* toolchain.eclass: Don't inherit eutilsUlrich Müller2023-06-161-3/+0
| | | | | | | None of the ebuilds inheriting toolchain in EAPI 7 needs any of the remaining eutils features. Signed-off-by: Ulrich Müller <ulm@gentoo.org>

* toolchain.eclass: return to using -j1 for make installSam James2023-05-191-2/+12
| | | | | | | | | | | | | | | | Unfortunately, we have to use -j1 for make install. Upstream don't really test it and there's not much appetite for fixing bugs with it. Several reported bugs exist where the resulting image was wrong, rather than a simple compile/install failure: This reverts commit db0387530cf744068f480b68a192d4fc10a81286.

* toolchain.eclass: record EGIT_VERSION correctly in gcc --version for live ↵Sam James2023-04-271-0/+5
| | | | | | | | | | | | ebuilds Without this, gcc --version ends up only showing the commit resulting from applying our patches on top. With this fixed, gcc --version shows both the upstream commit & the commit hash after applying patches. Signed-off-by: Sam James <sam@gentoo.org>
* toolchain.eclass: don't enable openmp by default for >= 13Sam James2023-04-261-1/+8

* toolchain.eclass: wire up modula-2 frontend support for GCC 13; disable Rust ↵Sam James2023-04-181-1/+8
| | | | | | | | | | | | for 13 - Wire up modula-2 frontend support for GCC 13 as USE=modula2 - Drop Rust for GCC 13, upstream are going to make it fatal for configure for 13.1, but may revisit for 13.2 (not sure how likely that is, though, it depends on how much ends up backported). Rust will be available for GCC 14 though. We will revisit if changes occur, of course. Signed-off-by: Sam James <sam@gentoo.org>
* toolchain.eclass: pass improved checking for USE=debug for pre-releases tooSam James2023-04-131-8/+14

* toolchain.eclass: enhance USE=debug for more checkingSam James2023-04-131-1/+4
| | | | | | | | | | | We now do --enable-checking=yes,extra,rtl after discussion in #gcc for USE=debug. If rtl is too slow, we can do just yes,etra. We've actually found yet another bug with our general change for snapshots to start using checking, too: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=109506. Signed-off-by: Sam James <sam@gentoo.org>
* toolchain.eclass: use upstream default checking for pre/non-released compilersSam James2023-04-101-3/+6
| | | | | | | | | | | | | | Note that this only affects actually-non-released compilers like GCC 13 at this point in time and *not* snapshots from the stable branches. Upstream default to more checking (asserts/runtime integrity checks) when 'gcc/DEV-PHASE' contains 'experimental'. Copy that and defer to the configure.ac default when it does. The practical upshot of this is that we go from --enable-checking=release for GCC 13 to --enable-checking=yes,extra. Signed-off-by: Sam James <sam@gentoo.org>

* toolchain.eclass: Fix cross-compiling gcc for standalone prefixJames Le Cuirot2023-01-281-0/+15
| | | | | | | | | | | | | | | | Standalone prefix has always configured gcc with a sysroot, but the location of this sysroot is different at build time when cross-compiling. gcc has a separate configure option for that. prefix-guest systems do not have a sysroot applied, as they use the host's libc. Move this code from the prefix profile into the eclass so that it's less of a special case. We can avoid relying on the `BOOTSTRAP_RAP_STAGE2` variable by checking for the `prefix-guest` USE flag instead, as a prefix-guest profile is now used for RAP stage 2.

We only slot major versions now, so we should have our install paths reflect that for: 1. principle of least surprise; 2. we want LDPATH to remain valid between upgrades (bug #865835, bug #873505).

| | | | | | | | | | | | | | | The features/clang profile sets AS="clang -c". 1. We can't use llvm-as because it's essentially for internal use and isn't compatible anyway with cmdline args. 2. "clang -c" doesn't recognise --64 which configure tries to add. So, fake nothing to avoid configure trying to add that in.

* toolchain.eclass: BDEPEND on an Ada compilerSam James2022-09-121-0/+8

* toolchain.eclass: allow re-generation of info pages for snapshotsSam James2022-09-101-3/+23
| | | | | | | | | | | | | | | | | | Snapshots don't (yet?) contain pre-generated info pages (and man pages, but that's turned out not to be an issue, as they get regenerated and nobody notices). Given it's often easier and more sensible to keyword a snapshot from one of the stable branches upstream rather than cherry-picking patches, we need to make sure we don't regress with the documentation provided when we do that. Allow re-generation of info pages using texinfo for snapshots; we have a safeguard (eqawarn) for if they start appearing in snapshots and nobody noticed.

* Revert "toolchain.eclass: ensure thumb mode for armv6m"Marek Behún2022-08-231-2/+0
| | | | | | | | | | | | | | | | | | This reverts commit 903b71810e0b270a7d494e16e2d799fcd95ae50f. The commit caused default libgcc to be built in thumb mode for armv6m target, but it broke subsequent compilation of newlib via crossdev. The whole reason of this commit was to have the compiler generate correct code when libgcc was used in thumb mode, but now this is not needed anymore, because now we configure gcc with --with-multilib-list=aprofile,rmprofile for CTARGET=arm-* when used with multilib, which generates compiler that builds correct binaries for -march=armv6-m even if libgcc is used.

* toolchain.eclass: build multilibs for ARM's A, R and M architecture profilesMarek Behún2022-08-231-0/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For ARM targets, with USE=multilib and with CTARGET that does not imply any of --with-arch, --with-cpu, --with-mode or --with-float options to gcc's configuration (when arm_arch=arm), pass option --with-multilib-list=aprofile,rmprofile to gcc's configuration to make it build multilibs for A, R and M architecture profiles. This makes it possible to have one compiler capable of generating correct code (linking correct libgcc/CRT) for various ARM targets: from armv6 to armv7, for both soft float and half float, for various FPU types. Example of arm-none-eabi-gcc -print-libgcc-file-name output for various options: default: /usr/lib/gcc/arm-none-eabi/12.1.1/libgcc.a -mcpu=cortex-m0 /usr/lib/gcc/arm-none-eabi/12.1.1/thumb/v6-m/nofp/libgcc.a -march=armv7-m /usr/lib/gcc/arm-none-eabi/12.1.1/thumb/v7-m/nofp/libgcc.a -march=armv7-a /usr/lib/gcc/arm-none-eabi/12.1.1/thumb/v7-a/nofp/libgcc.a -march=armv7-a -mhard-float -mfpu=neon /usr/lib/gcc/arm-none-eabi/12.1.1/thumb/v7-a+simd/hard/libgcc.a -march=armv7-a -mhard-float -mfpu=vfp /usr/lib/gcc/arm-none-eabi/12.1.1/thumb/v7-a+fp/hard/libgcc.a Signed-off-by: Marek Behún <kabel@kernel.org> Signed-off-by: Sam James <sam@gentoo.org>
