Also drop the unnecessary python version variables.
If there are multiple python versions installed, the wrong one may be
picked. PYTHON_EXECUTABLE tries to avoid that problem, but the correct
way to spell this nowadays is Python3_EXECUTABLE.
Remove version.spec.inc from git
================================
We no longer track `version.spec.inc` in git. This is useful for
development. If we build a snapshot, the file is required but if we
build a `release` build (see below), then we don't include it.
Make improvements
=================
We distinguish between `snapshot-` and `release-` builds now in the
`Makefile`. These old targets are mapped to their new counterparts and a
deprecation warning is shown:
* `setup` -> `snapshot-setup`
* `local-rpm` -> `snapshot-rpm`
* `local-srpm` -> `snapshot-srpm`
* `local-prep` -> `snapshot-prep`
* `local-clean` -> `snapshot-clean`
We also have these new Make targets that run the build process with a
release tarball instead:
* `release-setup`
* `release-rpm`
* `release-srpm`
* `release-prep`
* `release-clean`
The targets `local-list-check` and `local-tmt-vm` have been commented
out because I think they were not needed. I just kept them for future
reference of research done in those areas.
All builds described by the `Makefile` are still local and no `mock` is
involved. I find this the easiest to debug.
Toggle default bcond state for snapshot_build
=============================================
We want to be able to build non-snapshot releases with this repo. That's
why be default the build condition `snapshot_build` is off. So
only when you explicitly enable `--with=snapshot_build` or define
`--define "_with_snapshot_build 1"` you'll be able to build a snapshot.
If however the build happens in Copr with a namespace that begins with
`fedora-llvm-team/llvm-snapshots-`, then the build condition is ON by
default and there's no need to enable it explicitly with `--with=snapshot_build`.
Things related to release update
================================
* Add llvm-project tarball and signature to sources
* Fix: error: source 1001 defined multiple times
* Fix: error: source 1006 defined multiple times
* Fix missing newline
* Conditionally apply 0001-Always-build-shared-libs-for-LLD.patch
* Only enable offload runtime in snapshot mode
Misc.
=====
* Add missing prep dependency
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.
The clang resource directory is always in lib/, while this was
creating the directories in lib64 (for 64-bit symbols).
This should fix the following error on ppc64le:
> error: Directory not found: /builddir/build/BUILDROOT/llvm-19.0.0~pre20240528.g1de1ee9cbabd64-1.fc39.ppc64le/usr/lib/clang/19/bin
