scottr 8c9bf4e881 Use the size field to distinguish between ADDX and ADDA. Fixes a problem
pointed out by Paul Goyette.

scottr 651280426e Fix a problem pointed out by Paul Goyette: print_reglist() forgets that
it had a range of registers to print if A7 is among them.

thorpej ec897ee047 Fix a problem reported by Michael Hitch. Basically, our libc relies on the
non-standard way of invoking sigreturn, specifically a side-effect that I
overlooked.  Thus, longjmp's return value was getting clobbered.

Sigh, so burn trap #3 just as sigreturn.

XXX We need an SVR4-style {get,set}context(2) to avoid wasting new
XXX trap vectors in the future.

thorpej c227be8efc Expect the syscall number to push to be in register d0. 1998-10-01 00:11:11 +00:00
thorpej fa582abe7f Move trap #1 and trap #2 handlers here. Trap #1 handler now places
the cpmpat_13_sigreturn13 syscall number into d0 before calling the
sigreturn stub.

thorpej db9f3cbe30 Use the new special syscall entry point, and specify SYS___sigreturn14.
Makes the sigcode grow by 4 bytes.

Note that we are no longer able to use the HP-UX breakpoint "sigcodetrap"
hack here, as a result.  This means that BSD programs can no longer be
debugged by HP-UX debuggers.  *Sniff*  Don't break my heart...

__M68K_SIGNAL_PRIVATE.

kleink 1fbd0b3749 GC the unused `physadr' type, which was not able to hold a complete physical
address on 2 architectures anyhow.  Also, move the definition of the `label_t'
type inside _KERNEL protection, since it is specific to the in-kernel
setjmp()/longjmp() implementations.

cgd 651b44e211 Rework the way kernel include files are installed. In the new method,
as with user-land programs, include files are installed by each directory
in the tree that has includes to install.  (This allows more flexibility
as to what gets installed, makes 'partial installs' easier, and gives us
more options as to which machines' includes get installed at any given
time.)  The old SYS_INCLUDES={symlinks,copies} behaviours are _both_
still supported, though at least one bug in the 'symlinks' case is
fixed by this change.  Include files can't be build before installation,
so directories that have includes as targets (e.g. dev/pci) have to move
those targets into a different Makefile.

is 7a0f63f982 Back out the defopt for M680?0. As pointed out to me, this breaks ports which
dont use the M680?0 the way Amiga, Atari, Mac68k, and X68k do. I must have
missed this in the past discussion about this project.

thorpej f766e521be In kcopy(), make sure we save and restore the old fault handler; kcopy()
is called from uiomove(), which may be in the code path of servicing
a non-fatal page fault caused by a copyin() or copyout().

Originally suggested by Steve Woodford.
