clang: Merge llvm/clang family recipes from meta-clang

2025-05-05T17:02:48+00:00

This can ensure that meta-clang does not carry them and can rely on core layer while mesa can use them too. Omit time stamps in openmp from generated files to improve reproducibility fix the issue that: | file /usr/include/llvm/Config/llvm-config.h conflicts between attempted installs of lib32-llvm-dev-20.1.2-r0.core2_32 and llvm-dev-20.1.2-r0.core2_64 (From OE-Core rev: d77e398095228b34851762858a76640e3c2cb0ab) Signed-off-by: Dmitry Baryshkov Signed-off-by: Khem Raj Signed-off-by: Richard Purdie

llvm: also install llvm-min-tblgen

2025-04-17T10:03:22+00:00

Some projects are picky and want to hanve llvm-min-tblgen in addition to a normal llvm-tblgen. Install the tool to the sysroot. (From OE-Core rev: b4acbadc16733c29024694ba0e5c0987dc7b459c) Signed-off-by: Dmitry Baryshkov Signed-off-by: Richard Purdie

llvm: import build fix from meta-clang

2025-04-17T10:03:22+00:00

Import a fix from meta-clang, which allows packages using LLVM to find tools from the native sysroot. (From OE-Core rev: 112b9d4c4c10d7ac0e2a8bc239d451b84b90c82c) Signed-off-by: Dmitry Baryshkov Signed-off-by: Richard Purdie

llvm: enable more targets to build

2025-04-11T10:44:22+00:00

Pull in the list of targets being enabled by meta-clang in order to make the libllvm from OE-Core runtime compatible with the one built by the clang recipe inside meta-clang. (From OE-Core rev: 672a21e16a2f4aadc588b367f0fd1ff1df7b5c67) Signed-off-by: Dmitry Baryshkov Signed-off-by: Richard Purdie

llvm: add SPIRV-LLVM-Translator support

2025-04-11T10:44:22+00:00

Mesa builds require SPIRV-LLVM-Translator in order to build CLC support. While it is possible to build it separately (like meta-clang does), it also requires a separate clang compiler (which OE-Core doesn't provide). Use an alternative path and build SPIRV-LLVM-Translator as a part of the LLVM build process, lifting the requirement for the separate clang. Once Clang is properly integrated into the OE-Core layer, this can be split to a separate package and dropped. In order to ease migration from meta-clang and to ease future split, PROVIDE the spirv-llvm-translator and make the llvm-spirv package RPROVIDE spirv-llvm-translator.

llvm: support building libclc

2025-04-11T10:44:22+00:00

Current Mesa requires libclc in order to build Intel Gallium (iris) or Vulkan drivers. In order to unblock Mesa updates, build libclc as a part of the LLVM build process. The libclc requires Clang for building, so enable Clang too via LLVM_PROJECTS. Remove clang from the DESTDIR, so that it is only used during the build process. Proper handling of Clang as a toolchain is a separate and much more complicated topic. Clang is enabled for all kinds of builds as it is a requirement for libclc to build. Cleaning of ${datadir} has been moved to happen at the end of do_install to be performed after do clang removal and made not to fail if ${datadir} is not empty, as libclc install files into that location. NVPTX and SPIRV targets are enabled since they are required for the libclc to link. LLVM_NATIVE_TOOL_DIR is used to pass a path to the native tools built via llvm-native instead of building them during the target and/or nativesdk build. The llvm-clc package is set to RPROVIDE libclc (and the recipe also PROVIDEs libclc) in order to be compatible with the meta-clang packages (and to be future-compatible with the split package after proper Clang support is introduced to OE-Core).

llvm: remove LLVM_LDFLAGS from llvm-config --ldflags output

2025-04-11T10:44:22+00:00

On native OE builds the LLVM_LDFLAGS gets a lot of extra flags which may depend on exact build dir and as such be inappropriate to binaries shared through sstate-cache. It is not possible to override this behaviour in llvm-config since crossscripts are not being used for native builds. Ignore LLVM_LDFLAGS for native builds.

llvm: also use llvm-config wrapper for nativesdk recipes

2025-04-11T10:44:22+00:00

The recipes targeting the SDK (e.g. nativesdk-mesa) should also use the llvm-config wrapper, otherwise they get get a lot of incorrect flags, the most offensive being the rpath, as it results in TMPDIR being a part of the resulting binary.

llvm: handle libdir in llvm-config

2025-04-11T10:44:22+00:00

The llvm-config wrapper also needs to override a --libdir switch, otherwise software (like mesa) end up using TMPDIR-based directory for Clang resource lookup (and also encoding TMPDIR into the target binary).

llvm: use OECMAKE_SOURCEPATH to specify cmake dir

2025-04-11T10:44:22+00:00

Instead of pushing an `llvm` sourcedir into S, specify it through the OECMAKE_SOURCEPATH so that all the patches are applied to the topdir and debug paths also use top path to map.
