clang.bbclass: Rename to clang-legacy

2025-07-07T05:08:11+00:00

A similar bbclass is added to oe-core, so rename it as legacy class Signed-off-by: Khem Raj

clang: Do not add lld linker for ppc32 when ld-is-lld is in distro features

2025-05-07T01:09:21+00:00

Causes binaries to segfault in qemu user mode Signed-off-by: Khem Raj

clang.bbclass,compiler-rt: Do not set -target for native clang

2025-03-22T04:30:56+00:00

When building native recipes using clang as native compiler e.g. compiler-rt-native, setting -target can be out of sync with the underlying distro's understanding of gcc tuple e.g. aarch64-linux or aarch64-linux-gnu, which is used by distros to house the gcc runtime e.g. on ubuntu /usr/lib/gcc/aarch64-linux-gnu/11 /usr/lib/gcc/aarch64-linux-gnu/9 if we provide -target its not able to deduce it from the build host which is required for native packages try with recipe-sysroot-native/usr/bin/clang -xc /dev/null -rtlib=libgcc --unwindlib=libgcc -stdlib=libstdc++ -v or recipe-sysroot-native/usr/bin/clang -xc /dev/null -rtlib=libgcc --unwindlib=libgcc -stdlib=libstdc++ -target aarch64-linux -v to see the difference Signed-off-by: Khem Raj

recipes: Update to match OE-Core virtual/cross-* changes

2025-01-22T04:14:14+00:00

Update meta-clang to match OE-Core changes to use recipe specific virtual providers (without yet switching to the new switching mechanism). Signed-off-by: Richard Purdie

clang.bbclass: Use ld.lld as default for LD with ld-is-lld

2024-10-10T21:33:41+00:00

When ld-is-lld is in DISTRO_FEATURE, user wants to use lld as system linker, therefore honor the setting for bare linker as well, for compiler its being taken care by clang itself using -fuse-ld=lld Signed-off-by: Khem Raj

clang: Do not override default ld with ld.lld

2024-10-10T21:33:41+00:00

This creates a problem when swapping linkers, it does not work without cleaning the recipe first, in anycase if we want to use lld as default in clang then it should be done during clang compile Add packageconfig to let clang defualt Signed-off-by: Khem Raj

clang.bbclass: remove mcpu option with qualifiers for the octeontx2 core

2024-07-04T18:08:55+00:00

Currently, only the '-mcpu=octeontx2' option is removed, and any -mcpu parameters with qualifiers (such as +crc+crypto) are not removed, e.g., '-mcpu=octeontx2+crypto'. Remove these mcpu parameters with qualifiers by using '-mcpu=octeontx2${TUNE_CCARGS_MARCH_OPTS}'. Signed-off-by: Ruiqiang Hao

clang.bbclass: Do not lose TUNE_CCARGS_MARCH_OPTS when rewriting big.LITTLE mcpu

2024-03-19T16:52:16+00:00

Currently, clang options lose the qualifiers like +crc+crypto which are in TUNE_CCARGS_MARCH_OPTS when options like -mcpu=big.little are transformed to -mcpu=little as clang does not understand -mcpu=big.little while gcc does. Here we append TUNE_CCARGS_MARCH_OPTS after the rewrite Signed-off-by: Khem Raj

clang: Use +nocrypto with -mcpu for rpi3/rpi4

2024-03-19T16:52:16+00:00

This avoids qtwebengine crashes on rpi4/rpi3 Signed-off-by: Khem Raj

clang.bbclass: Stage along with gcc toolchain

2023-11-12T22:59:28+00:00

So far when using toolchain = clang would punt gcc from native-sysroot but its beneficial to keep both compilers since they can co-exist its not a big problem to have both in sysroot. This helps in debugging issues as well. Signed-off-by: Khem Raj
