3322adbc22 IR Interpreter: Add some missing instruction metadata. May help part of #10897 2018-04-11 11:16:41 +02:00

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.

irjit: Optimize out more temps and lwl/lwr operations

f01e06aefd irjit: Improve multiple lwr in a row. 2018-01-07 21:06:02 -08:00
Unknown W. Brackets
fbeedd333b irjit: Swap moves when it may allow clobbering. 
Example:
addiu a0, a1, a2
mov s0, a0
addiu a0, a2, a3

By swapping the mov, we can eliminate it.

Only going one back because it's common and didn't want to track reads.

d27e428659 irjit: Convert lwr and friends to easier code. 
This makes it easier to write a (working) jit backend from IR, since these
ops are always annoying to get right.
 2018-01-07 21:06:00 -08:00
Unknown W. Brackets
b11f00cead irjit: Combine lwl/lwr and swl/swr, like before. 
Still want to inline the operation, because the backend shouldn't have to
redo it every time, and we want the temps cleaned up if possible.

c6d690e9b8 irjit: Handle Left/Right ops in passes. 2018-01-07 21:05:57 -08:00

6dda053365 irjit: Add dedicated ops for lwl/swl and friends. 
Temporarily removes optimizations.
 2018-01-07 21:05:57 -08:00

cd3f4881a5 irjit: Optimize out temp lhs copies. 
Common example:
li v0, 1
beq s2, v0, somewhere
li v0, 2

Which was copying s2 before.  This pattern generally doesn't happen in
MIPS code, though, so really only catches that (very common) case.

97674b80bd irjit: Skip preloading blocks with jump to 0. 
These will be changed before executing anyway.

cc8e9a93c3 irjit: For debug, return the best block at addr. 
Invalidation may result in multiple matching blocks, prefer any that is
currently valid.

463b2a90c7 irjit: Allow precompiling funcs at start. 
This can take a second, but cuts down on jitc spikes throughout runtime.
Note: bits of the game will still be recompiled as games change code.

This is basically the same operation as loading from cache, without the
cache yet.

ccd562d934 irjit: Add a safety check for block num overflow. 
In case a game is very frequently modifying some block.

0bfab27b46 irjit: Calculate bloat statistics. 
At least based on IR for now.  Can do something else later.

memset() was causing a crash on the std::map.

cffb2d61a7 irjit: Embed constant inside IRInst. 
This simplifies a bunch of code and improves compile performance by about
30%, at the cost of a bit more memory.

b11858d9a0 irjit: Properly account for delay slots in size. 
Otherwise we think blocks are 4 bytes too short, which can affect
invalidation.

3abcc4d6d8 irjit: Implement lwl/lwr/swl/swr. 
This is very similar to the arm64jit implementation.

Unknown W. Brackets
b37ba9e599 irjit: Add options for compile/optimize steps. 
This way the backend can set flags for the type of IR it wants.  It's
seems too complex to combine certain things like lwl/lwr in a pass.

they're likely or something.

3af78883c7 irjit: Speed up icache block invalidation. 
Turns out, in games using a ton of small memcpys, this was causing perf
issues.

8c2edd432b irjit: Allow continuing from mips break. 
Some games currently generate break instructions, and can be played
otherwise.  Should be fixed, but let's not hard crash.
