* INLINE_SYSCALL_NCS: scope out local vars to avoid conflictsMike Frysinger2009-08-191-6/+6
| | | | | | | | | | | | The INLINE_SYSCALL_NCS() macro was using "res" and "err" as local variable names, but this caused conflicts with some code (like clock_getres) whose arguments were named the same. libc/sysdeps/linux/common/clock_getres.c: In function 'clock_getres': libc/sysdeps/linux/common/clock_getres.c:15: warning: 'res' is used uninitialized in this function Signed-off-by: Mike Frysinger <vapier@gentoo.org> Signed-off-by: Austin Foxley <austinf@cetoncorp.com>
* fix building for systems w/out ldso supportMike Frysinger2009-08-191-1/+3
| | | | | | | | If an arch (like alpha and others) have no ldso support at all, then there is no point in attempting to walk loaded modules in the dl-* helper funcs. Signed-off-by: Mike Frysinger <vapier@gentoo.org> Signed-off-by: Austin Foxley <austinf@cetoncorp.com>
* alpha: fix building with no asm/elf.hMike Frysinger2009-08-191-1/+14
| | | | | | | | The latest sanitized linux kernel headers no longer export asm/elf.h, so do not rely on it anymore. Signed-off-by: Mike Frysinger <vapier@gentoo.org> Signed-off-by: Austin Foxley <austinf@cetoncorp.com>

* first pass at implementing *at funcsMike Frysinger2009-08-1918-18/+370

* fdatasync: handle latest alpha syscallsMike Frysinger2009-08-191-1/+1
| | | | | | | | The latest alpha Linux kernel defines __NR_fdatasync like everyone else and deprecates the older __NR_osf_fdatasync, so support that setup. Signed-off-by: Mike Frysinger <vapier@gentoo.org> Signed-off-by: Austin Foxley <austinf@cetoncorp.com>
* dirent: push dirent type to prototypesMike Frysinger2009-08-196-32/+12
| | | | | | | | | | | This syncs the dirent related functions with the glibc behavior -- rather than take void pointers everywhere, make the struct dirent pointers explicit in the API. After all, the functions themselves will cast the pointers to a dirent structure, so if it isn't as expected, people will crash.

* Fix ARM syscall argument loading.Joseph Myers2009-08-191-14/+21
| | | | | | | | | | | | 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.

* drop missing {INLINE,INTERNAL}_SYSCALL fallback logicMike Frysinger2009-07-098-102/+0
| | | | | | | | 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> Signed-off-by: Austin Foxley <austinf@cetoncorp.com>
* syscall: unify common syscall definesMike Frysinger2009-07-0914-1061/+316
| | | | | | | | | | 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.

* i386: store errno value before using __set_errno()Ingo van Lil2009-07-091-4/+3
| | | | | | | | | | | | The __syscall_error() function stores the errno value in the edx register before invoking the __set_errno() macro. When using the pthread library this macro calls thread_self() to determine the errno location, which might clobber the edx register. The errno value must be stored in a "real" variable so the compiler can take care of saving/restoring it if necessary.

* Correct ARM memcpy comments.Joseph Myers2009-07-091-1/+2
| | | | | | | | | The comments on register usage in ARM memcpy had dest and src the wrong way round; this patch (originally from Mark Shinwell) corrects this and adds a note on the return value.

* Fix Thumb-2 setjmp.Joseph Myers2009-07-091-1/+1
| | | | | | | | | 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> Signed-off-by: Austin Foxley <austinf@cetoncorp.com>
* Fix Thumb-2 memcpy.Joseph Myers2009-07-091-1/+1
| | | | | | | | | | When an IT block was changed from having two instructions to having one, the IT instruction at the start of the block was not updated, causing memcpy to fail to assemble for Thumb-2; this patch makes the obvious fix.

* Add missing CLIBABI variables __aeabi_stdin, __aeabi_stdout, __aeabi_stderr.Joseph Myers2009-07-091-0/+15
| | | | | | | | | | | | 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.
