* Cleanup old avr-libstdcxx code and make it usable on other targetsQBos072024-12-231-9/+34
| | | | | | | | | | Should not cause major unwanted behavior changes - C++ is now selected by default in many configs. Signed-off-by: QBos07 <qubos@outlook.de> [cp: depend on CC_LANG_CXX instead of select] Signed-off-by: Chris Packham <judge.packham@gmail.com>
* allow plugins and LTO with static toolchainsChris Copeland2023-09-241-2/+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>
* Properly build multilib bare-metal RISC-VKirill K. Smirnov2023-07-141-0/+13
| | | | | | | | | To build multilib RISC-V toolchain one should use --with-multilib-generator option instead of --with-multilib-list. Add corresponding example configuration file. Signed-off-by: Kirill K. Smirnov <kirill.k.smirnov@gmail.com>
* gcc: Don't set --enable-default-pie by defaultKeith Packard2023-02-271-1/+1
| | | | | | | This changes how existing crosstool-ng setups work, causing many of the bare-metal ones to fail. Signed-off-by: Keith Packard <keithp@keithp.com>

* Enable support for building libgccjitMarc Poulhiès2022-12-181-0/+1
| | | | | | | | | | | | | | | | | | | | | 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>

| | | | | | | | | | | | PIE is not supported by PRU and AVR backends for GCC. This fixes LD errors when trying to link user programs with a crosstool-NG toolchain: /home/dinux/x-tools/avr/lib/gcc/avr/12.2.0/../../../../avr/bin/ld: -pie not supported collect2: error: ld returned 1 exit status Signed-off-by: Dimitar Dimitrov <dimitar@dinux.eu>

* Fixes for libstdcxx-verbose option tristateNorbert Lange2022-07-111-1/+0
| | | | | | | | Make it proper "tristate" by not specifying the option. The config GCC_4_8_or_later was removed with cc6b7fad46f5cb3d84, so dont use it.
* Allow libsanitizer on architectures that support itChris Packham2022-07-111-2/+9
| | | | | | | | | | | | libsanitizer is only supported on selected architectures. Add ARCH_SUPPORTS_LIBSANITIZER and have architectures select this option based on the list of supported configurations from GCC's libsanitizer/configure.tgt. Support for mips64 was added in GCC12 so this is an additional condition for the mips architecture. Fixes #1733 Signed-off-by: Chris Packham <judge.packham@gmail.com>
* kconfig: modify rules for multilibs configurationChen Tao2022-06-281-0/+1
| | | | | | | | | fix conflict options when compiling multilibs on ARM based architecture. "--with-arch", "--with-cpu", "--with-fpu", "--with-float", and "--with-mode" should not be configured with "--with-multilib-list=list" when configuring multilibs. Signed-off-by: Chen Tao <t.clydechen@gmail.com>
* Enable D language supportMarc Poulhiès2022-06-141-0/+1
| | | | | | | Enable D support as an experimental feature. GDC becomes a build dependency when enabled. Signed-off-by: Marc Poulhiès <dkm@kataplop.net>
* gcc: Disable zstd for canadian buildsChris Packham2022-05-311-2/+1
| | | | | | | | | | We don't currently bundle zstd so when performing a canadian build we need to tell GCC not to enable zstd support for lto otherwise it might decide to enable it based on the package being installed on the build machine. Fixes #1718 Signed-off-by: Chris Packham <judge.packham@gmail.com>
* gcc: Update fix for sh-unknown-elfChris Packham2022-05-311-1/+1
| | | | | | | | | Extend the fix from commit 6b465e15 ("Remove m1 from multilibs for GCC11 on SH arch.") to cover GCC 12 and future releases. Remove the patch that was added to solve the same problem. Signed-off-by: Chris Packham <judge.packham@gmail.com>
* gcc: add gcc libstdcxx-verbose optionNorbert Lange2022-02-231-0/+17

* Unify core passesAlexey Neyman2022-02-111-1/+1
| | | | | | | | | With libc_headers step before pass-1, there is no need to distinguish pass-1 and pass-2; they are configured identically (note that with the current configuration, core pass-2 is only used for win32 - hence, uses build_libgcc=yes and mode=static).

