2020-08-11xtensa: add exclusive access supportMax Filippov
Add XCHAL definitions for S32C1I and EXCLUSIVE options to xtensa-config.h, include it in places that implement atomic operations and add implementations with exclusive access option opcodes. Signed-off-by: Max Filippov <jcmvbkbc@gmail.com>
2020-08-11xtensa: relax memory constraint in atomic assemblyMax Filippov
Replace "a" constraints with "+m" to avoid forcing atomic variable address into a register and let the compiler use non-zero offset in load/store opcodes. Signed-off-by: Max Filippov <jcmvbkbc@gmail.com>
2018-04-22linuxthreads: implement pthread_condattr_{s,g}etclock()Waldemar Brodkorb
More applications are using pthread_condattr_setclock()/ pthread_condattr_getclock() in their code. Port these two functions from NPTL over to be more compatible.
2018-01-03fdpic: fix ld.so crashingWaldemar Brodkorb
Newer binutils is creating a section INIT_ARRAY from any .init_array and .ctors in the code. When ld.so runs initialization functions for loaded objects with _dl_run_init_array() it crashes on Bfin FDPIC system. It is trying to execute the function in pthread.c, which is no longer useful with the combined C library approach. Gcc -Wl,-M debugging output was very useful to find the reason for the INIT_ARRAY section.
2017-11-19linuxthreads: add dummy for pthread_atforkWaldemar Brodkorb
For noMMU targets we need a pthread_atfork dummy, otherwise libraries like libressl using pthread_atfork, but not fork() for itself, can not be used. But software like curl with ssl support linking against libressl still work fine on noMMU targets.

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.
2017-01-22nds32: 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>

2016-11-17libpthread: remove pthread_atfork for noMMU targetRomain Naour
There is not possible to use use fork() on noMMU target, so exporting pthread_atfork() for such target is useless. A program using pthread_atfork() will likely fail at runtime due to the error code returned by this function. Signed-off-by: Romain Naour <romain.naour@gmail.com>
2016-10-24linuxthreads: add back signal.hWaldemar Brodkorb

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

2016-08-16linuxthreads: install libpthread_nonshared.aWaldemar Brodkorb
This is useful to build native gcc on targets supporting Linuxthreads instead of NPTL.
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>
2016-06-23libs: install backward compatibility symlinksAlexey Brodkin
Simplify the switch from uClibc to uClibc-ng. Apps already built against uClibc-0.9.x.y require .so.0 libs to present on target which in case of current uClibc-ng is not the case and those apps could not be run. This change creates symlinks from .so.1 to .so.0 for most of other libs in the same way as it was done by 23e96d89b6ab "ldso: install backward compatibility symlink by default" Signed-off-by: Alexey Brodkin <abrodkin@synopsys.com> Cc: Waldemar Brodkorb <wbx@uclibc-ng.org> Cc: Vineet Gupta <vgupta@synopsys.com> Cc: Anton Kolesov <akolesov@synopsys.com>
2016-05-31linuxthreads.old: Fix segfault when pthread_mutex_unlock() called against ↵Leonid Lisovskiy
unlocked NORMAL mutex. Althought, it is undefined behavior, there is no reason for segfault. Program received signal SIGSEGV, Segmentation fault. __pthread_unlock (lock=lock@entry=0x804b03c <lock+16>) at libpthread/linuxthreads.old/spinlock.c:231 231 (&lock->__status, oldstatus, (long)(thr->p_nextlock) & ~1L)) It occurs only on platforms which has HAS_COMPARE_AND_SWAP defined.

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.

2012-11-18drop support for pre ISO-C compilersMike Frysinger
This drops __signed, __volatile, and __const. Only the latter was used in the code base, and for uClibc, not consistently. Much of the code used plain "const" which meant "__const" was useless.
