2017-06-08fcntl.h: fixup namespace for O_DIRECTORY/O_NOFOLLOW/O_CLOEXECWaldemar Brodkorb
Sync with GNU C library. Found while trying to compile linux-rdma to uClibc-ng. Reported-by: Alexey Brodkin <Alexey.Brodkin@synopsys.com>
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.

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.

Remove powerpc64 bits as we only support powerpc32.

2016-07-17cleanup PTR_MANGLE/PTR_DEMANGLE supportWaldemar Brodkorb
As this is only implemented for a few architecture and not well tested, just remove it. Reviewed-by: Max Filippov <jcmvbkbc@gmail.com>
2016-06-03ppc: cleanup unsupported ppc64 codeWaldemar Brodkorb
Remove ppc64 bits and bytes, as we don't support ppc64 and it makes the code more readable without the dead code.

2015-12-05remove __UCLIBC_ASM_GLOBAL_DIRECTIVE__Waldemar Brodkorb
.globl can be used for every architecture so remove the define. Sync with GNU C library.
2015-12-05remove __UCLIBC_HAVE_ASM_GLOBAL_DOT_NAME__Waldemar Brodkorb
It's even no longer required for non-ported ppc64 architecture. Sync with GNU C library. This simplify the macros in include/libc-symbols.h.

2013-04-01linux: pread/write: convert to SYSCALL_ALIGN_64BITMike Frysinger
The pread64/write64 syscalls have the 64bit register align issue for all arches. Use this new define so we can merge the powerc/xtensa versions back into the common code. SuperH is funky and also allows us to do this. We should be able to merge the mips version too, but that'll require someone to take a closer look as the current stuff doesn't look quite right. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2013-04-01libc: rename TRUNCATE64_HAS_4_ARGS to SYSCALL_ALIGN_64BITMike Frysinger
The reason truncate64 takes 4 args on some arches is that their ABI requires 64bit values to be aligned on register pair boundaries. Since this alignment affects more than just truncate64, rename the define to properly document its purpose. This also allows us to expand it to the other impacted syscalls (which will be done in a follow up commit). Signed-off-by: Mike Frysinger <vapier@gentoo.org>

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. Really, the point of this is to stay in sync with what glibc did. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2012-10-02libc/sysdeps: add __kernel_long and __kernel_ulongChris Packham
Linux 3.4 added __kernel_long_t and __kernel_ulong_t and various exported header files were updated to use these new types. Add the definitions for __kernel_long_t and __kernel_ulong_t to the relevant kernel_types.h headers. This change was automated with the following scriptlet git grep --name-only 'typedef.*__kernel_old_dev_t' \ | xargs sed -i '/typedef.*__kernel_old_dev_t/ a\ typedef long\t\t__kernel_long_t;\ typedef unsigned long\t__kernel_ulong_t;' Whitespace in arm, avr32, hppa, sparc was then manually fixed up. Signed-off-by: Chris Packham <chris.packham@alliedtelesis.co.nz> -- Here's a cleaned up patch which should get the whitespace right. I'm a bit iffy about the sparc changes they make sense to me but it's not a platform I have access to.
