local.conf INHRIT += "lto" other-wise enable LTO per recipe using inherit lto to recipe via bbappend or in main recipe Signed-off-by: Khem Raj <raj.khem@gmail.com>

* clang: Switch to upcoming 8.0 release branchKhem Raj2019-01-191-4/+23
| | | | | | | | | | | | | | | Clang 8.0 is going to be released in Feb-March 2019 so here we switch to release/8.x branch a bit early so we can provide some feedback for release to be good on OE If one needs to use stable 7.0.1 release please use thud branch clang 8.0 does have RISC-V backend, enable it clang: Add building experimental targets e.g. riscv Signed-off-by: Khem Raj <raj.khem@gmail.com>
* clang,nativesdk-packagegroup-sdk-host: Recognise risc-vKhem Raj2018-12-271-0/+1
| | | | | | | This helps build SDKs for risc-v when meta-clang is in layer mix even though clang for risc-v may not fully work yet Signed-off-by: Khem Raj <raj.khem@gmail.com>
* nativesdk-clang: Rely on runtime build via libcxx and compiler-rt recipesKhem Raj2018-12-271-2/+0
| | | | | | | | This was trying to build runtime during build but we already have recipes for libcxx and compiler-rt to do that, unless we merge them into clang recipe, we need to keep using them to provide nativesdk clang runtime Signed-off-by: Khem Raj <raj.khem@gmail.com>
* recipes: Rework llvm/clang/compiler-rt/libcxx/lldb recipesKhem Raj2018-12-271-19/+4
| | | | | | | | | | | | | | This is an overhaul of clang/llvm project related recipes * switch to using a flat mono repo for all clang/llvm projects * Add llvm-project-source recipe which will prepare source tree in work-shared for all recipes much like kernel and gcc * build lld as part of clang recipes, its much easier and saves build time and hopefully nativesdk version will be built now for free * switch to official git repos at git://github.com/llvm-project * Adjust all recipes to use shared sources Signed-off-by: Khem Raj <raj.khem@gmail.com>
* recipes: Upgrade to clang 7.0.0 Release (rc2)Khem Raj2018-09-091-0/+2
| | | | | | | | | | | | | | | | | - Update compiler-rt/llvm/clang/lld licence checksums Triggerred due to copyright year update to 2018 Add libunwind and libcxxabi license to checksum list too - Switch to https protocol for fetching from github - Fix _finite functions on musl - Package new .so files built with clang - package libLLVM-${MAJOR_VER}.so as well since llvm-7 generates it without MINOR_VERSION Signed-off-by: Khem Raj <raj.khem@gmail.com>

| | | | | | | | Without this, we get a syntax error when we don't override LLVM_TARGETS_TO_BUILD_TARGET because LLVM_TARGETS_TO_BUILD_TARGET gets set as something like "X86X86" instead of "X86;X86". Signed-off-by: Martin Kelly <mkelly@xevo.com>
* clang: fix nativesdk buildMing Liu2017-08-231-1/+2
| | | | | | | | | | | | | | | | | | | | | I could not manage to build nativesdk-clang, I encountered errors as follows: (trimmed for purpose) | ../gcc/x86_64-pokysdk-linux/6.3.0/ld:: | cannot find crt1.o: No such file or directory | cannot find crtbegin.o: No such file or directory | cannot find -lgcc | cannot find -lgcc_s After some investigation, I found it's caused by the llvm native tools could not compile with crosssdk toolchains. (special linking flags are needed) So we introduce a cmake-native class with a task to generate a native toolchain file, it will be used to build llvm native tools by passed with CROSS_TOOLCHAIN_FLAGS_NATIVE.

* clang: Change LLVM_TARGETS_TO_BUILD to build everything by defaultKhem Raj2017-05-181-8/+9
| | | | | | | | | | | | | | | | | | | | As described in issue #33, LLVM_TARGETS_TO_BUILD should include build host as well as target arches and that fails since we build clang-native once for all due to its inherent cross compilable nature if one needs to limit the targets please set it in local.conf or via a bbappend in own layer e.g. LLVM_TARGETS_TO_BUILD = "ARM" if you only need 32bit arm or LLVM_TARGETS_TO_BUILD = "ARM;Aarch64" in case of both arm 32bit and 64bit fixes #33 Signed-off-by: Khem Raj <raj.khem@gmail.com>
* clang: update for cmake changes in oe-coreRoss Burton2017-05-051-6/+1
| | | | | | | | | | | cmake.bbclass in oe-core master (soon to be Pyro) doesn't set CMAKE_CROSSCOMPILING unconditionally, but only when it's actually cross-compiling. This means the clang-native build doesn't think it's cross-compiling, so the recipe can be simplified. Signed-off-by: Ross Burton <ross.burton@intel.com>
* clang: remove binutils from DEPENDS.Ismo Puustinen2017-03-231-1/+3
| | | | | | | Binutils is not needed during compile time. Add it instead to RRECOMMENDS_clang. Signed-off-by: Ismo Puustinen <ismo.puustinen@intel.com>
* clang: allow override for not building all targetsMartin Kelly2017-03-211-6/+18
| | | | | | | | | | | | | Allow the user to not build all clang target architectures (by default, all architectures are built). This speeds up build times and reduces image size. Note, however, that the set of architectures built must still be the same between the native and cross clang, because the native llvm-config reports --targets-built according to what "clang-native" supports. Thus when we have target libraries that are a subset of native libraries, the cross llvm-config will fail because it can't find some of the libraries that the native llvm-config finds. Signed-off-by: Martin Kelly <mkelly@xevo.com>
* clang: build libLLVM.soMartin Kelly2017-03-211-1/+8
| | | | | | | It's useful to have a shared library version of LLVM for programs that require it. Signed-off-by: Martin Kelly <mkelly@xevo.com>
* clang: fix the llvm-common wrapperMartin Kelly2017-03-211-6/+1
| | | | | | | | | | | | | | | | | | | | | | The llvm-common wrapper refers to the LLVM_WANT_RELEASE variable, which is not actually exported, so it fails. In addition, meta-clang does not support multiple side-by-side LLVM versions anyway, so the logic isn't really needed. After fixing these issues, I discovered that llvm-config doesn't cross-compile properly without more extensive wrapping. Specifically, the native llvm-config supplies --libdir, and other arguments relative to its current executable path, so it points into the native sysroot rather than the target sysroot. In addition, it supplies the native rather than the target compile CFLAGS, LDFLAGS, etc. Fix these issues by doing the following: - Alter the llvm-config to intercept certain flags, such as --cflags, while passing on other flags to the native llvm-config. - Patch llvm-config to be able to specify an alternate root location on which to base --libdir, etc. in order to optionally point into the target sysroot when needed.

* clang: Use TATGET_SYS instead of just TARGETKhem Raj2017-03-081-1/+1
| | | | | | | | | | | We need full triplet for it to use right linker/assembler for complete compile step, otherwise it invokes gcc to do linking and that confuses options e.g. pasing -Wa,--noexecstack gets passed to gcc during link, this is a gnu assembler option gcc: error: unrecognized command line option ‘--noexecstack’; did you mean ‘--no-backtrace’?
