* clang: Create symlinks with cross compile tuplesKhem Raj2020-09-251-0/+3
| | | | | | | | | This helps in running ptests e.g. perl which encodes the compiler during cross-compile and it is <cross-compile>-clang and not simply `clang` since these tests are configured and compiled on build host and run on target, its requied to have same names on target as well.

* clang: set the default pigz threadMingli Yu2020-08-121-0/+3
| | | | | | | | | | | | | | | | | | | | | | pigz, which stands for parallel implementation of gzip, is a fully functional replacement for gzip that exploits multiple processors and multiple cores to the hilt when compressing data. do_package uses pigz to compress data to speed up the time if there is pigz available on the build server. But for some big package such as clang, there comes below error during do_package. gzip: stdout: Cannot allocate memory tar: TOPDIR/sstate-cache/20/80/sstate:clang:cortexa57-wrs-linux:10.0.1:r0:cortexa57:3:20808f8a746b00ec9470a81057c8595d878cfe8c565cfbcbbaa3ea870528ee34_package.tgz.QF5dss8M: Wrote only 8192 of 10240 bytes tar: Child returned status 1 tar: Error is not recoverable: exiting now So set the default pigz thread for clang and the user also can customize the pigz thread such as PIGZ_pn-clang = "-p 3" for clang in local.conf to avoid eating so much memory.

* clang: Add packageconfig to select default unwinderKhem Raj2020-08-011-0/+1
| | | | | | | | | | a choice is needed to be made for selecting unwinder library defaults ( --unwindlib ), by default we choose libgcc unwinder when packageconfig is disabled and only use llvm unwinder when this option is enabled Fixes Issue #332 Signed-off-by: Khem Raj <raj.khem@gmail.com>
* 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: usrmerge workaroundOleksandr Ocheretnyi2020-07-021-0/+2
| | | | | | | | | | | | | | | |  * issue:     the openembedded-core build procedure relies on changed default dynamic loader path when the usrmerge distro feature turned on. As we can find the GCC which is used as default toolchain uses SYSTEMLIBS_DIR macro variable set to /usr/(lib|lib64) at build time and hardcodes the binaries with that default loader path.  * solution:     change the default dynamic loader location with --dyld-prefix clang option to conform the loader location (as GCC does) to openembedded-core build procedure.
