2016-11-29libpthread: Fix inclusion of unwind code.Ignacy Gawędzki
Since librt and libpthread are now integrated into libc, including unwind-resume and unwind-forcedunwind implementations of unwind code makes no sense. Only unwind-forcedunwind is now included with functions hidden to avoid them overriding the ones from libgcc_s. * libpthread/nptl/sysdeps/generic/unwind-resume.h: New. Define generic PERSONALITY_PROTO and PERSONALITY_ARGS and set HAVE_ARCH_UNWIND_RESUME to 0. * libpthread/nptl/sysdeps/pthread/unwind-resume.c: Move... * libpthread/nptl/sysdeps/generic/unwind-resume.c: ... here. Include generic implementation of _Unwind_Resume on the condition that !HAVE_ARCH_UNWIND_RESUME. Make functions hidden to prevent them from overriding libgcc_s's ones. * libpthread/nptl/sysdeps/pthread/unwind-forcedunwind.c: Likewise. * libpthread/nptl/sysdeps/arm/unwind-resume.h: New. Define ARM-specific PERSONALITY_PROTO and PERSONALITY_ARGS and set HAVE_ARCH_UNWIND_RESUME to 1. * libpthread/nptl/sysdeps/arm/arm-unwind-resume.c, * libpthread/nptl/sysdeps/arm/pt-arm-unwind-resume.c, * libpthread/nptl/sysdeps/arm/rt-arm-unwind-resume.c: New. ARM-specific implementations of _Unwind_Resume resp. for libc, libpthread and librt. * libpthread/nptl/sysdeps/Makefile.commonarch: Remove both arm-unwind-resume and rt-arm-unwind-resume from libpthread_arch_CSRC. * libpthread/nptl/sysdeps/unix/sysv/linux/arm/unwind-forcedunwind.c, * libpthread/nptl/sysdeps/unix/sysv/linux/arm/unwind-resume.c: Remove.

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>
2016-11-17Fix extra/locale/gen_wc_8bit error with out-of-tree buildsAnton Kolesov
If uClibc is built outside of the source tree, then there is an error: make[1]: *** No rule to make target `/home/akolesov/build-uclibc/extra/locale', needed by `/home/akolesov/build-uclibc/extra/locale/gen_wc8bit'. Stop. The rule to create $(top_builddir)/extra/locale is defined in top-level Makefile.in. Same Makefile.in also invokes extra/locale/Makefile.in to build various tools. Those tools have $(top_builddir)/extra/locale as a dependency, but this makefile doesn't include top-level Makefile.in, therefore rule to create dependant directory is absent in this submake invocation. To avoid this problem this patch defines $(top_builddir)/extra/locale as a dependency for "headers" target, which invokes extra/locale/Makefile.in, thus making sure that prerequisite directory is created in advance. This problem doesn't occur when building in the source tree, since $(top_builddir) == $(top_srcdir), so this directory already exists. Signed-off-by: Anton Kolesov <Anton.Kolesov@synopsys.com>

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.

2016-11-04nios2: 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.

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.

2016-10-22ARC: 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>
