* libcxx: Fix linking based upon chosen compiler runtimeKhem Raj2020-08-011-5/+6
| | | | | | | | | | | | | | | | | | | | | | libcxx can use either libgcc_s or llvm libunwind for unwinder functionality, the defaults are platform dependent, therefore with this patch we make intentional choice based on RUNTIME settings chosen, e.g. when using GNU runtime we use libgcc and also ensure that it add right compiler options to build as well, since libcxx build looks C runtime by calling $($CC --print-libgcc-file-name) to build libc++abi.so unless we use right -rtlib option it will result in linking wrong library Enable RTTI as well do not enable llvm unwinder unless we chose llvm runtime, even that might not work since libpthread from glibc explicitly dlopens libgcc_s.so to enable unwinding https://github.com/bminor/glibc/blob/5f72f9800b250410cad3abfeeb09469ef12b2438/sysdeps/nptl/unwind-forcedunwind.c#L53...L58 Fixes Issue #332 Signed-off-by: Khem Raj <raj.khem@gmail.com>

* clang: stay closer to cmake.bbclassDaniel McGregor2020-01-201-17/+3
| | | | | | | | | | | Allow more of the cmake variables coming from the OE environment through, otherwise the release C flags and CXX flags get reset to LLVM's default, which greatly extend build times. Also switch to using cmake.bbclass's do_compile and do_install commands. There's no need to call ninja directly anymore. Signed-off-by: Daniel McGregor <daniel.mcgregor@vecima.com>

* clang: Merge libunwind back into libcxxKhem Raj2019-10-091-2/+13
| | | | | | | | Do not export libunwind to other recipes besides libcxx itself, we use non-gnu libunwind on linux in general and its not a drop in replacement as of yet Signed-off-by: Khem Raj <raj.khem@gmail.com>

* libcxx: Add packageconfig for compiler-rt useKhem Raj2019-10-021-4/+4
| | | | | | | | | | This helps in disabling compiler-rt e.g. on risc-v if we need to enable exceptions then we need to use libgcc_s, since llvm-libunwind is not yet ported to risc-v For ppc, enable compiler-rt Signed-off-by: Khem Raj <raj.khem@gmail.com>

* libcxx: Pass OE LDFLAGS via CMAKE_SHARED_LINKER_FLAGSKhem Raj2019-10-011-6/+7
| | | | | | | | | | | setting these flags via CMake cmdline means that LDFLAGS that OE expects to insert via environment wont be respected anymore, therefore its better to pass it along during configure, so we get the desired flags into linker Fixes Issue #188 Signed-off-by: Khem Raj <raj.khem@gmail.com>

* libcxx: Facilitate building without llvm libunwindKhem Raj2019-09-091-10/+15
| | | | | | | | | | | | | | | | | | | | | | | when llvm unwind library is disabled, build was not picking up libgcc automatically since we still use, compiler-rt for C runtime, therefore introduce it via special CMAKE_SHARED_LINKER_FLAGS in packageconfig Bundle static unwind library into libcxx-abi library and bundle libcxx-abi.a into libc++.a this helps in just specifying lc++ and no other flags are needed. Also bundle static libunwind and cxx-abi but not into shared libc++, this would avoid adding them explicitly on linker cmdline in packages when doing static linking Use PREFERRED_PROVIDER_libunwind to determine if unwind packageconfig should be enabled or not Pass -fno-exceptions on arm, otherwise it links in unwinding routines which it expects to link from libgcc_s, we really don't need this when doing cmake checks so disable exceptions during cmake checks Signed-off-by: Khem Raj <raj.khem@gmail.com>
* libcxx: Add ^libunwind-locale-.* to PACKAGES_DYNAMICKhem Raj2019-09-091-0/+2

* libcxx: Add libunwind to PROVIDES not only RPROVIDES.Piotr Tworek2019-08-171-1/+1
| | | | | | | | | | | | Without this bitbake will still pull standard libunwind package when building recipes depending on libunwind. If such recipe also happens to pull libcxx the build will fail when assembling the sysroot because both libcxx and libunwind provide libunwind.so. This problem has been observed when building libstd-rs from meta-rust layer agains musl libc. Signed-off-by: Piotr Tworek <tworaz@tworaz.net>

* compiler-rt,libcxx: Add --stdlib=libc++ to compiler flagsKhem Raj2019-02-231-4/+5
| | | | | | | | | | - We do not need it with CXX - adding to compiler flag makes sure that libcxx headers are used even when C (clang) compiler is used - Eventually libcxx should provide virtual/${TARGET_PREFIX}compilerlibs add it in comments Signed-off-by: Khem Raj <raj.khem@gmail.com>
* compiler-rt: Disable standalone buildKhem Raj2019-02-091-0/+4
| | | | | | | | | | | standalone build starts to look for c++ headers which then are fed from libstc++ because libcxx is not built yet, instead let build use it from in-tree libcxx enable llvm-ar/llvm-ranlib/llvm-nm to provide ar/ranlib/nm respectively, this helps with lto enabled builds for libcxx Signed-off-by: Khem Raj <raj.khem@gmail.com>

| | | | | | | | | | | | | | 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>
* Disable generating libcxx.so as script for native and nativesdk caseKhem Raj2018-09-091-1/+3
