libcxx: Default to compiler-rt when it is in PACKAGECONFIG

libcxx: Fix linking based upon chosen compiler runtime

2020-08-02T06:34:09+00:00

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

clang: stay closer to cmake.bbclass

2020-01-20T16:56:16+00:00

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

clang: Merge libunwind back into libcxx

2019-10-09T18:58:54+00:00

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

clang: Remove editing THUMB_TUNE_CCARGS

libcxx: Add packageconfig for compiler-rt use

2019-10-03T06:36:21+00:00

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
