* build: add support for using prebuilt LLVM toolchainFelix Fietkau2021-11-041-0/+14
| | | | | | | | When the prebuilt llvm toolchain is unpacked into the source dir, it is automatically picked up and used by the build system, and eBPF based packages can be selected Signed-off-by: Felix Fietkau <nbd@nbd.name>
* llvm-bpf: support creating a tarball in binFelix Fietkau2021-11-041-0/+2
| | | | | | | | This can be used for adding the toolchain to an existing tree without having to build it from scratch. Enable building the toolchain + tarball by default on buildbot Signed-off-by: Felix Fietkau <nbd@nbd.name>
* build: fix bpf toolchain dependency for qosifyFelix Fietkau2021-11-011-0/+13
| | | | | | Add hidden symbols to fix defaults with CONFIG_DEVEL unset Signed-off-by: Felix Fietkau <nbd@nbd.name>
* config: add choice for selecting the LLVM toolchain typeFelix Fietkau2021-11-011-6/+24
| | | | | | This is global for all BPF based packages Signed-off-by: Felix Fietkau <nbd@nbd.name>
* tools/llvm-bpf: add llvm+clang build suitable for compiling code to eBPFFelix Fietkau2021-10-201-0/+7
| | | | | | Preparation for building packages that ship eBPF code Signed-off-by: Felix Fietkau <nbd@nbd.name>
* toolchain: gdb: Add optional python supportHauke Mehrtens2021-06-061-0/+8
| | | | | | | | | | | | | Compile gdb with python support optionally. To use the Python support in gdb some extra python files are needed, install them too. While at it also install other shared files which we did not install before. If gdb is built without Python support the python folder does not exists.

* toolchain: Fix glibc selection on ARC targetsHauke Mehrtens2020-12-231-0/+1
| | | | | | | | Without this change no libc is selected and the build will fail. This will select glibc for ARC CPUs. Fixes: 95f1002acab5 ("toolchain: default to glibc for ARC") Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de>
* toolchain: remove uClibc-ng config stuffRosen Penev2020-12-221-19/+0
| | | | | | This is in preparation for removing it. Signed-off-by: Rosen Penev <rosenp@gmail.com>
* toolchain: default to glibc for ARCRosen Penev2020-12-221-2/+1
| | | | | | | | glibc 2.32 gained support for the ARC architecture. This is preparation for removing uClibc-ng. Signed-off-by: Rosen Penev <rosenp@gmail.com>
* toolchain: remove gcc libssp and use libc variantIan Cooper2020-06-171-1/+1
| | | | | | | | | | | | | | | Removes the standalone implementation of stack smashing protection in gcc's libssp in favour of the native implementation available in glibc and uclibc. Musl libc already uses its native ssp, so this patch does not affect musl-based toolchains. Stack smashing protection configuration options are now uniform across all supported libc variants. This also makes kernel-level stack smashing protection available for x86_64 and i386 builds using non-musl libc. Signed-off-by: Ian Cooper <iancooper@hotmail.com>
* toolchain: Simplify libc selectionRosen Penev2019-10-211-2/+1
| | | | | | uClibc-ng is only needed for ARC. Simplify the conditions. Signed-off-by: Rosen Penev <rosenp@gmail.com>
* toolchain: Remove powerpc64 libc restrictionRosen Penev2019-08-051-4/+2
| | | | | | | | | | Starting with version 1.1.15, musl supports powerpc64. There are no known users of powerpc64 yet. This is effectively a revert of 0de93311e1575ab6f8e9e90b5023b6fb2cedcf1f Signed-off-by: Rosen Penev <rosenp@gmail.com>

* musl: improve crypt() size hackJo-Philipp Wich2019-01-221-0/+1
| | | | | | | | | | | | | | Instead of silently downgrading any non-MD5 crypt() request to DES, cleanly fail with return NULL and errno = ENOSYS. This allows callers to notice the missing support instead of the unwanted silent fallback to DES. Also add a menuconfig toolchain option to optionally disable the crypt size hack completely. This can be probably made dependant on SMALL_FLASH or a similar feature indicator in a future commit. Ref: https://github.com/openwrt/openwrt/pull/1331 Signed-off-by: Jo-Philipp Wich <jo@mein.io>
* toolchain: Replace YASM with NASMTed Hess2018-07-051-3/+3
| | | | | | | | | | Packages libx264 and ffmpeg are built with ASM options on x86 platforms. The current libx264 version no longer builds with YASM and requires NASM. ffmpeg 3.x can be built with either YASM or NASM however, furture 4.x versions will require NASM.

* toolchain: gdb: activate on ARM64Hauke Mehrtens2018-02-101-1/+0
| | | | | | | gdb supports ARM64 since quite some time now, activate it there like on other CPU architectures. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de>
* build: cleanup SSP_SUPPORT configure optionJulien Dusser2018-01-271-0/+4
| | | | | | | | | | | | | | | | | | Configure variable SSP_SUPPORT is ambiguous for packages (tor, openssh, avahi, freeswitch). It means 'toolchain supporting SSP', but for toolchain and depends it means 'build gcc with libssp'. Musl no longer uses libssp (1877bc9d8f), it has internal support, so SSP_SUPPORT was disabled leading some package to not use SSP. No information why Glibc and uClibc use libssp, but they may also provide their own SSP support. uClibc used it own with commit 933b588e25 but it was reverted in f3cacb9e84 without details. Create an new configure GCC_LIBSSP and automatically enable SSP_SUPPORT if either USE_MUSL or GCC_LIBSSP. Signed-off-by: Julien Dusser <julien.dusser@free.fr>
* toolchain: use glibc for powerpc64 buildsFlorian Larysch2017-10-241-3/+5
| | | | | | | Neither uClibc nor musl currently have working support for powerpc64 in big endian mode. Thus, default to using glibc for this architecture. Signed-off-by: Florian Larysch <fl@n621.de>
* toolchain: remove powerpc64 featureFlorian Larysch2017-10-241-3/+0
| | | | | | | | The powerpc64 feature flag was introduced with the PS3 support, which has been removed for quite a while and is now unused. Remove it and the special biarch handling it triggered during the toolchain build. Signed-off-by: Florian Larysch <fl@n621.de>
* toolchain/insight: Remove from treeDaniel Engberg2017-05-291-8/+0
| | | | | | | | Insight hasn't been touched since 2009 and I can't find any references at least 6 years back of being used. Ubuntu and Debian removed insight years ago from their repos so I think we can safely remove this too. Signed-off-by: Daniel Engberg <daniel.engberg.lists@pyret.net>

* toolchain: Rework external toolchain libc selectionFlorian Fainelli2016-09-281-3/+24
| | | | | | | | | | | | | | | | Make it a choice menu which offers the 3 C libraries we know about: glibc, uClibc and musl. While at it, make it possible for the external toolchain libc to select USE_GLIBC, USE_UCLIBC or USE_MUSL which is used by several packages to conditionally include specific CFLAGS (e.g: iproute2). Because USE_GLIBC et al. can now be selected by external toolchains, we need to restrict the per-libc menus to check on !EXTERNAL_TOOLCHAIN. While at it, make musl the default C library for external toolchain to match the internal toolchain. Signed-off-by: Florian Fainelli <f.fainelli@gmail.com> Signed-off-by: Felix Fietkau <nbd@nbd.name>
