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>

2017-01-28remove PID cachingWaldemar Brodkorb
Follow GNU C Library from c579f48edba88380635ab98cb612030e3ed8691e and remove the PID caching. These simplifies the architecture specific assembly code. The run of the test suite found no regressions, it even solves some of the test failures for x86/x86_64/sparc.

2017-01-28mips: PROF is never defined, kill dead codeWaldemar Brodkorb
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>

Add the wrappers unconditionally, because kmod package still uses them.
2016-12-26mips: use the common dirent.hWaldemar Brodkorb
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>

2016-11-13NPTL/ARC: provide a kernel assisted atomic cmpxchgVineet Gupta
For hardware configurations lacking LLOCK/SCOND (say ARC750), use a syscall to atomically do the cmpxchg. This is costly and painful, but really the only way out.

2016-11-13NPTL/ARC: implement __arch_exchange_32_acq using native EXVineet Gupta
ARC EX instruction maps directly to this primitive, thus helps elide the llock/scond based retry loop where possible. 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.

2016-09-26use 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
2016-09-26always 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>

2016-09-19elf-{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>
