23aedf1e63 More sensible approach to the sc problem that broke Beats 2023-09-11 16:07:21 +02:00

df2462b1d9 irjit: Implement ll/sc. 
These occur more than I expected in LittleBigPlanet while loading.

0f5859510e x86jit: Simplify memcheck handling. 
Now it's mostly the same as the other jits.

f44852bb18 Global: Cleanup virtual/override specifiers. 
Also missing virtual destructors, hidden non-overrides, etc.

bac36df453 x86jit: Refactor and fix jump in branch delay slot. 
This seems cleaner, instead of the duplication of lines for each branch
type.

cae0815095 jit: Avoid using mips identifier directly. 
Apparently this gets defined on mips systems.

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.

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.

09e307b097 arm64jit: Update rounding mode on thread switch. 
Since fcr31 is per-thread, we must update jit state when it changes.
This also fixes the rounding mode on load state and jit/interp switch.

0207739d76 Can't call functions through known-nil pointers, even if they don't touch local data - LLVM's optimizer might have done something stupid. 2017-11-30 01:07:03 +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).

e37777648e jit-ir: Restore emuhacks before saving state. 
Let's just ask jit to do this, not its block cache directly.

a5be0976bd Remove preprocessor hacks to choose JIT implementation. 
Opens up for having multiple JIT implementations available at runtime,
which could be use for experimenting with new JIT compiler types or for
unit testing one JIT on another architecture.

Very few of the newly virtual calls are on any sort of critical path so
hopefully there will not be a performance loss.

d014d420db Unify JitOptions across the backends. 
This is required to make ExtractIR not a member of the various backends.

81dec36da8 Use an accessor to read the compilerPC. 
In the IR it will be read from the block.

a897723e6a Separate out jit reading nearby instructions. 
This makes it easier to use an IR for these things, or remove them.

This is virtually always safe.

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

2f598e8f38 jit: Statically jump for fixed branches. 
This handles both loops (first step is known) and static branches (some
code uses them instead of jumps, and we disassemble that to "b".)

Not likely to be a big improvement, but might help if the branch predictor
was wrong.

This is as opposed to continuing, which would build a larger jit block.

928e2adfc9 jit: Avoid applying/restoring the rounding mode. 
If the game never sets it, we can skip around syscalls, interpreter,
replacements, etc.

8d0dca71fe jit: Rename the rounding mode funcs to clarify. 
They apply/restore the value, set/clear is confusing.

4459b8f483 jit: Actually jit vmtfc/vmfvc. 
Sicne we have them and they are easy.

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.
