* Switch x86 syscall stubs over to the ENTER/END style of the ARM stubs.Elliott Hughes2013-02-06203-1218/+609
| | | | | | | | | Also update the x86 asm.h to support this; we need it for libm assembler anyway. Also clean up the _FBSDID hack in <sys/cdefs.h>. Change-Id: Iababd977b8110ec022bf7c93f4d62ece47630e7c
* Add signalfd call to bionicRom Lemarchand2013-01-101-0/+32
| | | | | | | | | | | | | | | | | | | Add signalfd() call to bionic. Adding the signalfd call was done in 3 steps: - add signalfd4 system call (function name and syscall number) to libc/SYSCALLS.TXT - generate all necessary headers by calling libc/tools/gensyscalls.py. This patch is adding the generated files since the build system does not call gensyscalls.py. - create the signalfd wrapper in signalfd.cpp and add the function prototype to sys/signalfd.h (cherry-pick of 0c11611c11f4dc1b6d43587b72c3ccbe8c51a51c, modified to work with older versions of GCC still in use on some branches.)

* Add getsid system call to bionicIrina Tirdea2012-09-031-0/+23
| | | | | | | | | | | | | | | | | | Add getsid() system call to bionic for all architectures. This is needed for various tools (e.g. perf). Adding the getsid system call was done in 3 steps: () add getsid system call (function name and syscall number) to libc/SYSCALLS.TXT () generate all necessary headers by calling libc/tools/gensyscalls.py. This patch is adding the generated files since the build system does not call gensyscalls.py. () add the system call signature to libc/include/unistd.h Change-Id: Id69a257e13ec02e1a44085a6b217a3f19ab025b1 Signed-off-by: Irina Tirdea <irina.tirdea@intel.com>

* libc: Add ftruncate64 and improve 64-bit parameter syscall handling.David 'Digit' Turner2010-12-163-6/+35
| | | | | | | | | | | | | | | This patch improves the handling of 64-bit parameters in syscalls on ARM. The ARM EABI mandates that 64-bit quantities be passed in even/odd register pairs, which requires special treatment. This allows us to simplify our implementations of pread() and pwrite() and remove the C stubs for pread64() and pwrite64(). Also add ftruncate64() to <unistd.h> Change-Id: I407e2fd223ba0093dd2d0b04c6152fadfc9ce3ef Bug 3107933
