2010-02-09nptl: sysdep headers re-factoringCarmelo Amoroso
This patch will re-factor and simplify sysdep headers handling for nptl branch. The reason is to use some useful macros in asm code (i.e. ENTRY()) that are available only into nptl branch because are defined in sysdep.h header under the nptl folder even if they are not related to NPTL at all (this was likely due to a bad choice done at the early stage of NPTL porting). This is a required steps for integrating into master branch some asm code available in nptl branch for sh4. The main changes are described below: nptl/sysdeps/generic/sysdep.h (moved) ---> libc/sysdeps/linux/common/sysdep.h nptl/sysdeps/arm/sysdep.h (moved) ---> libc/sysdeps/linux/arm/sysdep.h nptl/sysdeps/sh/sysdep.h ---------------------| nptl/sysdeps/unix/sh/sysdep.h ----------------| nptl/sysdeps/unix/sysv/linux/sh/sysdep.h -----| nptl/sysdeps/unix/sysv/linux/sh/sh4/sysdep.h -| |(merged) ---> libc/sysdeps/linux/sh nptl/sysdeps/unix/sysdep.h (deleted) Similarly the mips and arm sysdep.h should be merged and updated as for sh arch.

2009-11-23bits/mmap.h: unify ala linux asm-generic effortsMike Frysinger
Most ports have the same exact mman bit defines, so let's unify things like the linux kernel has with the asm-generic efforts. A few ports are left behind as they are non-trivial to merge -- the arch maintainers can tackle it if they care. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2009-10-08Fix building arm EABIBernhard Reutner-Fischer
The syscall() impl on aeabi comes from syscall-eabi.S thus we do not need the generic syscall() impl. Fixes: AS libc/sysdeps/linux/arm/syscall-eabi.os CC libc/sysdeps/linux/common/syscall.os libc/libc_so.a(syscall.os): In function `syscall': syscall.c:(.text+0x0): multiple definition of `syscall' libc/libc_so.a(syscall-eabi.os):(.text+0x0): first defined here Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>

This reverts commit b1913a876059949e6c309bafade55e9425ef33fb. OABI is still a requirement. So we override the common syscall implementation specifically for arm port. Signed-off-by: Khem Raj <raj.khem@gmail.com>

2009-07-26enable nanosecond stat support for everyoneMike Frysinger
Fill out the stat structure so that the nanosecond resolution support is always available. There is a small code size increase for a few ports (three additional assignments in xstatconv), but otherwise everything should remain the same. While we're here, punt __old_kernel_stat from the few headers that still define it as it is unused in uClibc and causes compile errors after these nanosecond changes.

2009-07-14Fix ARM syscall argument loading.Joseph Myers
This patch is a uClibc equivalent of <http://sourceware.org/ml/libc-ports/2008-11/msg00006.html>, to compute all syscall arguments on ARM in temporary variables before loading them into register variables. The principle is as for that glibc patch; the problem I actually observed was a GCC internal compiler error building ld.so for Thumb-2. Signed-off-by: Joseph Myers <joseph@codesourcery.com>

2009-07-08syscall: unify common syscall definesMike Frysinger
Unify all the common syscall defines in syscalls-common.h and scrub all the duplicated code from relevant ports. This should also make converting existing ports to INLINE_SYSCALL() much easier as they don't have to get lost in all the unrelated noise, as well as creating new ports.

2009-07-05Avoid warnings about shifting more bits than we haveRon
The test here is a constant expression and will compile out. For platforms that don't need the shift the code gets slightly smaller and simpler, for those that do the result is unchanged. Signed-off-by: Ron Lee <ron@debian.org> Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2009-06-30Fix Thumb-2 setjmp.Joseph Myers
Many Thumb-2 instructions cannot use sp or pc as operands, and the assembler now diagnoses these. setjmp had one such instruction, movs; this patch changes it to mov. Signed-off-by: Joseph Myers <joseph@codesourcery.com>
2009-06-28Add missing CLIBABI variables __aeabi_stdin, __aeabi_stdout, __aeabi_stderr.Joseph Myers
The ARM EABI has a document CLIBABI specifying various __aeabi_* functions and variables to be provided for the use of portable objects that can be linked with different EABI-conforming C libraries. __aeabi_stdin, __aeabi_stdout and __aeabi_stderr were missing in uClibc; this patch (originally from Nathan Froyd and for glibc) adds them.

fix _NSIG for it. better document what's going on in sigaction(). seems to not induce any actual code changes (sans mips).
2008-11-25- Fix thumb2 PIE (Joseph S. Myers)Bernhard Reutner-Fischer
This patch fixes position-independent executables (PIEs) for Thumb-2. In Thumb assembly, instructions reading pc give a value 4 greater than the address of the instruction, rather than 8 greater as in ARM mode, so the offset to the GOT needs to have the right offset. (The Thumb-1 code already gets this right; it's the code shared by ARM and Thumb-2 that needs fixing.)
