* toolchain.eclass: don't depend on self if gnat-gplSam James2024-05-131-1/+1

| | | | | | | | | | | | The only change is that we've imported Gabi Falk's patch to fix a SyntaxWarning in its regexes.

* toolchain.eclass: iterate over older slots if test manifest doesn't existSam James2024-05-011-1/+11
| | | | | | | | | | | | | | Iterate over all known slots (at least those using the "new" SLOT value from --with-major-version-only since ~GCC 10 in Gentoo) if we couldn't find a test manifest for GCC_TESTS_COMPARISON_SLOT, rather than expecting pristine results. This makes life easier when installing a new slot (or newly enabling tests for one). It's *particularly* useful, I think, for arch testers who might want to establish a baseline once but not have to keep doing it across many chroots for each new slot.

| | | | | | | | | | | You *can* do LTO with libgccjit, apparently, and it even works if we don't break the compression used for LTO with it.

* toolchain.eclass: always generate a new test-suite baseline manifestGabi Falk2024-04-161-7/+9
| | | | | | | | | | | | | Previously, a new baseline was generated only in cases of test suite success or when GCC_TESTS_IGNORE_NO_BASELINE was enabled. After this change, if there is a test suite regression, users will have the option to copy the new baseline file to the cache if they choose to tolerate the regression. Additionally, the toolchain_pkg_preinst() function will update the baseline automatically if the package is built with the FEATURES=test-fail-continue setting.

* toolchain.eclass: do not ignore a baseline with GCC_TESTS_IGNORE_NO_BASELINEGabi Falk2024-04-161-1/+1
| | | | | | | | | | The GCC_TESTS_IGNORE_NO_BASELINE flag is intended to facilitate the initial generation of a baseline file, but it shouldn't affect the behavior if a baseline file already exists.

* toolchain.eclass: abort if hybrid CPU detected w/ -march=nativeSam James2024-03-241-2/+9
| | | | | | | | | | | | | | | | | | | | | | | | | Unfortunately, the previous approach can't work. --param doesn't fully wipe out the previous value added by -march=native, so we still get a failed comparison. Users hitting this should install app-misc/resolve-march-native, run resolve-march-native, and use that in their *FLAGS instead of -march=native - at least for sys-devel/gcc via package.env, if not in make.conf. Therefore, our only real option is to just abort when we detect a problematic situation and tell users what to do. The only other idea I had was to try taskset in src_compile which feels super brittle and not sure it'd even work at all. Thanks to Andrei for testing and debugging with us on IRC & the bug.

| | | | | | | | | | | | | | Hybrid/big.little/PE CPUs may report an inconsistent cache size across cores which can cause GCC's bootstrapping to fail its self-comparison. When CBUILD is amd64 or x86 and -march=native is in CFLAGS, iterate over all cores and record l1-cache-size. If any differ, use the first one we found.

| | | | | | | | | | | We want to have live ebuilds use e.g. 14.0.9999. not 14.0.1.9999 which is inconsistent and requires a rename/adjustment to package.accept_keywords files when going from stage3->stage4 (.0 -> .1).
