* MIPS: restore INLINE_SYSCALL macroGabor Juhos2010-04-271-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The MIPS specific INLINE_SYSCALL macro has been renamed to INLINE_SYSCALL_NCS with: 763bbf9e9a27426c9be8322dca5ddf2cb4dbc464 syscall: unify part 2: NCS variety Declare common NCS (non-constant syscall) variants and convert the existing ports over to this. This change breaks system calls. The code generated with using of the new macro does not obey the restartable syscall convention used by the linux kernel. When it tries to restart the syscall the errno value is not being replaced by the syscall number. This causes weird behaviour of the 'ping' command in busybox for example: root@OpenWrt:/# ping 192.168.1.254 PING 192.168.1.254 (192.168.1.254): 56 data bytes 64 bytes from 192.168.1.254: seq=0 ttl=128 time=6.292 ms ping: recvfrom: Function not implemented 64 bytes from 192.168.1.254: seq=1 ttl=128 time=0.719 ms ping: recvfrom: Function not implemented 64 bytes from 192.168.1.254: seq=2 ttl=128 time=0.489 ms ping: recvfrom: Function not implemented 64 bytes from 192.168.1.254: seq=3 ttl=128 time=0.486 ms ping: recvfrom: Function not implemented 64 bytes from 192.168.1.254: seq=4 ttl=128 time=0.487 ms ping: recvfrom: Function not implemented 64 bytes from 192.168.1.254: seq=5 ttl=128 time=0.939 ms ping: recvfrom: Function not implemented 64 bytes from 192.168.1.254: seq=6 ttl=128 time=0.971 ms ping: recvfrom: Function not implemented 64 bytes from 192.168.1.254: seq=7 ttl=128 time=0.488 ms ping: recvfrom: Funct^C Signed-off-by: Gabor Juhos <juhosg@openwrt.org> Signed-off-by: Austin Foxley <austinf@cetoncorp.com>
* mips: do not save variables in "hi" or "lo" across system callsDaniel Jacobowitz2009-09-261-2/+2
| | | | | | | | | The kernel does not save these registers across system calls. GCC 4.4 has gotten more aggressive about using them for temporary variables, so this shows up as intermittent crashes if you use a recent compiler.

* syscall: unify common syscall definesMike Frysinger2009-07-081-67/+0
| | | | | | | | | 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.

| | | | | | | | | | | | | | | When I imported INLINE_SYSCALL, etc. from glibc, I just copied whole macros for each ABI. Actually, except for argument type (long vs. long long), internal_syscall[0-4] are identical for all ABI, and internal_syscall[5-6] for N32/N64 are identical for N32/N64. And I just disabled FORCE_FRAME_POINTER since it had caused build failure, but including <alloca.h> can solve it. Here is a patch to handle these issues, plus asm/__asm__ and volatile/__volatile__ conversion. Thanks for Peter S. Mazinger who did basic work of this cleanup.

| | | | | | | | This patch imports INLINE_SYSCALL, etc. from glibc-2.5 ports and implements _syscall[0-7] by using them, like arm and powerpc. I think this patch does not change functionality, but gives better __SYSCALL_CLOBBERS for N32/N64.

| | | | | | | | | In a recent post to linux-mips ML (and libc-alpha ML), a problem with inline syscalls was reported. http://www.linux-mips.org/archives/linux-mips/2004-10/msg00142.html It seems uClibc should be fixed also for newer gcc. Here is a patch.
