2009-09-26mips: do not save variables in "hi" or "lo" across system callsDaniel Jacobowitz
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.

2009-07-09syscall: unify part 2: NCS varietyMike Frysinger
Declare common NCS (non-constant syscall) variants and convert the existing ports over to this. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
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.

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.
2006-12-08Take Mike Frysinger's comments into account -- make certain that userEric Andersen
applications stop using _syscall#() and use syscall() instead. Cleanup internal handling of syscall includes to use the correct header file.

The mips64 N32/N64 ABI can pass much arguments via registers.

annoying warnings.
2005-03-14Make mips/mipsel syscalls no longer complain about the "use of memory inputEric Andersen
without lvalue in asm". Give the asm an lvalue so it can be happy.

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.

2002-07-26The __set_errno macro _must_ match that defined in include/bits/errno.h. WeEric Andersen
can't tack in the return -1 since then when people include errno.h, the return -1 mysteriously vanishes... Setting the __set_errno back and restoring the 'return -1;' calls to each _syscall[0-n] macro makes mips syscalls work again. -Erik

Prepare to kill the UNIFIED_SYSCALL option and instead have it be a per arch thing that is either enabled or not for that arch. -Erik
2002-02-04Be consistant about the ways in which asm/unistd.h mightEric Andersen
be included to avoid gratuitous conflicts... This is a hack till we have proper _syscall macros for all archs. -Erik
