b2798c7ada jit: Add more reasonable estimates for RX protect. 2022-11-20 10:55:35 -08:00
Unknown W. Brackets
3df6cb704f Global: Fix some type conversion warnings. 
Hidden by some warning disables.

4178f09e57 Build: More consistently avoid _M_ defines. 
We use PPSSPP_ARCH in several places already, this makes it more complete.

6b4356a060 Handle exec addr errors better - don't let IgnoreBadMemoryAccesses skip dispatcher exceptions. 
It would then just fall through into the compiler and die.

Should remove one of the "mystery" crashes from #14082.

c5e0b799d9 Remove category from _assert_msg_ functions. We don't filter these by category anyway. 
Fixes the inconsistency where we _assert_ didn't take a category but
_assert_msg_ did.

Unknown W. Brackets
ab809bd19e jit: Apply hasSetRounding at compile time. 
Otherwise, the block will be executed with the wrong rounding mode the
first time rounding is set.  This could be important if it was set for a
single operation.

This is only a problem the first time it's set.

cfa7c61651 More RIP removal. Also add some comments to make it easy to just search for "M(&" to find remaining offenders. 2017-07-07 11:33:06 +02:00

ff2b6b3fca Assorted cleanup, UWP memory map fixes. PSPFlower runs in both 32-bit and 64-bit. 2017-03-23 10:02:28 +01:00

b4740a2bca Fix bug where dispatcher would not check core state directly after Advance. Fixes #9398 properly (it was previously hidden somehow with extra backbuffer binds). 2017-03-14 12:32:20 +01:00

8c3552de74 cmake: Detect features at compile time 
Instead of relying on manually passed down flags from CMake,
we now have ppsspp_config.h file to create the platform defines for us.
This improves support for multiplatform builds (such as iOS).

b264657d56 Implement W^X-compatible path. Works on Windows and Android, hopefully iOS (untested). 
Disabled block linking in this mode, can re-enable with some more work later.

To enable W^X on other platforms than iOS, simply change PlatformIsWXExclusive.

a6294f3e2d Now the three backends actually do the same thing with rounding. Fixes a bug in the x86 backend, too. 2015-10-10 13:11:38 +02:00

7fee5abf9f x86/x64: Don't use a separate code block for pregenerated functions, just like on ARM 2015-10-08 22:15:28 +02:00

c41baab747 Pregenerate code to handle rounding mode switches. This time, for all three cores. 2015-10-08 19:58:37 +02:00

2743c5cacd x86jit: Shave off a couple bytes in asm. 2014-12-17 08:25:18 -08:00
Unknown W. Brackets
77777e372d x86jit: Use R15 when safe for the jit. 
This is virtually always safe.
 2014-12-17 08:09:59 -08:00
Unknown W. Brackets
9022b48069 x86jit: Skip reload of EAX in safe cases. 
Probably no real improvement in perf, but a bit cleaner and one less TODO.

05a8e2e35d Some work towards being able to build two JITs together 
This will be useful for testing/debugging, but not there yet.

8ad1ea4c84 Split JitCommon.h so that you can include it without getting the "NativeJit" definition 2014-12-13 21:13:28 +01:00
Unknown W. Brackets
928e2adfc9 jit: Avoid applying/restoring the rounding mode. 
If the game never sets it, we can skip around syscalls, interpreter,
replacements, etc.
 2014-10-12 12:51:45 -07:00
Unknown W. Brackets
8d0dca71fe jit: Rename the rounding mode funcs to clarify. 
They apply/restore the value, set/clear is confusing.

eab010a0c0 x86 JIT: Sacrifice a register for a pointer to the MIPS context. Shrinks emitted x86 code considerably. 
Nice in 64-bit, but might be a bit too much in 32-bit though... Needs testing.

5816685668 Handle the FS (flush-to-zero) bit in FCR31 for x86 JIT. 2014-09-04 01:50:24 +09:00
Unknown W. Brackets
925557ed47 x86jit: Maintain the rounding mode always. 
This should be less often than doing it per block that uses fpu, unless
the game doesn't use fpu much at all.
 2014-08-22 09:53:00 -07:00
Unknown W. Brackets
2347498667 x86jit: Use templates to avoid some void * casts. 
Makes it a bit cleaner and potentially safer.

2eab4aa1bf Play around with function replacement. Turned off by default of course. 2013-12-17 23:40:27 +01:00

598e06faa8 Make Home in the game browser available on linux/mac/etc too. 
Misc tweaks.

3fbb5d4388 Avoid using CALL() directly in case of far calls. 
This mainly matters for x64.

8438371941 Read memory in the jit dispatcher same as lw. 
Just for consistency.  One less op, maybe faster, probably same.

76481a300c Icache must be invalidated. Jit now starts to run, but there's no cube in cube.elf! 2013-01-08 23:52:11 +01:00

b3fd1ff34c Lots of various work on the ARM jit. It executes a couple of blocks now. 2013-01-08 13:49:52 +01:00
