2012-09-08MIPS/user: Fix reset CPU state initializationMaciej W. Rozycki1-0/+49
This change updates the CPU reset sequence to use a common piece of code that figures out CPU state flags, fixing the problem with MIPS_HFLAG_COP1X not being set where applicable that causes floating-point MADD family instructions (and other instructions from the MIPS IV FP subset) to trap. As compute_hflags is now shared between op_helper.c and translate.c, the function is now moved to a common header. There are no changes to this function. The problem was seen with the 24Kf MIPS32r2 processor in user emulation. The new approach prevents system and user emulation from diverging -- all the hflags state is initialized in one place now.

2012-06-04Kill off cpu_state_reset()Andreas Färber1-0/+3
In commit 1bba0dc932e8826a7d030df3767daf0bc339f9a2 cpu_reset() was renamed to cpu_state_reset(), to allow introducing a new cpu_reset() that would operate on QOM objects. All callers have been updated except for one in target-mips, so drop all implementations except for the one in target-mips and move the declaration there until MIPSCPU reset can be fully QOM'ified.

2009-08-24cleanup cpu-exec.c, part 0/N: consolidate handle_cpu_signalNathan Froyd1-0/+1
handle_cpu_signal is very nearly copy-paste code for each target, with a few minor variations. This patch sets up appropriate defaults for a generic handle_cpu_signal and provides overrides for particular targets that did things differently. Fixing things like the persistent (XXX: use sigsetjmp) should now become somewhat easier. Previous comments on this patch suggest that the "activate soft MMU for this block" comments refer to defunct functionality. I have removed such blocks for the appropriate targets in this patch.
