2022-11-20RISC-V 32-bit supportustcymgu@gmail.com
Added 32-bit RISC-V support. I have managed to get 32-bit RISC-V No-MMU Linux running based on mainstream buildroot. It's nice to have uclibc support this 32-bit No-MMU target. There's no substantial code change except definations and config options. Signed-off-by: Yimin Gu <ustcymgu@gmail.com>

2021-06-04powerpc: fix PIE/PIC builds with newer gcc/binutils which use secureplt by ↵Yann Sionneau
default This patch fixes segfault of all user space processes (including init, which caused a panic) on recent buildroot powerpc32 builds. The issue has been reported by Romain Naour in this thread: https://mailman.uclibc-ng.org/pipermail/devel/2021-May/002068.html Recent buildroot toolchain enables secure PLT in powerpc gcc. The latter will then supply -msecure-plt to gas invocations by default. Recent buildroot also enables PIE by defaults. For the secure PLT to work in PIC, the r30 register needs to point to the GOT. Old "bss plt" was just a one-instruction-wide PLT slot, pointed-to by a R_PPC_JMP_SLOT relocation, which was written on-the-fly to contain a branch instruction to the correct address. It therefore had to stay writable. New secure PLT only contains read-only code which loads the branch address from the writable GOT. Note: secure PLT without PIC does not need r30 to be set. Because offset between plt stub code and got is known at link-time. In this case the PLT entry looks like: 1009b3e0 <__uClibc_main@plt>: 1009b3e0: 3d 60 10 0e lis r11,4110 1009b3e4: 81 6b 03 74 lwz r11,884(r11) 1009b3e8: 7d 69 03 a6 mtctr r11 1009b3ec: 4e 80 04 20 bctr Whereas secure PLT with PIC - offset between plt and got is unknown at link-time - looks like this: 000af800 <00000000.plt_pic32.__uClibc_main>: af800: 81 7e 03 80 lwz r11,896(r30) af804: 7d 69 03 a6 mtctr r11 af808: 4e 80 04 20 bctr af80c: 60 00 00 00 nop Signed-off-by: Yann Sionneau <yann@sionneau.net>

2020-10-02kvx: add support for kvx arch to uClibc-ngYann Sionneau
This commit adds support for Kalray VLIW family (kvx) Kalray kv3 core is embedded in Kalray Coolidge SoC. This core which is the third of the KV family has the following features: 32/64 bits execution mode 6-issue VLIW architecture 64 x 64bits general purpose registers SIMD instructions little-endian In order to build a usable toolchain, build scripts are provided at the following address: https://github.com/kalray/build-scripts. Kalray uses FOSS which is available at https://github.com/kalray This includes Linux kernel, uClibc-ng, gcc, binutils, etc. Signed-off-by: Clément Léger <cleger@kalray.eu> Signed-off-by: Guillaume Thouvenin <gthouvenin@kalray.eu> Signed-off-by: Laurent Thevenoux <lthevenoux@kalray.eu> Signed-off-by: Marc Poulhies <mpoulhies@kalray.eu> Signed-off-by: Marius Gligor <mgligor@kalray.eu> Signed-off-by: Yann Sionneau <ysionneau@kalray.eu>

2020-04-27Rules.mak: Fix check_as for recent binutils versionsMarcel Patzlaff
As described in https://bugs.busybox.net/show_bug.cgi?id=12801 the check for '-Wa,--noexecstack' is not working since binutils 2.31.x. This fix adapts the approach already taken with check_ld and uses a temporary file. Further, check_gcc is also adapted to avoid future problems. Signed-off-by: Marcel Patzlaff <m.patzlaff@pilz.de>

2017-11-19csky: port to uclibc-ngGuo Ren
Follow the steps to build c-sky uclibc linux system: 1. git clone https://github.com/c-sky/buildroot.git 2. cd buildroot 3. make qemu_csky_ck810_uclibc_defconfig 4. make Follow the buildroot/board/qemu/csky/readme.txt to run. This buildroot toolchain is pre-build, But you can rebuild the c-sky uclibc-ng alone and install it to the buildroot sysroot manually. We'll try our best to improve the uclibc-ng continuously.

2016-10-22ARC: build: don't force usage of llock and swape instructionsVineet Gupta
This is because some old ARC750 cores lack these instructions. We now rely on the default for the toolchain driver: -mcpu=A7 won't enable those, while -mcpu=archs will as these instructions are baseline (and thus is not impacted with this change). If some arc700 based cpu does have them, it can override the driver defaults in it's one level up build system. Signed-off-by: Vineet Gupta <vgupta@synopsys.com>

Similar to musl libc a single libc has many benefits and solves some open issues with uClibc-ng. - no pthread_mutex_* weak symbols exported anymore - applications no longer failing to link when either -lrt or -lpthread are missing for dynamic and static linking mode - smaller C library - slightly better runtime performance
