2016-11-13ARC: string: handle gcc 6.x macro changesVineet Gupta
In gcc 6.x cleanup, the macros got renamed. (Need to support the old toggle for some more time) Signed-off-by: Vineet Gupta <vgupta@synopsys.com>
2016-11-10nptl: add pthread_getname_np/pthread_setname_np from GNU libcWaldemar Brodkorb
These functions are used by firefox for example. Tested with running firefox on x86 system.
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.

2016-10-31ldso: remove useless debug output, too much noiseWaldemar Brodkorb
2016-10-28test: remove test suiteWaldemar Brodkorb
The test suite is now a developed in a separate git repository. See here: http://cgit.uclibc-ng.org/cgi/cgit/uclibc-ng-test.git The test suite should be just like every other software compiled with the cross-toolchain. In the past strange problems where found when the test suite got build in the toolchain creation step.
2016-10-24linuxthreads: add back signal.hWaldemar Brodkorb
Somehow this got removed with f1d7505e40654a185843bdc8f1cf1fd00ab55c04. Reported-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>

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>

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.

There was a deadlock hanging in a sycall to futex, which should be solved now. Signed-off-by: Waldemar Brodkorb <wbx@uclibc-ng.org>

2016-10-08ppc: do not include copysgnl.c if UCLIBC_HAS_LONG_DOUBLE_MATH enabledWaldemar Brodkorb
Fixes compilation of uClibc-ng when UCLIBC_HAS_LONG_DOUBLE_MATH is used.
2016-10-08cleanup libc.aWaldemar Brodkorb
The nested libpthread_nonshared.a and libdl.os shouldn't be included in the static libc.a. Fixes compile issues for static builds.
2016-10-06test: fix tests including non-wrapper libgcc exception handling codeWaldemar Brodkorb
The tests shouldn't include libgcc exception handling functions directly from libgcc.a when a non-shared gcc compiler is used while compiling the testcases. These fixes open testsuite regressions found for ppc and xtensa.

2016-09-26use a single libc and deduplicate threading codeWaldemar Brodkorb
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

2016-09-26linuxthreads: use tkill syscall for raiseWaldemar Brodkorb
Seems better and more stable.
2016-09-26always assume tgkill is presentWaldemar Brodkorb
We do not support 2.4 Linux kernels anyway, and almost all newer 2.6 kernels should have tgkill syscall. Cleanup the raise situation, pt-raise.c is unused, sync raise.c with latest GNU libc. Signed-off-by: Waldemar Brodkorb <wbx@uclibc-ng.org>

2016-09-19test: disable regex testsWaldemar Brodkorb
The time to run the tests is very high and always subtests are failing. We need to fix the subtests and see how to reduce the time the test is running. At the moment it blocks my regression testing to much.
2016-09-19elf-{fdpic, dsbt}.h: avoid void pointer's subtractionRahul Bedarkar
elf-fdpic.h or elf-dsbt.h is included by link.h. When C++ program includes <link.h>, we get following build failure. ../usr/include/bits/elf-fdpic.h: In function 'void* __reloc_pointer(void*, const elf32_fdpic_loadmap*)': ../usr/include/bits/elf-fdpic.h:95: error: invalid use of 'void' void pointer addition and subtraction is not allowed in C++ as it has undetermined size, however in C with language extension it is possible because sizeof void is treated as one byte. Instead of performing subtraction on void pointers, typecast it to char* first. This build failure is detected by Buildroot autobuilder. http://autobuild.buildroot.net/results/a10/a10ed48e6eb8411a3d8372f57c05fd11130da0e0/ Signed-off-by: Rahul Bedarkar <rahul.bedarkar@imgtec.com>

A single test with targeting ARM showed that this feature seems bit rotted. Remove DOMULTI and simplify Makefiles.
2016-08-27ARC: Fix max ULP for cosine testEugeniy Paltsev
Max ULP for "cos (M_PI_6l * 2.0) == 0.5" in "test-double" sub-test is set to "0" for ARC. It causes "test-double" test failure. I realized that this sub-test on ARM gets completely same results. But it doesn't fails on ARM because max ULP is set to "1" for ARM. I am wondering, if it was done for any special reason? Otherwise, set max ULP for "cos (M_PI_6l * 2.0) == 0.5" test to "1" instead of "0" for ARC. Signed-off-by: Eugeniy Paltsev <Eugeniy.Paltsev@synopsys.com>

Add -Wdeclaration-after-statement when EXTRA_WARNINGS is enabled.
2016-08-17ARC: Support syscall ABI v4Vineet Gupta
The syscall ABI includes the gcc functional calling ABI since a syscall implies userland caller and kernel callee. The current gcc ABI (v3) for ARCv2 ISA required 64-bit data be passed in even-odd register pairs, (potentially punching reg holes when passing such values as args). This was partly driven by the fact that the double-word LDD/STD instructions in ARCv2 expect the register alignment and thus gcc forcing this avoids extra MOV at the cost of a few unused register (which we have plenty anyways). This however was rejected as part of upstreaming gcc port to HS. So the new ABI v4 doesn't enforce the even-odd reg restriction. Do note that for ARCompact ISA builds v3 and v4 are practically the same in terms of gcc code generation. This change is dormant for now (gcc 4.8.x based tools) and will only kick in with switch to gcc 6.x based tools. Signed-off-by: Vineet Gupta <vgupta@synopsys.com>
2016-08-16linuxthreads: install libpthread_nonshared.aWaldemar Brodkorb
This is useful to build native gcc on targets supporting Linuxthreads instead of NPTL.
