| Test results columns: | |
| PASS XFAIL UNSUP FAIL SKIP UXPASS | |
| ^^^^ 4th column is the most important | |
| Detailed notes: | |
| 354 fails in LLVM: | |
| Many tests expect AT&T asm syntax, so LLVM tests were run with and without patch applied. | |
| built on Ubuntu 20.04: | |
| GCC 9 can't handle constexpr destructors, which are used somewhere in libc++ since 13. | |
| Latest versions of libc++ require glibc 2.24, whereas Xenial is based on 2.23. | |
| clang++ symlink: | |
| 2.7 and 2.8 create clang++ as an absolute symlinks. They have to be patched to make them relative. | |
| -lsupc++ required: | |
| Older libc++ tries to link against system libc++abi instead of just-built one. | |
| For this reason it waas configured to link against libsupc++. | |
| Clang 3.3 and 3.4 also doesn't have correct include paths to find libc++ in install prefix. | |
| linker script: | |
| Contents of `install-prefix/lib/libc++.so` is replaced with the following linker script: `INPUT(libc++.so.1 -lc++abi)` | |
| lit invoked using Python 3.9: | |
| On 12, `find_package(Python3)` is not supplied with minimal required version. Xenial defaults to 3.5, but lit relies on f-strings from 3.6. | |
| Solution is to take shell command that Ninja tries to run, adjust the path to 3.9, and run it manually. | |
| patched to enable clang for c++: | |
| In 2.6, Clang C++ frontend was considered of pre-production quality. By default it forwards sources to GCC. | |
| Patch disables the forwarding, because it would be a disservice to people who are interested in Clang 2.6 _today_. | |
| General notes: | |
| Directory layout: | |
| The following symbolic links have been used to replicate period-correct directory layout: | |
| (all) llvm/tools/clang -> clang | |
| (3.2 - 8) llvm/projects/compiler-rt -> compiler-rt | |
| (3.3) clang/runtime/libcxx -> libcxx (delete existing dummy directory) | |
| (3.4 - 8) llvm/projects/libcxx -> libcxx | |
| (3.6 - 8) llvm/projects/libcxxabi -> libcxxabi | |
| (3.7 - 8) llvm/projects/libunwind -> libunwind | |
| Test garbage in old versions: | |
| Tests from old version tend to leave *.pyc files after they are run. They can be cleaned out with the following command: `find llvm clang -name \*.pyc -delete` | |
