* eclass/toolchain.eclass: disable USE=vtv on gcc-10 and aboveSergei Trofimovich2021-02-221-1/+10
| | | | | | | | | | USE=vtv has a few problems: - it's build system has a few quirks: bug #767706, bug #582524 - it's developed in gcc for a while Bug: https://bugs.gentoo.org/582524 Bug: https://bugs.gentoo.org/767706 Signed-off-by: Sergei Trofimovich <slyfox@gentoo.org>
* eclass: [QA] Revert multiple meaningless doc changesMichał Górny2020-12-281-7/+1
| | | | | | | | | | | Revert multiple meaningless eclass documentation changes, notably adding a lot of placeholders and documenting implementation details. These changes were aimed at silencing (valid) documentation warnings without actually providing valuable documentation to the end users. While some of these changes were beneficial, it would take a lot of effort to review them all and the author is unwilling to fix his mistakes. Signed-off-by: Michał Górny <mgorny@gentoo.org>

* toolchain.eclass: add USE=custom-cflags for gcc-11Sergei Trofimovich2020-11-081-6/+13
| | | | | | | | | | | | | Sometimes it's useful to build gcc quickly with CFLAGS=-O0 as a smoke test for sanity. CFLAGS=-O3 should also generally work as a code generation stres test. But not in general case. Some options like -flto would probably not work as is. Let's allow users to experiment with gcc flags if they really want to.

* eutils.eclass: Deprecate use_if_iuse().Ulrich Müller2020-09-121-34/+43
| | | | | | | | The function is not called from any ebuilds in the gentoo repository. Inline it as "in_iuse foo && use foo" in other eclasses, or define it as a local function when it is called multiple times. Signed-off-by: Ulrich Müller <ulm@gentoo.org>

* toolchain.eclass: fix relocation of libgccjitSergei Trofimovich2020-08-241-0/+6
| | | | | | | | | | | | | | | | | Before the change libgccjit.so was installed to /usr/lib. Relocation code in toolchain.eclass:gcc_movelibs() only handles /usr/$(get_libdir) -> $LIBDIR location. As a result gcc did not relocate libraries to version-speciifc firectory: caused collisions and installed library into wrong LIBDIR. The change handles libgccjit special case by relocating it explicitly. Reported-by: Michał Górny Bug: https://bugs.gentoo.org/583010 Signed-off-by: Sergei Trofimovich <slyfox@gentoo.org>
* toolchain.eclass: always enable --with-long-double-128 for glibc targetsSergei Trofimovich2020-08-201-0/+8
| | | | | | | | | | | | | | | Unless overridden glibc enables 128-bit 'long double' for glibc 2.4 and above. But with crossdev change 7283a01 ("set --without-headers by default") we don't install any headers for stage1-gcc. As a result gcc pessimistically disables 128-bit 'long double'. The change enables --with-long-double-128 for glibc targets for stage1-gcc.

* toolchain.eclass: stop installing /usr/bin/c89 and /usr/bin/c99Sergei Trofimovich2020-08-191-15/+0
| | | | | | | | Ownership of /usr/bin/c89 and /usr/bin/c99 was switched to sys-devel/gcc-config-2.3.1. Closes: https://bugs.gentoo.org/728722 Signed-off-by: Sergei Trofimovich <slyfox@gentoo.org>
* toolchain.eclass: raise minimum gcc-config up to 2.3Sergei Trofimovich2020-08-071-1/+1
| | | | | | | | | | In #736040 gcc-config-1.9 was not able to handle gcc-10 paths. Let's raise lower bound to minimum stable version currently in ::gentoo. Reported-by: Dennis Nezic Bug: https://bugs.gentoo.org/736040 Signed-off-by: Sergei Trofimovich <slyfox@gentoo.org>

* toolchain.eclass: avoid libquadmath in stage1-gccSergei Trofimovich2020-07-301-0/+3
| | | | | | | | | | | | | | libquadmath relies on libc presence (sqrt symbols). When initial toolchain is bootstrapped libc is not available yet. The change disables libquadmath for bootstrap cases when libc is not installed yet. gcc-stage2 still uses platform defaults for libquadmath.

* toolchain.eclass: install libquadmath by defaultSergei Trofimovich2020-07-301-6/+0
| | | | | | | | | | libquadmath is a small support runtime library for _Float128 types. sci-libs/fftw happens to use it and expects it to be provided by gcc. Let's provide it unconditionally.

* toolchain.eclass: add USE=valgrind for annotations for valgrindSergei Trofimovich2020-07-061-0/+9

* toolchain.eclass: drop fix_libtool_files.shSergei Trofimovich2020-06-191-31/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | fixlafiles.awk can mangle two things in .la fils: 1. patch reference 'from .../libstdc++.la' to '-lstdc++' 2. change ${CHOST} when user switches CHOST and rebuilds the system [1.] is not relevant since gcc-4 in Gentoo where we started deleting libstdc++.la on gcc installation. Nothing should embed libstdc++.la paths anymore. [2.] is a rare one-off step that has a lot more caveats than just .la file patching. Generally .la files are tracked by package manager and should not be changed after they are installed on disk. 'fix_libtool_files.sh' breaks that invariant. On top of that portage's FEATURES=fixlafiles removes nested .la files references. Let's remove 'fix_libtool_files.sh' and 'fixlafiles.awk' completely. If really needed we can reintroduce it as a separate tool. Closes: https://bugs.gentoo.org/722554 Closes: https://bugs.gentoo.org/657330 Signed-off-by: Sergei Trofimovich <slyfox@gentoo.org>
* toolchain.eclass: drop unused --enable-altivecSergei Trofimovich2020-06-101-4/+7
| | | | | | | | | | | | | | --enable-altivec does not do anything since gcc-4: https://gcc.gnu.org/legacy-ml/gcc/2005-03/msg01091.html The change drops passing of --enable-altivec for all gcc versions and drops IUSE=altivec for gcc-10+. Once gcc-10 is stable everywhere we can drop IUSE=altivec for all gcc versions. Reported-by: Georgy Yakovlev Signed-off-by: Sergei Trofimovich <slyfox@gentoo.org>

| | | | | | | | | | | | | | In bug #701786 'strip-flags' removed all unsafe options first including -O3 and only then mangled -O? to -O2. This effectively made gcc to compalie wth -O0, generated huge slow profile and confused LTO. Let's default to safer -O3->-O2 transition.
