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>
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.

2017-01-22nds32: add NPTL/TLS, *context function, libm changes and code cleanupVincent Ren-Wei Chen
This commit includes following features. 1. Support NPTL/TLS 2. Add libm function which is used to handle FP rounding and excpetions (ex: fclrexcpt,fedisblxcpti,feenablxcpt... ) 3. Add *context function for operating user context (ex: setcontext,getcontext,makecontext... ) 4. Change the return flow from signal handler 5. Cleanup of old code The testsuite only has 2 errors, tst-cpuclock1 and tst-cputimer1, which are related to timing accuracy. (math and locale tests are disabled) Signed-off-by: Vincent Ren-Wei Chen <vincentc@andestech.com>
2016-12-23remove UCLIBC_LINUX_MODULE_26Waldemar Brodkorb
The syscall wrappers are not required and other C libraries do not provide them. Busybox modutils.c must be patched so that syscall() is used for uClibc-ng. Signed-off-by: Waldemar Brodkorb <wbx@openadk.org>

A single test with targeting ARM showed that this feature seems bit rotted. Remove DOMULTI and simplify Makefiles.

2016-05-18remove linuxthreads.new, rename linuxthreads.oldWaldemar Brodkorb
Linuxthreads.new isn't really useful with the existence of NPTL/TLS for well supported architectures. There is no reason to use LT.new for ARM/MIPS or other architectures supporting NPTL/TLS. It is not available for noMMU architectures like Blackfin or FR-V. To simplify the live of the few uClibc-ng developers, LT.new is removed and LT.old is renamed to LT. LINUXTHREADS_OLD -> UCLIBC_HAS_LINUXTHREADS
2016-02-24ARC: Disable obstackAnton Kolesov
Obstack was enabled in ARC defconfig to enable builds of native binutils and GDB. This is not needed after earlier patch which removes invalid _GNU_OBSTACK_INTERFACE_VERSION definition in cases when obstack is not selected in uClibc configuration. With this change binutils and GDB would use obstack implementation from their own source trees. In fact with recent binutils it is not possible to build it using obstack implementation in uClibc, because binutils/include/obstack.h started to use _obstack_free function instead of obstack_free, but _obstack_free is not defined in uClibc.

2016-01-02remove deprecated architectures v850/i960Waldemar Brodkorb
Both architectures are more or less deprecated. No Linux upstream support, no gcc support for uClinux.

Get rid of NIOS support. We try to support NIOSII.
2015-12-05good by e1Waldemar Brodkorb
It is marked as broken and it seems you can't get any hardware for that anymore.
2015-12-05good bye vaxWaldemar Brodkorb
I mailed with Jan-Benedict Glaw, it seems VAX on Linux is really a lot of work todo and uClibc support didn't work ever.
2015-12-05remove sh64 supportWaldemar Brodkorb
No real hardware available. The project for sh64 with sh5 seems dead since 10 years. Gcc will remove support for it soon.

2015-02-16ARC: Conditionalise certain relocations as provided by TLS tools onlyVineet Gupta
uClibc mainline supports NPTL which in turns depends on TLS support in the tools (gcc/binutils), which is yet to be merged in dev branches. However there is some non NPTL code in uClibc, added as part of NPTL effort, which relies on certain relocations only provided by NPTL binutils. As a result building the current upstream even for LT.old breaks. So conditionalize that code on tools, bu tin lack of specific versions, we use NPTL enabling as a sign the tools are equipped to handle those relos.

2013-03-14Add support for the Meta architectureMarkos Chandras
Meta cores are 32-bit, hardware multithreaded, general purpose, embedded processors which also feature a DSP instruction set, and can be found in many digital radios. They are capable of running different operating systems on different hardware threads, for example a digital radio might run RTOSes for DAB decoding and audio decoding on 3 hardware threads, and run Linux on the 4th hardware thread to manage the user interface, networking etc. HTPs are also capable of running SMP Linux on multiple hardware threads.
