* gdb: Add gdb 15.1Chris Packham2024-07-241-0/+2
| | | | | | | | | | | | | https://sourceware.org/pipermail/gdb-announce/2024/000140.html The release notes state that "Building GDB and GDBserver now requires a C++17 compiler (for instance, GCC 9 or later)". Looks like we already satisfy this requirement with GDB_DEP_NO_STD_FUTURE. gdbserver now has a dependency on iconv.h, for uclibc configurations we need to make sure this is satisfied.

* Add mold linker buildArnaud Vrac2024-06-053-0/+20
| | | | | | | | | | | | | | | Allows building the #mold linker, which can then be used in the cross-toolchain by passing the -fuse-ld=mold to the gcc flags. It is much faster than ld or gold. This requires a C++20 compiler and cmake. Initially implemented by Arnaud, and HC added configure check for cmake. Outstanding task to validate compiler is C++20 compatible.

* Allow for Runtime-less build of GDC and GNATMarc Poulhiès2024-06-051-13/+15
| | | | | | | | | | | | Both D and GNAT have their own runtimes (resp. libphotos and libada). It is still possible to build the compiler proper without any runtime, and have an external runtime installed later. This is most commonly found in embedded systems. An example for D is: https://github.com/KitsunebiGames/tinyd-rt An example for Ada: https://github.com/Fabien-Chouteau/bare_runtime Signed-off-by: Marc Poulhiès <dkm@kataplop.net>
* musl: Mark not EXPERIMENTALChris Packham2024-05-242-4/+4
| | | | | | | | | | | | | Musl was marked experimental in commit 08d91d41 ("musl: config is broken for !EXPERIMENTAL"). Most of the reasoning for that change no longer applies and as it's been about 8 years it's time to let musl loose on the world. Drop the `depends on EXPERIMENTAL` and update the sample configs for aarch64 and x86_64. For powerpc64 the ABI needs to be elfv2. Enforce this via the powerpc config. Add a sample configuration for powerpc-unknown-linux-musl. Signed-off-by: Chris Packham <judge.packham@gmail.com>
* glibc: Disable -Werror for GCC14Chris Packham2024-05-181-1/+1
| | | | | | | Current glibc versions don't compile without warnings with GCC14. Disable -Werror for glibc when using GCC14. Signed-off-by: Chris Packham <judge.packham@gmail.com>
* Remove configure time check for rsyncChris Packham2023-12-181-3/+0
| | | | | | | Now that we're checking for rsync in Kconfig we can remove the check from ./configure. Signed-off-by: Chris Packham <judge.packham@gmail.com>
* config: Detect rsync presence at config timeChris Packham2023-12-183-2/+13
| | | | | | | | | | | | | | | | | | Linux kernel versions newer than 5.3 require rsync in order to export the UAPI headers. Commit f441a6bf ("linux: Add dependency on rsync for Linux >= 5.3") attempted to address this with a check that runs when crosstool-ng is built. That had the downside that if crosstool-ng was built and packaged on a machine that had rsync then run on a machine that didn't then the build would fail due to the missing rsync. Conversely if the first machine didn't have rsync installed when crosstool-ng was built then we would not offer newer kernel versions. We can address this by checking for rsync when the toolchain configuration is updated using some functionality in the newer Kconfig that we've updated to previously. Fixes #1940 Signed-off-by: Chris Packham <judge.packham@gmail.com>
* config/arch: Mark hppa/parisc as experimentalChris Packham2023-11-251-0/+2
| | | | | | | There are a number of things that don't currently work notably uClibc, C++ and GDB. Mark this architecture as experimental. Signed-off-by: Chris Packham <judge.packham@gmail.com>
* Add support for 32 and 64-bit PA-RISC linux build targets.John David Anglin2023-11-252-1/+12
| | | | | | | Note: The 64-bit target lacks a glibc port and doesn't build. Also, there is no uclibc support. Signed-off-by: John David Anglin <dave.anglin@bell.net>
* gdb: Use correct arguments for static linkingChris Packham2023-11-021-0/+5
| | | | | | | | | | | | As of version 13.x GDB uses libtool for linking instead of g++ these take different arguments for static linking. Commit 6146b5a6 ("use -all-static when building a static gdb") attempted to deal with this but had the effect of causing older GDB versions to fail to build statically. Add a new internal flag GDB_CC_LD_LIBTOOL and use this to decide whether to pass `-static` or `-all-static`. Fixes #2053 Signed-off-by: Chris Packham <judge.packham@gmail.com>
* m68k: Support MMUChris Packham2023-09-241-0/+1
| | | | | | | | | | Some m68k variants do have a MMU so the architecture can set ARCH_USE_MMU. That means we can have a m68k-unknown-linux-gnu configuration and that m68k-unknown-uclinux-uclibc needs to select LIBC_UCLIBC_NG since it's no longer the default. Fixes #2040 Signed-off-by: Chris Packham <judge.packham@gmail.com>
* allow plugins and LTO with static toolchainsChris Copeland2023-09-242-3/+0
| | | | | | | | | | | | This reverts commit 0841e2f820de7a4dca1ddc52b04bf834fff2806b from 2011, which disabled plugin support in binutils for static toolchains, citing build system problems. This problem seems to be resolved. This also reverts part of 45512b003d04b5a89c5c3bb6b674683d82b87f42 from 2017, which disabled LTO in gcc for static toolchains, citing problems on Arch Linux with loading the LTO plugin from a static binary.

