f84ebf6bff sprintf->snprintf, fix some too short buffers 2014-09-14 00:14:11 +02:00
Unknown W. Brackets
52b6f1095e armjit: Fix rounding mode, allow non flush-to-zero. 
Default: force flush to zero (for RunFast mode.)  But now it's an ini
option so we can more easily compare armjit differences.

8daff0a25e armjit: Fix some downcount issues with rounding. 
When setting the rounding mode we need to be super careful about not
destroying flags or R0 if they are needed.

245a2a3be0 Don't zero out downcount in replacements. 
It doesn't write out js.downcountAmount in any of these cases, so zeroing
it is wrong.

d060a06fa6 Disable a bunch of function replacements. 
These are just for speed, let's turn them off.  Using a flag because:
 * I think there's still some issue with savestates, not sure.
 * We might swap this flag to a separate option.

24d8a34a0b Properly respect resolveReplacements. 
And use the same opcode reading func in armjit as x86jit.
Fixes Star Ocean on Android.

d09be5a4bc Update PC before going into a replacement func. 
This way we can report the PC properly on errors, and the replacement func
can even look at PC.

f489694515 Add the option to hook, rather than replace, funcs. 
This can be useful for debugging or developing translations/game hacks,
and also gives us options when dealing with GLES incompatibilities.

5a89c17cf0 armjit: Allow R1 in regalloc, use LR as temp. 
LR should be safe, although it may make stack traces not work within jit,
they don't really tend to work anyway.

438361d0bc Clean up code pointer naming for the jit. 
Now it properly identifies thunk code which is actually a decent percent
when fastmem is off at least.

1cb7965cb1 Jit feature preparation: Introduce "proxy blocks". 
When these are invalidated, the block they point to gets invalidated too.

Will be useful to implement various types of block merging and function inlining
without affecting correctness of cache clears etc.

Also, with this commit we can now fully inline replaced functions. fabsf() boils
down to 1-2 instructions and the block continues, for example.

2eab4aa1bf Play around with function replacement. Turned off by default of course. 2013-12-17 23:40:27 +01:00
Henrik Rydgard
2140892074 Initial preparations for ability to replace game functions with custom implementations. 
Also auto-saves hashmap additions and reapplies the hashmap on function
rename so that if you rename a function that exists in several copies
they will all be labelled.

Note that actual function replacement is not activated yet.

359110f010 x86/armjit: Add jump following (off by default.) 
Inlines function calls up to a certain extent.  Allows us to get
immediates all the way to a syscall, for example, usually.

Not sure if faster.

aacb31bc18 armjit: Copy over (disabled) immbranch optim. 
This does a little loop unrolling.  Costs a bit more cache space, but
avoids flushing regs for longer.

Not enabled.

So that it can optimize the value with existing imms.

Not actually optimizing yet.

15bc5a8db7 Add small ARM perf experiment. Did not help on ARMv7 so turned it off. 
xsacha might want to try it on ARMv6.

803148b8ca ARMv6: Fix offsets > 4096 for litpool. More aggressive check. 
Somehow Scooby Doo gets to offsets of ~4200 unless i drop the threshold down to ~3200. Not sure why the offset can jump by so much in one instruction.
Makes Scooby Doo playable now instead of showing a blue screen in the main game. Likely affects other games.
