* toolchain.eclass: Move remaining gcc prefix tweaks from profileJames Le Cuirot2023-01-281-0/+13

* 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.

| | | | | | | | | This reverts commit 803ac64d367c4c865a2c30f1196dfec95dc7fee1. This was dropped upstream and no snapshots of GCC 13 in Gentoo use the variables from this commit anymore. Signed-off-by: Sam James <sam@gentoo.org>

| | | | | | | | | Adds TOOLCHAIN_SPHINX_BUILD. Upstream have converted their docs to Sphinx and it's needed for man, info, and HTML docs. There's no progress yet on including the files in dist tarballs though. Signed-off-by: Sam James <sam@gentoo.org>

| | | | | | | | | | | | | | | Flip over to major version install paths to reflect the change in slotting we made between 9 and 10. 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).

| | | | | | | | This reverts commit 7011340a0f13dcada6f3be48054957035bc6e01a. This ended up being insufficient. Signed-off-by: Sam James <sam@gentoo.org>
* toolchain.eclass: fix building Clang on pure LLVM profilesSam James2022-09-171-0/+11
| | | | | | | | | | | | | | | 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
| | | | | | | | Necessary but not sufficient. Needs a pkg_setup/pkg_pretend check for whether the active compiler supports Ada still, just like D needs this too (which isn't done either). Signed-off-by: Sam James <sam@gentoo.org>
* 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>

* toolchain.eclass: store previous test results & compare in src_testSam James2022-07-301-2/+42
| | | | | | | | | | | | | | | | | | | | This is what GCC developers do, so let's give it a try. Note that folks will have to (for now?) set GCC_TESTS_IGNORE_NO_BASELINE=1 for it to succeed if src_test failed for the first time & they don't have any test data saved for that slot. The test data is stored in ${EPREFIX}/var/cache/gcc/${SLOT}. GCC upstream's contrib/compare_tests script performs the comparison. We may want to investigate shipping baseline results / gathering them in a repo somewhere. We may also in future want to install this data as orphaned so that it's kept around and not lost when upgrading versions and to allow cross-slot comparison when an old one is depcleaned (although I guess doesn't matter so much if it's first time, but still).

| | | | | | | | | | To build GCC 12+ w/ D, we need a D compiler. For now, depend on GCC with D enabled. And give a hint to the PM that an older GCC is likely to do the job to break the cycle, as those don't need D to build their D support. Just in newer versions.

* toolchain.eclass: introduce TOOLCHAIN_PATCH_DEVSam James2022-06-021-3/+31
| | | | | | | | | | | | | | The PMS-legality of trying every entry in SRC_URI is questionable, so let's follow the model we use in some other places like the binutils + glibc ebuilds, and just add a variable for the developer hosting the patchset for an ebuild. We use an array in toolchain.eclass because it's easier. We also fall back to the old behaviour if TOOLCHAIN_PATCH_DEV is not set. Signed-off-by: Sam James <sam@gentoo.org>

* toolchain.eclass: ensure thumb mode for armv6mMarek Behún2022-05-301-0/+2
| | | | | | | | | | | | | | | | | | Currently the eclass ensures thumb mode compilation for libgcc for armv7m targets with [[ ${arm_arch} == armv7? ]] && arm_arch=${arm_arch/7/7-} ... [[ ${arm_arch} == *-m ]] && confgcc+=( --with-mode=thumb ) But libgcc should also be compiled in thumb mode for the armv6m target.
