/* The sigvec system call on MIPS Ultrix takes an additional
|
|
parameter, which is the address that is actually called when the
|
|
signal occurs.
|
|
|
|
When a signal occurs, we arrange for the kernel to call __handler.
|
|
That will save the frame and stack pointers into the context, and
|
|
then jump to this routine. See __handler.S.
|
|
|
|
This code is based on sysdeps/unix/bsd/sun4/sigtramp.c, but it's
|
|
different because since we get passed the user signal handler we
|
|
don't actually need a trampoline. */