* Add option to re-enable ˋlibstdc++ˋ on avr targets.Quentin Boswank2023-08-141-0/+9
| | | | | | | | | | | Due to the small flash space on AVR devices the library containing the standard types in C++ (ˋlibstdc++ˋ) does not get built normally when enabling the C++ language support. This option is an easy way to go back to the PC-way where ˋlibstdc++ˋ is built. Signed-off-by: Quentin Boswank <qubos@outlook.de>

* provide a workaround for a glibc and GNU make incompatibilityChris Packham2023-07-212-0/+12
| | | | | | | | | | | Versions of GNU make newer than 4.4 trigger a hang in versions of glibc older than 2.31. As distros update to the newer GNU make version we'll start seeing more and more reports of this hang. Fortunately we already carry GNU make as a comp tool so all we need to do is select the right version when needed. Fixes #1946, #1932, #1975 Signed-off-by: Chris Packham <judge.packham@gmail.com>
* Revert "Update requirements: autoconf==2.71 and automake>=1.16"Thomas Petazzoni2023-07-211-6/+6
| | | | | | | | | | | | | This reverts commit 658f5e574f4025655da318fb0b688a394b6ff43f, which was made without any justification, and prevents using crosstool-ng even in decently recent distributions like Ubuntu 20.04 (which has autoconf 2.69). We have tested that ./bootstrap && ./configure --enable-local works fine on Ubuntu 18.04, which uses autoconf 2.69 and automake 1.15, so the existing requirements were enough.

* | Enable support for building libgccjitMarc Poulhiès2022-12-182-0/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | libgccjit is still under development and, despite its name, may also be used for ahead-of-time compilation. Documentation can be found on the gcc website: https://gcc.gnu.org/onlinedocs/jit/internals/index.html https://gcc.gnu.org/wiki/JIT With this change it's possible to enable the building of the libgccjit. It's enabled as a language (with --enable-languages=jit) even if not a language frontend at all. The main changes are related to the requirement of having everything host side built as Position Independent Code (PIC) with --enable-host-shared. GCC has the needed logic for building its dependencies (mpc, gmp, mpfr, ...) correctly when built "in-tree", which is not the case with crosstool-ng (see https://gcc.gnu.org/git/?p=gcc.git;a=commit;h=05048fc29f0) Signed-off-by: Marc Poulhiès <dkm@kataplop.net>
