2017-12-31m68k: add NPTL/TLS supportWaldemar Brodkorb
Port over NPTL/TLS support from GNU C Library. In the first step only the slower syscall is used for TLS access. The uClibc-ng testsuite shows 79 errors, so their is room for bugfixes and improvements.
2017-12-26csky: remove -mcpu and -mhard-float from configGuo Ren
Pass the -mcpu and -mhard-float from UCLIBC_EXTRA_CFLAGS instead. Signed-off-by: Guo Ren <ren_guo@c-sky.com>
2017-12-03fenv: only allow to enable for supported architecturesWaldemar Brodkorb
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.

2017-08-20arc: Merge ARCv2 string routines in generic ARC .S filesAlexey Brodkin
In cde74b83f9b2 "ARC: remove special CFLAGS/LDFLAGS handling" we got rid of CONFIG_ARC_CPU_HS which was used to select ARCv2-specific implementation of optimized string routines. So now ARCv2-tuned memset/memcpy/strcmp are not used, instead those for ARC700 used for both ARC700 and ARCHS. Without uClibc config option we may only tell which CPU type we're targeting by built-in defines of GCC. I.e. no more conditional file inclusion in Makefiles. That leaves us only one option - merge both implementations in 1 file and use ifdefs. Signed-off-by: Alexey Brodkin <abrodkin@synopsys.com>
2017-06-23sparc64: add basic supportWaldemar Brodkorb
No NPTL, no LDSO support. Bootup with Busybox Ash in Qemu working. Testuite shows only two failures, but mksh continue/break support doesn't work.

2017-04-16libm: allow long double wrappers for all architecturesWaldemar Brodkorb
If you enable these wrappers, be sure you don't need long double precision on your embedded device, as these only enables long double warpper functions to the existing double math functions. Required to build some software as lvm2. Signed-off-by: Waldemar Brodkorb <wbx@uclibc-ng.org>

2017-03-21ARC: remove special CFLAGS/LDFLAGS handlingWaldemar Brodkorb
Either toolchain defaults or buildsystems should provide the architecture specific CFLAGS and LDFLAGS.
2017-03-20remove RPC implementationWaldemar Brodkorb
The included RPC implementation is ipv4 only. Other C library projects have either deprecated the internal RPC implementation (GNU C Library) or never implemented such functionality (musl C Library). The latest rpcbind release (0.2.4) checks for libtirpc and does not allow to be build with uClibc-ng RPC without patching. The common use case for RPC nowadays is to use rpcbind together with nfs-utils to provide NFS server or client support to a system. The included RPC implementation does create issues with duplicate symbol failures when statically compiling with RPC enabled.
2017-02-01add experimental aarch64 supportWaldemar Brodkorb
Ported over from GNU C Library and runtime tested in Qemu.

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>
2016-12-21remove obstack supportWaldemar Brodkorb
Remove __UCLIBC_HAS_OBSTACK__ as it isn't very uptodate and maintained part. It shouldn't be required for any software and mostly shipped with stuff which use it. (f.e. binutils-gdb)
2016-12-20remove __MALLOC_GLIBC_COMPAT__ optionWaldemar Brodkorb
This option is enabled for a long time and I see no useful case where we should be incompatible to glibc here.
2016-12-20add stub implementation for libintl/gettextWaldemar Brodkorb
These adds the stubs from gettext-tiny 0.0.5 from here: https://github.com/sabotage-linux/gettext-tiny
2016-12-14add libiconv-tiny implementationWaldemar Brodkorb
To use it enable UCLIBC_HAS_LIBICONV, then iconv_open/iconv_close should be available.

2016-11-04nios2: sync support with glibcWaldemar Brodkorb
Only static linking is supported for now. More debugging and analyzing for ld.so, TLS and NPTL is required. But at least you can bootup a static root fileystem in Qemu.
2016-11-03microblaze: add NPTL/TLS support from GNU libcWaldemar Brodkorb
Not perfect, but a starting point. Some tests of the test suite are failing.
2016-10-16linuxthreads: allow to choose on all supported architecturesWaldemar Brodkorb
To analyze or debug any linuxthreads problems it is useful to have the ability to have a full gdb on the target available. At the moment you could only debug stuff on microblaze. Now we can verify that linuxthreads are working fine for every supported architecture.

2016-08-27remove DOMULTI supportWaldemar Brodkorb
A single test with targeting ARM showed that this feature seems bit rotted. Remove DOMULTI and simplify Makefiles.
2016-08-25mips: add NaN supportWaldemar Brodkorb
2016-06-30nds32: add support for new architectureWaldemar Brodkorb
Add support for Andes Technology NDS32 architecture. See here http://www.andestech.com/en/index/index.htm for more informaton. Verification of the port from an older uClibc port was done on a sponsored AG101p board. The testsuite only has 5 errors, three are related to an existing bug in dlclose() with LT.old, also happening on cris32 and m68k. Failures to fallocate/posix_fallocate are unresolved. Thanks to Andes Technology sponsoring the hardware and being very helpful while doing the uClibc-ng porting. Signed-off-by: Waldemar Brodkorb <wbx@uclibc-ng.org>

2016-05-29mips: allow to disable prefetch support in memcpy/memsetWaldemar Brodkorb
There exist some problem with the new memcpy/memset functions imported from GNU libc/newlib. If you have any problem with the new MIPS optimized assembly try to disable prefetching support. Thanks to Rene Nielsen and Matthew Fortune analyzing the problem so far.
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
2016-04-26sparc: add deprecated context switching functionsWaldemar Brodkorb
Ported over from glibc mostly without changes. Lightly tested with mongrel2 in qemu-system-sparc.
2016-03-31arm: simplify handling of Thumb related optionsThomas Petazzoni
Currently, the Thumb support on ARM has three related Config.in options, which are not trivial for users to understand, and are in fact not needed: - The USE_BX option is not needed: knowing whether BX is available or not is easy. If you have an ARM > v4 or ARMv4T, then BX is available, otherwise it's not. This is the logic used in glibc. - The USE_LDREXSTREX option is not needed: whenever Thumb2 is available, ldrex/strex are available, so we can simply rely on __thumb2__ to determine whether ldrex/strex should be used, without requiring a Config.in option. - Once USE_BX and USE_LDREXSTREX are removed, the only thing left that COMPILE_IN_THUMB does is to set -mthumb. This makes the option unnecessary, as on ARM at least, the user is already supposed to pass -march=<foo> or other compiler options tuning the library for a specific ARM variant. There is no reason to do otherwise for Thumb, which allows to get rid of the COMPILE_IN_THUMB option. Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>
2016-03-26frv: enable in configWaldemar Brodkorb
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.

2016-02-07frv: resurrect port somehow, totally untestedWaldemar Brodkorb
The FR-V port is really broken, and I have no emulator or hardware for this platform. I tried to get some hardware from RedHat, who made the FR-V port initially. Unfortunately Fujitsi didn't agreed to sent me some of their unused spare hardware lying @RedHat. As I invested some time to get stuff compiled, I decided to add the code and may be anytime later I can gain access to some emulator or hardware. GDB simulator for FR-V doesn't support booting Linux AFAIK.
2016-01-27nios2: allow to build toolchainWaldemar Brodkorb
At least allow to compile a toolchain targeting nios2 without MMU.
