This should make it easier to analyze which parts of the build
are slow. The new package is only available in snapshot builds,
we don't want to ship it in production.
This ports the change from https://src.fedoraproject.org/rpms/compiler-rt/pull-request/67
to big-merge, which is a bit more complicated here due to the
explicit file lists.
By default compiler_rt_triple is the same as llvm_triple. For x86
it is i386-redhat-linux-gnu instead, with a symlink to the
llvm_triple i686-redhat-linux-gnu.
And then the file list also needs to ship that symlink.
Fix these errors on s390x by excluding the files on that arch:
File not found: /builddir/build/BUILDROOT/llvm-19.0.0~pre20240526.gc87a7b3bdb6737-1.fc41.s390x/usr/lib/clang/19/lib/s390x-redhat-linux-gnu/clang_rt.crtbegin.o
File not found: /builddir/build/BUILDROOT/llvm-19.0.0~pre20240526.gc87a7b3bdb6737-1.fc41.s390x/usr/lib/clang/19/lib/s390x-redhat-linux-gnu/clang_rt.crtend.o
File not found: /builddir/build/BUILDROOT/llvm-19.0.0~pre20240526.gc87a7b3bdb6737-1.fc41.s390x/usr/lib/clang/19/lib/s390x-redhat-linux-gnu/liborc_rt.a
Fix this error on i686 by explicitly creating the directory.
This matches what the implementation did pre-big-merge. I think
we do want to keep this directory structure consistent across all
arches.
Directory not found: /builddir/build/BUILDROOT/llvm-19.0.0~pre20240526.gc87a7b3bdb6737-1.fc41.i386/usr/lib/clang/19/bin
The list of supported sanitizers differs per target, and depending
on that some of these files may or may not be present. Use a
wildcard rather than explicitly listing this out.
https://github.com/llvm/llvm-project/pull/92456 added a new
libclang_rt.ctx_profile.a library.
Given that these all have a fixed prefix, I think it's fine to
use a wildcard for them instead of explicitly listing them.
Before I've used `%ifnarch` in the `<FILE>` included with `%files -f <FILE>`.
This produced this error:
```
RPM build errors:
File must begin with "/": %ifnarch
File must begin with "/": i386
File must begin with "/": i486
File must begin with "/": i586
File must begin with "/": i686
File must begin with "/": pentium3
File must begin with "/": pentium4
File must begin with "/": athlon
File must begin with "/": geode
File must begin with "/": %endif
```
We can optimize this at any point in time later.
We had too many `*.so` libraries added to the `clang-devel` package.
Before we've added these implicitly by accident:
```
/usr/lib64/libLLVM.so.19.0pre20240509.g943617d12ccbd3
/usr/lib64/libLTO.so.19.0pre20240509.g943617d12ccbd3

```
And now we're adding just these because these are the ones that used to
exist within the clang-devel package when it was still being built in
standalone mode:
```
/usr/lib64/libclang-cpp.so
/usr/lib64/libclang.so
```
* %check: export LD_LIBRARY_PATH because runtimes use external cmake projects that wouldn't find libclang++.so
* %check: use LLVM's LIT_XFAIL to mark tests that are expected to fail and don't just delete them
* clang: bring over *.patch files
* clang: remove build requires tags from clang package that are already defined by main llvm package
* clang: remove duplicates found in llvm globals and use %{pkg_datadir} instead of %{install_datadir}
* clang: rename and use pkg_name -> pkg_name_clang
* clang: use %{pkg_name_clang} instead of %{name}
* compiler-rt and libomp: wrap in %if %{without compat_build}
* libomp: also build libomp for s390x (See https://github.com/llvm/llvm-project/pull/66081)
* libomp: exclude libomp-devel on s390x just like libomp itself
* libomp: introduce pkg_name_libomp and cleanup the globals
* libomp: remove gdb-plugin (NEED TO CONFIRM IF THIS IS REALLY TRUE)
* libomp: filter out flaky libomp test: ompt/teams/distribute_dispatch.c
* llvm: add BuildRequires: graphviz to llvm-doc
* llvm: use %{pkg_name_llvm} instead of %{name}
* make: added temporary Makefile so I can more easily run srpm or rpm builds locally
* make: Added local-tmt-vm target (not really useful yet)
* rpm: for non-RHEL add prefix like "Jan 05 16:17:06" to every log line This should help in finding out how long things take to build/install/...
* rpm: fully specify %files for top-level packages
* rpm: make all packages fully qualified
* rpm: obsolete llvm-snapshot-builder
* rpm: remove BuildRequires: python3-lit because we have it in-tree
* rpm: remove BuildRequires: tags for clang and llvm specifics as we're building in-tree
* rpm: rename %llvm_srcdir -> %srcdir_llvm
* rpm: rename %pkg_name -> %pkg_name_llvm
* rpm: use full qualified name in %description
* rpm: use region comments in spec file to group by package. This allows editors to fold text to get a better overview
* rpmlint: update rc file to reflect clang and compiler-rt (libomp has no rpmlint rc file)
* use python-lit from within tree
