Adds missing pragma in RA pass
 2020-11-18 11:11:55 +02:00
Ryan Houdek c122516077 Adds resizable frontend decoded buffer 
Allows us to save memory in the frontend decoder by starting out with a
small buffer until we hit larger code blocks.

Ryan Houdek a1dacf87ac Adds missing pragma in RA pass 2020-11-17 12:29:28 -08:00
Ryan Houdek d17530623b Ensures pass validation goes through LogManager 
Now that it supports large strings we can push these through here.
We really need to avoid touching stdout/stderr as an interpreter

Stefanos Kornilios Mitsis Poiitidis 8fc6f73571 IR: InvalidateFlags + --abi-local-flags 
- InvalidateFlags pseudo-op is a hint for the Dead Flags Elimination pass that flags are not needed past that point
- Adds a new option, --abi-local-flags, that invalidates the flags on CALLs or RETs. This might break code that doesn't follow the ABI rules.

Ryan Houdek 1cd833e516 Merge pull request #499 from FEX-Emu/skmp/muliblock-ra-livespans 
RA: Greedily extend live ranges when values are used out of defining block
 2020-11-16 18:10:51 -08:00
Stefanos Kornilios Mitsis Poiitidis 075f3edcfe RA: Greedily extend live ranges when values are used out of defining block 
This fixes bogus RA when live ranges aren't contiguous, at the cost of
excessively increased register pressure.

This doesn't fix multi-block spilling, which requires fully working
PHI nodes among other things. As a workaround these ranges are marked
as unspillable.

Stefanos Kornilios Mitsis Poiitidis 2dad4718d6 IR: Add DumpIR option, --dump-ir command line 
This dumps the IR before and after optimizations

--dump-ir can be

"no" -> Do not dump
"stderr" -> Dump to stderr
"stdout" -> Dump to stdout
"some/path" -> Dump to "some/path/$GuestRip-pre.ir" and "some/path/$GuestRip-post.ir"

Stefanos Kornilios Mitsis Poiitidis 5fa5e49c58 IR: Add DeadGPRStoreElimination 
This is based on the Flag Elimination pass, and is not optimal - but does eliminate quite a few dead stores.

Ryan Houdek 34625441cb Fixes FCOMPP and FUCOMPP 
These two instructions pop the x87 stack twice which we didn't support
Repurposes the dead pop template argument to be a "pop twice".
Everything else falls down the table flag information comparison
 2020-10-27 23:09:17 -07:00
Ryan Houdek d3d57d48a0 Fixes missing pop flag in x87 table 
FCOMP didn't have POP set so it wans't popping the stack.
FFREEP also didn't have it, but it was handled explicitly in the
dispatcher

Ryan Houdek 7f4836b982 Fixes 32bit x87 usage 
All of the ops that were relying on a 64bit memory offset were being
downgraded to 32bit.

Abuses the XMM_FLAGS option a bit to indicate that it shouldn't
downgrade the 64bit size flag. Which isn't an issue since all these
operations can't encode a register since modrm_r is used for table
decoding