* Retire obsoleted milestonesAlexey Neyman2022-02-111-7/+2
| | | | | | | | | | | | ... and the code dependent on them, after the latest wave of obsolete package removals. This concludes the glorious history of the original uClibc (non-NG) with lots of kludges removed. There was a choice here, whether to call the resulting libc "uClibc" or "uClibc-ng". I opted in favor of giving uClibc-ng the recognition it deserves, although it had some ripple effect in the ct-ng code. Signed-off-by: Alexey Neyman <stilor@att.net>
* binutils: Remove obsolete versionsChris Packham2021-09-211-1/+0
| | | | | | | | | | | | | | | The following versions were marked obsolete in crosstool-ng-1.24.0, remove them. - binutils-linaro-2.23.2-2013.10-4 - binutils-linaro-2.24.0-2014.11-2 - binutils-linaro-2.25.0-2015.01-2 - binutils-2.23.2 - binutils-2.24 - binutils-2.25.1 Adjust the milestones now that the old versions have been removed.

* cc/gcc: Add options for zstd usageChris Packham2021-08-291-0/+19
| | | | | | | | | | | | GCC can support using zstd compression for LTO object files. By default GCC's configure will enable this if libzstd is installed on the machine building the toolchain. This may be undesirable if the toolchain is to be used on a different machine. Add an option to control zstd usage and set the default to the same as the current behaviour (i.e. auto). Fixes #1579 Signed-off-by: Chris Packham <judge.packham@gmail.com>
* gcc: Make CC_GCC_TM_CLONE_REGISTRY tristateChris Packham2021-06-201-1/+8
| | | | | | | | | | | | | | Explicitly passing --disable-tm-clone-registry causes gcc to create a crtbegin.o with a zero-sized .init_array/.fini_array. This in turn causes ld to complain. Make CC_GCC_TM_CLONE_REGISTRY a tristate so if it's not explicitly enabled we can let ./configure decide. Fixes #1531 Fixes: 1e21a302 ("gcc: Add CT_CC_GCC_TM_CLONE_REGISTRY config") Signed-off-by: Chris Packham <judge.packham@gmail.com>
* gcc: Add CT_CC_GCC_TM_CLONE_REGISTRY configStephanos Ioannidis2021-06-081-0/+7
| | | | | | | | | | | This commit adds a new gcc config `CT_CC_GCC_TM_CLONE_REGISTRY` that enables the GCC transactional memory clone registry feature for libgcc. Note that the gcc option to control this feature is only available in gcc 10 and above.

* Remove m1 from multilibs for GCC11 on SH arch.spaun20022021-05-051-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | GCC11 somehow has different set of multilibs on SH arch than what GCC10 had. In particular: $ gcc10 -print-multi-lib | sed -r -e 's/@/ -/g;' .; mb; -mb m2; -m2 m2e; -m2e m4; -m4 m4-single; -m4-single m4-single-only; -m4-single-only mb/m2; -mb -m2 mb/m2e; -mb -m2e mb/m4; -mb -m4 mb/m4-single; -mb -m4-single mb/m4-single-only; -mb -m4-single-only mb/m2a; -mb -m2a mb/m2a-single; -mb -m2a-single $ gcc11 -print-multi-lib | sed -r -e 's/@/ -/g;' .; mb; -mb m2; -m2 m2e; -m2e m4; -m4 m4-single; -m4-single m4-single-only; -m4-single-only mb/m1; -mb -m1 mb/m2; -mb -m2 mb/m2e; -mb -m2e mb/m4; -mb -m4 mb/m4-single; -mb -m4-single mb/m4-single-only; -mb -m4-single-only mb/m2a; -mb -m2a mb/m2a-single; -mb -m2a-single mb/m1 fails to build libgcc as libgcc uses opcodes that were not available in SH-1: libgcc/config/sh/lib1funcs.S uses 'bt/s' and 'dt' instructions that, according to https://antime.kapsi.fi/sega/files/h12p0.pdf become available in the SH-2 only. So I removed mb/m1 from the multilibs fog GCC11 and SH arch. Another option would be to try not to build libgcc for this combination of the gcc version and archichecture, but I thought this fix would be more robust.

| | | | | | | | | This has gone unnoticed for a while, it looks like all configurations have probably been using the default floats behaviour. Newer kconfig tells us the default value is not in the choice so lets fix this in preparation. Signed-off-by: Chris Packham <judge.packham@gmail.com>
* gcc: Add support for building libstdc++ with alternate libcKeith Packard2021-01-111-1/+1
