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>
2017-02-13remove unused assignment in cloneWaldemar Brodkorb
Patch fetched from GNU libc mailinglist.
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.

2016-05-28sparc: remove unused 64 bit support codeWaldemar Brodkorb
2016-04-26sparc: add deprecated context switching functionsWaldemar Brodkorb
Ported over from glibc mostly without changes. Lightly tested with mongrel2 in qemu-system-sparc.
2016-01-02remove deprecated architectures v850/i960Waldemar Brodkorb
Both architectures are more or less deprecated. No Linux upstream support, no gcc support for uClinux.
2015-12-07add definitions for O_PATHWaldemar Brodkorb
Only alpha, hppa and sparc need non-default value.
2015-12-05good bye vaxWaldemar Brodkorb
I mailed with Jan-Benedict Glaw, it seems VAX on Linux is really a lot of work todo and uClibc support didn't work ever.
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.
2015-06-10siginfo: add signal info for seccomp related SIGSYSDaniel Golle
uClibc doesn't define signal info for the SIGSYS signal which is issued in case of hitting a syscall prohibited by seccomp. This is sad as it makes debugging seccomp filter policies impossible on some architectures (at least ARM and PowerPC, maybe also others) which do not coincidentally set si_value.sival_int as the syscall number. To fix this, import the definitions and macros needed from glibc. Signed-off-by: Daniel Golle <daniel@makrotopia.org> Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>

2014-09-04sparc: remove sparc64/sparcv9 codeWaldemar Brodkorb

2014-08-28Revert "sparc: use HIDDEN_JUMPTARGET for errno"Waldemar Brodkorb
This reverts commit f51fb26dbcceee9e48d10facc830bd4a549f6cc2. This fixes linking error for sparc build. While building a sparc system you get following linking error: libc/sysdeps/linux/sparc/pipe.S:54: undefined reference to `__GI___errno_location' Removing the HIDDEN_JUMPTARGET fixes the issue, while using gcc 4.8.3/binutils 2.24. The definition of __errno_location was changed recently here: http://git.uclibc.org/uClibc/commit/?id=8f550715c2b211036fc273add3cb5219397ed312 Signed-off-by: Waldemar Brodkorb <wbx@openadk.org> Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>

2014-08-20fix for pipe() on sparcWaldemar Brodkorb
When using something like this: $ echo foo|grep foo|wc -l with mksh shell, you get an runtime error. Glibc and klibc does not do these extra check.

2013-06-07eventfd.h: Use new "bits/" scheme for arch-specific flagsHiroaki KAWAI
As in timerfd.h, eventfd.h needs arch-specific definition files. alpha, mips and sparc needs separate file, all the other arch will use common definition. This problem is already fixed in glibc. Also sanitize and provide bits for hppa. Make sure not to install the new bits/eventfd unless eventfd support is enabled.

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.
