* clang: Do not add lld linker for ppc32 when ld-is-lld is in distro featuresHEADmasterKhem Raj6 days1-1/+2
| | | | | | Causes binaries to segfault in qemu user mode Signed-off-by: Khem Raj <raj.khem@gmail.com>
* clang.bbclass,compiler-rt: Do not set -target for native clangKhem Raj2025-03-211-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | 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 <raj.khem@gmail.com>
* recipes: Update to match OE-Core virtual/cross-* changesRichard Purdie2025-01-211-1/+1
| | | | | | | 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 <richard.purdie@linuxfoundation.org>
* clang.bbclass: Use ld.lld as default for LD with ld-is-lldKhem Raj2024-10-101-0/+1
| | | | | | | | 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 <raj.khem@gmail.com>
* clang: Do not override default ld with ld.lldKhem Raj2024-10-101-11/+0
| | | | | | | | | | | 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 <raj.khem@gmail.com>
* clang.bbclass: remove mcpu option with qualifiers for the octeontx2 coreRuiqiang Hao2024-07-041-1/+1
| | | | | | | | | 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 <Ruiqiang.Hao@windriver.com>
* clang.bbclass: Do not lose TUNE_CCARGS_MARCH_OPTS when rewriting big.LITTLE mcpuKhem Raj2024-03-191-5/+13
| | | | | | | | | 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 <raj.khem@gmail.com>
* clang: Use +nocrypto with -mcpu for rpi3/rpi4Khem Raj2024-03-191-0/+4
| | | | | | This avoids qtwebengine crashes on rpi4/rpi3 Signed-off-by: Khem Raj <raj.khem@gmail.com>
* clang.bbclass: Stage along with gcc toolchainKhem Raj2023-11-121-1/+1
| | | | | | | | | 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 <raj.khem@gmail.com>

| | | | | | | | | | | allarch recipes do not really need compiler toolchains, otherwise they are not allarch Fixes issues like | ln: failed to create symbolic link 'TOPDIR/build/tmp/work/cortexa72-cortexa53-crypto-yoe-linux/ca-certificates/20211016-r0/recipe-sysroot-native/usr/bin/aarch64-yoe-linux/aarch64-yoe-linux-ld': No such file or directory Reported-by: Cliff Brake <cbrake@bec-systems.com> Signed-off-by: Khem Raj <raj.khem@gmail.com>

* clang.bbclass: Check for INHIBIT_DEFAULT_DEPS in creating ld->lld symlinkKhem Raj2023-06-091-1/+2
| | | | | | | | | | | When INHIBIT_DEFAULT_DEPS = "1" then the toolchain is not staged in Recipe specific native sysroot at all, therefore there is no point of creating the symlink Moreover it also fixes build of such recipes when ld-is-lld is set at distro level Signed-off-by: Khem Raj <raj.khem@gmail.com>
* clang.bbclass: create lld symbolic link in sysroot when ld-is-lld is setMing Liu2023-05-161-0/+10
| | | | | | | | | Create a symbolic link lld -> ld in recipe sysroot to choose the default linker lld when ld-is-lld is set in DISTRO_FEATURES. othereise, we can get linking issues when '-fuse-ld=lld' is in LDFLAGS but the actual ld is not lld. Signed-off-by: Ming Liu <liu.ming50@gmail.com>

| | | | | | | | | | file paths in debug info" Original issue has been fixed in clang 15+, -ffile-compilation-dir actually conflicts with creating separate -src packages since it confuses the packager about relative locations of the source files This reverts commit 224863150c9320b32f344792928af7fbda56d65d.
* clang.bbclass: Allow creating src-pkgsKhem Raj2022-10-071-1/+0

* clang.bbclass: Do not export llvm-config variablesKhem Raj2022-03-291-6/+4
| | | | | | | | | exporting them changes signatures of the tasks for all recipes includeing native ones, so when meta-clang is not used it ends up building all native recipes too. Defining these variables is good enought for clang to see them in do_compile shell for target recipes Signed-off-by: Khem Raj <raj.khem@gmail.com>
* clang.bbclass: Export YOCTO_ALTERNATE_LIBDIR and YOCTO_ALTERNATE_EXE_PATHKhem Raj2022-03-241-0/+9

* clang: set POPULATESYSROOTDEPS so that strip is presentRoss Burton2022-02-231-0/+3
| | | | | | | | | | | | do_populate_sysroot will execute the cross STRIP as part of the processing. In non-clang builds this is present via POPULATESYSROOTDEPS pulling in binutils, but in clang builds STRIP is set to llvm-strip which obviously isn't part of binutils.

* clang: Remove unintended dependency on gcc-runtimeEsben Haabendal2022-02-151-1/+3
| | | | | | | | | | | Commit a494bbb6ec44 ("clang: support android runtime") introduced an unrelated change causing builds with RUNTIME="llvm" and COMPILER_RT not set to get a dependency on virtual/${TARGET_PREFIX}compilerlibs.

| | | | | | | | | | | | We can not use nativesdk variants of libcxx and compiler-rt yet when compiling nativesdk-clang because, it will need this compiler to build them, so solve this catch-22, since we do not use the runtime built during compiler builds, use libgcc/libstdc++ to pass cmake tests during configure, this should be fine as it will be not needed for final builds where nativesdk-clang will be used, it can still default to llvm runtime on SDK host Signed-off-by: Khem Raj <raj.khem@gmail.com>
