skrll 46ef072377 Fix for [on]{32,64} 
/usr/tests/lib/libc/sys/t_getcontext
/usr/tests/lib/libc/sys/t_swapcontext
/usr/tests/lib/libc/sys/t_ucontext
/usr/tests/lib/libpthread/t_swapcontext

All pass now.

Changes amount to

- saving GP from caller in context for n{32,64}
- performing (the equivalient of) PIC_PROLOGUE for swapcontext and
  __resumecontext
- Call setcontext via the PLT in __resumecontext

skrll 48bbbdf1d5 PIC_TAILCALL on n32/n64 would mess up GP, so just use SYSTRAP to call 
setcontext.

pooka 71859f7093 In rumprun mode on ARM, don't build syscall or signal code into libc.

 2015-08-20 16:13:40 +00:00
pooka 7db5875437 Don't include sigtramp or foocontext routines in rumprun mode. They won't 
work (since a rump kernel does not provide NetBSD _lwp syscalls nor
signals), but they cause unwanted symbols to be pulled in when the
resulting libc is linked.

dennis 75a496875b Replace the branch to __cerror() in powerpc64 syscall stubs 
with inline code which does what __cerror() was doing.  #ifdef
that code (i.e. all code) out of cerror.S; __cerror() is no more.
This seems to be necessary to fix the link of rescue/rescue, and
should have the pleasant side effect of making all other workarounds
done to keep the 'b __cerror' working unnecessary.

#include <sys/types.h>
    #include <stdio.h>

    int main(void) { ptrace(18, getpid(), NULL, 0xabcd); }

matt abb9139a12 The OpenRISC calling standard only passes 6 parameters by register. Any 
others are passed on the stack.  NetBSD syscalls use up to 8 parameters
so that could mean two left on the stack for the kernel to access.  It's
easier for the kernel if userland could fetch into registers beforehand.
So we generate sysassym.h which contains the number of arguments for each
syscall and then use that to determine how many arguments need to be fetched
from the stack.

nakayama 847b247653 Use save instruction to set up a local stack frame. 
This fixes a segmentation fault caused by bash 4.3 on sparc64
kernels with 32-bit userland, bash uses _setjmp/_longjmp heavyly
via sigsetjmp/siglongjmp since 4.3.

For 32-bit compat library which is compiled with -mcpu=ultrasparc
option (and define __sparc_v9__), use a similar code to 64-bit
library.
