This patch series introduces a test framework to run selftests for
target builds of Clang, LLVM, and LLD.
Summary of changes:
-Patch 1: Disable clang-tools-extra tests, as Clang's CMake cannot
detect the llvm-bcanalyzer target.
-Patch 2: Enabled the necessary CMake flags for clang, llvm & lld tests
-Patch 3: Selftest script for Clang, LLVM, and LLD including exclude list
-Patch 4: Fix rust build failure by replacing target llvm-config with native
Testing:
1. The test suite has been successfully validated on x86-64, arm64, riscv64
and arm32 for all Clang, LLD & LLVM components.
2. Clang and LLD tests passed successfully on x86. LLVM tests are skipped
on x86 since it's broken. A follow-up bug will be filed and addressed.
3. Clang, LLVM & LLD all together ~80K tests are there and we currently
~250 tests to exclude list which are failing (0.32%).
Impact on build time:
These builds were executed in a controlled environment without poky-sstate
enabled.
Default(without changes):
| Target | Run 1 | Run 2 | Run 3 | Average |
| --------- | ---------- | ---------- | ---------- | -------------- |
| llvm | 22m18.441s | 22m31.905s | 22m23.718s | 22m24.688s |
| clang | 30m09.774s | 30m22.680s | 30m15.312s | 30m15.922s |
| lld | 1m26.994s | 1m30.415s | 1m29.006s | 1m28.805s |
With the testsuite changes applied:
| Target | Run 1 | Run 2 | Run 3 | Average |
| --------- | ---------- | ---------- | ---------- | -------------- |
| llvm | 23m32.104s | 23m45.887s | 23m38.157s | 23m38.716s |
| clang | 30m31.402s | 30m46.198s | 30m39.445s | 30m39.015s |
| lld | 1m29.845s | 1m34.212s | 1m31.925s | 1m31.994s |
Comparison:
| Target | Default Avg | With Changes Avg | **Diff** |
| --------- | ----------- | ---------------- | ---------------- |
| llvm | 22m24.688s | 23m38.716s | +1m14.028s |
| clang | 30m15.922s | 30m39.015s | +0m23.093s |
| lld | 1m28.805s | 1m31.994s | +0m3.189s |
Impact on tmpdir size:
| Metric | Size |
| ------------------------------------ | ----- |
| Default target `tmpdir` size | 74 GB |
| Target `tmpdir` size (after changes) | 79 GB |
| Difference | +5 GB |
