26f9b1d38b Fix instruction skipping on MacOS X in the fast path case. 2007-12-31 18:07:01 +00:00

b5ac365858 Add support for 64-bit MacOS X for PowerPC (untested beyond "it compiles"). 2007-12-31 06:59:39 +00:00

9fa1bbd972 According to kernel sources, that is XNU 344.49 (10.2.8), XNU 517.12.7 (10.3.9), 
XNU 792.21.3 (10.4.10) and XNU 1228 (10.5.0), exception handler code[1] always
contains the fault address nowadays. So make it the default fast path but keep
provisions to check that at run-time first.

This yields a nearly 4x improvement in SIGSEGV recovery but MacOS X is still
suboptimal wrt. Linux, so VOSF is still not possible with frameskip == 0.

XXX: the ppc kernel had bugs that caused DAR (put into code[1]) to be incorrectly
decoded. This would need a broader test audience or more careful audit of the
sources changes.

9000d4f54c Rewrite ExtFS support for MacOS X. This implementation uses xattrs (metadata) 
on Tiger+ to store FInfo and FXInfo. Otherwise, plain old .finfo/ helpers are
used. "Safe" flags and fields are always synchronized to/from MacOS X.

BTW, CFString leak was fixed at the same time.

2e95c43bf2 Remove the 33-bit addressing hack as it's overly complex for not much gain. 
Rather, use an address override prefix (0x67) though Intel Core optimization
reference guide says to avoid LCP prefixes. In practise, impact on performance
is measurably marginal on e.g. Speedometer tests.

1470a8af13 NQD dirty boxes, SDL backend. 
This reduces the number of Screen_fault_handler() calls by 80%. i.e. VOSF
is now viable on this turtle MacOS X. Besides, since there is no buffer
comparison, idle sleep can really be effective. SheepShaver in idle mode
on my PBG4 now goes below 8% of CPU resources instead of 70-80% with
bounding boxes based video refreshes.

Caveat: if your program doesn't use standard MacOS routines that call NQD,
then you can expect slower (visual) performance. However, I do think the
new default behavior (VOSF+NQD) is the most common.

3b07ba27e4 Introduce a new video refresh function that uses smaller bounding boxes. 
This does not improve graphics performance but helps CPU because it reduces
the number of bytes transfered to actual screen. I saw an improvement by up
to 26% in frameskip 4 800x600x16 but also a hit by 3% with frameskip 0.

The next step is to use NQD bounding boxes to help detecting dirty areas.

So far, this is the best I can do without VOSF working (MacOS X performance
bugs -- pitifully slow Mach syscalls)
