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.

2017-01-22nds32: 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>

2015-02-20posix_fadvise: handle 2 variants for SYSCALL_ALIGN_64BITVineet Gupta
arm/powerpc/xtensa pass @advice as 2nd arg to syscall (vs. canonical 4th) Current code however does this for UCLIBC_SYSCALL_ALIGN_64BIT which powerpc/xtensa also happen to define. This is not true for ARCv2 ISA and possibly other arch of future with 64-bit even register requirement, which uses the standard syscall handler in kernel. Fix that by providing 2 variants of SYSCALL_ALIGN_64BIT Signed-off-by: Vineet Gupta <vgupta@synopsys.com> Cc: Baruch Siach <baruch@tkos.co.il> Cc: Max Filippov <jcmvbkbc@gmail.com> Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>
2014-08-18libc: posix_fadvise: Fix build breakage for !LFSVineet Gupta
commit 00571b43df2e "libc: posix_fadvise: restore implementation for xtensa" enabled posix_fadvise() for all arches (it was just not generated before). However this also unearthed an issue introduced by ee84b8b400 "linux: posix_fadvise: use new SYSCALL_ALIGN_64BIT" which is to referencing LFS'ish code (off64_t) w/o proper checks which causes build to break for !LFS. Fix this by calling posix_fadvise64() only for LFS case and open-code it's equivalent for !LFS.

2014-01-08libc: posix_fadvise: restore implementation for xtensaBaruch Siach
Commit ee84b8b400 (linux: posix_fadvise: use new SYSCALL_ALIGN_64BIT) removed posix_fadvise implementation for xtensa, since xtensa does not define __NR_fadvise64. Reuse the ARM support code to restore xtensa support. This commit is based Mike Frysinger's suggested patch.

2013-04-01linux: posix_fadvise: use new SYSCALL_ALIGN_64BITMike Frysinger
Now that we have a new SYSCALL_ALIGN_64BIT define for tracking the 64bit register shift behavior, use it. This allows us to delete duplicated arm/xtensa files, as well as drop a few arch ifdefs from common code. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2013-04-01linux: use OFF64_HI_LO rather than __LONG_LONG_PAIRMike Frysinger
This macro takes care of the shift/mask split for us, so no need to open code this ourselves and then use __LONG_LONG_PAIR. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2012-06-15posix_fadvise: make posix_fadvise[64] similar on all archsPeter S. Mazinger
Remove all versions, that can be covered by the common one. Drop incorrectly implemented fallback support, if __NR_fadvise64_64 is not available. To support 64 bit ppc, move ppc support into common. Cleanup including headers. Signed-off-by: Peter S. Mazinger <ps.m@gmx.net> Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>
2012-03-26stubs: unified from futureBernhard Reutner-Fischer
Future branch extends stubs with ret_enosys_stub. Resolve conflicts, and use superset of future and current master. Adjust posix_fadvise* accordingly. Upon future merge, pick this master version as the final state. Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>

Ports missing INLINE_SYSCALL() support need to get fixed, so drop the cruft keeping them alive since it no longer works with the unification. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

http://www.opengroup.org/onlinepubs/009695399/functions/posix_fadvise.html states it returns error code instead of setting errno.

Import INTERNAL_SYSCALL macro for i386 from glibc. Use above macro in posix_fadvise implementation if an arch defines it.
2006-12-08Take Mike Frysinger's comments into account -- make certain that userEric Andersen
applications stop using _syscall#() and use syscall() instead. Cleanup internal handling of syscall includes to use the correct header file.
