CVS commit: syssrc/sys/arch/arm
Module Name: syssrc
Committed By: bjh21
Date: Fri Oct 18 21:33:00 UTC 2002
Modified Files:
syssrc/sys/arch/arm/arm32: cpuswitch.S genassym.cf vm_machdep.c
syssrc/sys/arch/arm/include: pcb.h
syssrc/sys/arch/arm/include/arm32: frame.h
Log Message:
In cpu_switch(), stack more registers at the start of the function,
and hence save fewer into the PCB. This should give me enough free
registers in cpu_switch to tidy things up and support MULTIPROCESSOR
properly. While we're here, make the stacked registers into an
APCS stack frame, so that DDB backtraces through cpu_switch() will
work.
This also affects cpu_fork(), which has to fabricate a switchframe and
PCB for the new process.
