# Pull the clang toolchain into the buildroot: the default mock buildroot
# only ships gcc, and this project's macros switch rpmbuild to clang.
Requires:       clang
Requires:       lld
# llvm-profdata, needed by specs whose CMake enables clang PGO (e.g. svt-av1
# with SVT_AV1_PGO=ON aborts with "llvm-profdata not found" without it).
Requires:       llvm

%description
Installs the macro override file at /etc/rpm/macros (rpm's site-default
override, loaded last), flipping this COPR project's builds to the clang
toolchain via redhat-rpm-config's native %toolchain machinery: clang +
ThinLTO (%_clang_lto) + x86-64-v3 [AVX2] baseline (%__cflags_arch_x86_64),
linking through lld (%_distro_extra_ldflags -fuse-ld=lld). Debug/debuginfo
subpackages are disabled for slim builds, and %%check is skipped (rebuild
repo). Requires clang+lld so the buildroot can actually run the switched
toolchain.

%changelog
* Tue Oct 13 2026 Garrus <128003623+lshyrilser1@users.noreply.github.com> - 1.0-10
- Override %dist to append ".clangopt" after the dist tag, so clang-opt rebuilds
  of identical-NVR Fedora packages sort strictly newer (3.fc45.clangopt >
  3.fc45) and dnf auto-selects/retains them. Ends the "dnf update never picks
  the optimized build; a manual reinstall --repo is required" behavior.
* Sun Oct 12 2026 Lutherus <128003623+lshyrilser1@users.noreply.github.com> - 1.0-9
- Require llvm: svt-av1's build enables clang PGO and aborts with
  "llvm-profdata not found" when the tool is absent from the buildroot.
* Sun Oct 12 2026 Lutherus <128003623+lshyrilser1@users.noreply.github.com> - 1.0-8
- Set the check-pre macro to a bare "exit 0". Appending it after the build-pre
  macro produced "cd <dir> exit 0" (build-pre has no trailing newline), which
  made the check script die with "cd: too many arguments".
* Sun Oct 12 2026 Lutherus <128003623+lshyrilser1@users.noreply.github.com> - 1.0-7
- Skip the check stage by making the check-pre macro exit 0; the without_check
  macro alone only feeds the conditional-build machinery and does not stop a
  literal check section (zlib-ng abicheck still ran).
- Undefine the mingw debug-package macro too, so suppressing the mingw debug
  install hook no longer leaves mingw file lists referencing a nonexistent
  debugfiles.list (libdeflate).
* Sun Oct 12 2026 Lutherus <128003623+lshyrilser1@users.noreply.github.com> - 1.0-6
- Keep Requires: clang, lld (a rebuild of 1.0-5 dropped them, so the buildroot
  lost clang and cmake failed with "CMAKE_C_COMPILER not set").
* Sun Oct 12 2026 Lutherus <128003623+lshyrilser1@users.noreply.github.com> - 1.0-5
- Disable %check globally (%_without_check) for rebuild-friendly builds
- Neutralize %__debug_install_post / %mingw_debug_install_post so specs that
  call debug hooks explicitly no longer leave unpackaged debug files
* Thu Sep 24 2026 garrus <garrus@localhost> - 1.0-4
- Ride Fedora's native clang toolchain machinery: %toolchain clang +
  %_clang_lto 1 (thin), %__cflags_arch_x86_64 -march=x86-64-v3 (composes
  into %{optflags}), %_distro_extra_ldflags -fuse-ld=lld (real cross-TU
  ThinLTO at link). Requires clang+lld: the base buildroot has neither, and
  hello canary (11032646) failed with "C compiler cannot create executables".
* Thu Sep 24 2026 garrus <garrus@localhost> - 1.0-3
- Install override at /etc/rpm/macros (site-default file, loaded last); the
  1.0-1/1.0-2 macros.d installs had zero effect on the build (gcc was still
  used), so rpm is not honoring macros.d content in the COPR buildroot.
- Add %_enable_debug_packages 0 alongside %_without_debug/%_without_debuginfo.
* Thu Sep 24 2026 garrus <garrus@localhost> - 1.0-2
- Install to /usr/lib/rpm/macros.d with z- prefix (loads after macros.redhat);
  the original /etc/rpm/macros.d path is not read by the COPR buildroot.
- Use %_without_debug/%_without_debuginfo (kernel-project-proven recipe).
* Thu Sep 24 2026 garrus <garrus@localhost> - 1.0-1
- Initial clang + ThinLTO + x86-64-v3 buildroot macros for clang-opt project.
