More bugfixes

Ok, that’s about a wrap for the ‘month of bugs’. Mostly minor stuff again, but I’d be interested in hearing about anything that’s still failing to start with the latest svn revisions. And now back to some of those video bits and pieces that I keep putting off… (well, that and continuing to hammer on the ARM test cases as time permits)

Changes

* SH4: Mask SR, FPSCR, and the MMU/General IO registers properly
* SH4: Remove a number of harmless warnings that have been cluttering up the output
* SH4: Initial real perf counter implementation, at least for 0×23 (SH4 clock count)
* AICA: Set a sensible default value on the 0×2808 register
* GDROM: Fix reading NRG images with multiple DAOX/DAOI sections
* IDE: Generate the DMA interrupt on end of DMA rather than end of read (duh…)
* PVR2: Adjust hclip appropriately when using the horizontal scaler
* PVR2: Fix DMA/SQ writes to the VRAM32 region
* GUI: Display the current disc title in the title bar
* GUI: Change mouse grab to only take effect while actually running, and a grabby controller is configured (ie the DC Mouse).

Small Bug Fixes

I’ve been taking some time to tidy up a few lingering issues with the emulation, mostly small fixes but it does tend to take some time to find the bugs. As part of this, I’ve also started putting together a test harness for the ARM processor, but it’s not quite working on the actual hardware yet (In other news, the G2 bus hates me with a rather astounding passion).

I’ll probably keep going through these for another couple of weeks at this stage - it would be nice to get through the remaining known black-screen/hang type of bugs before I get back to mangling the renderer.
Changes

* SH4: Fix 64-bit bugs that broke the OS X 64-bit builds
* SH4: Fix ASID usage in ITLB lookups
* SH4: Fix core-exit on a translation-cache flush when it occurs in a branch delay slot
* SH4: Add the 1Cxx..1Fxx mapping for the P4 region when accessed through the TLB
* SH4: Add version register 0xFF000030 (read-only).
* SH4: Add undocumented performance counters (just stubbed for now) . Removes the 0xFF100008 warnings, but breaks save-state compatibility.
* ARM: Fix STM {R15} offset (should be +12, was +
* ARM: Add missing half-word load/store instructions
* ARM: Add test harness work-in-progress
* Other: Cleanup all the -Wall compile-time warnings

Minor OS X update

I’ve uploaded a new OS X binary package that actually runs on 10.4 now. It also includes a fix for the Intel GMA950, and a new .dst document icon. In any case, you probably only want this if the previous package didn’t work for you.
