similar to: [PATCH] vfork() for parisc

Reimplement __common_syscall in assembler. The 32-bit ABI says that the fifth and sixth arguments to the function are passed on the stack, but our syscall ABI says they are passed in %arg4 and %arg5 like the 64-bit ABI. Also, tried to optimize the code slightly by making use of the cmpb delay slot to load the errno return of -1. Signed-off-by: Kyle McMartin <kyle@parisc-linux.org> diff

Hello all, I really want to support vfork() in klibc, mostly because uClinux *has* to use it. Unfortunately vfork() isn't allowed to use the stack *at all* across the system call -- including return address -- which means it needs an assembly wrapper on most architectures. I have tried implementing wrappers for most architectures, but I don't know parisc or s390/s390x well enough,

Hello Kyle, May be out of context but before I forget: > > + > > + /* store %r22 to errno... */ > > + ldil L%errno,%r1 > > + ldo R%errno(%r1),%r1 Could it not be 'load32 errno, %r1' (the assembly.h macro)?

Hi All, I has been trying to port the Samba package to uClinux. But our uClinux toolchain doesn't support the fork() call. I must replace the fork with vfork.If we use vfork, the smbd and nmbd can not work rightly. both samba-3.0.32 and samba-3.0.2a have the question. In samba/source/smbd/server.c, the function open_sockets_smbd(), creates a child process and a parent process. Both these

Hi klibc people, if someone has to say more on this, please do so.

The PA-RISC ELF ABI puts the function pointer to be registered with atexit in %r23. Use this instead of passing in NULL. While it's unlikely to be used, doing the right thing is good.

tag 334917 = patch thanks Hi, I?ve fixed the m68k syscall of klibc and made it able to use six-argument syscalls like mmap2. However, I could not yet fully test it (only mostly; opendir() specifically fails) due to: http://gcc.gnu.org/bugzilla/show_bug.cgi?id=47533 @m68k porters: Please have a look at the gcc bug as well. @klibc: Please apply the patch, it?s better than what we have, and

I have updated the klibc patchset based on feedback received. In particular, the patchset has been reorganized so as not to break git-bisect. Additionally, this updates the patch base to 2.6.17-git12 (d38b69689c349f35502b92e20dafb30c62d49d63) and klibc 1.4.8; the main difference on the klibc side is removal of obsolete code.
