Ryan Houdek 26a3290b43 Fix a couple mistakes in the x86 JIT using movsx instead of movsxd 2020-03-06 07:55:34 +02:00
Ryan Houdek 570ff7b29b Supports FS/GS on CMPXCHG 2020-03-06 07:55:33 +02:00
Ryan Houdek 52b5ac9e19 Changes slightly how IR::IRHeader is represented 2020-03-06 07:55:33 +02:00
Ryan Houdek f27f9485f6 Changes IR::CondJump's condition to dump textually. 2020-03-06 07:55:33 +02:00
Ryan Houdek 7a43b3150b Fixes bug in frontend displacement calculation
When an instruction had a literal and also a SIB displacement then this
was causing it to be calculated incorrectly.

Ryan Houdek 58e019fbf1 Disabled AVX512 reporting in CPUID
We don't support it and it'll be something we won't want to support for
a long time.

Ryan Houdek 6d92146578 Flesh out X86Tables some more
Adds an EVEX table and throws some ops in to an unimplemented function.
This is necessary for multiblock in the future where it will see
unsupported instructions but not actually execute them.

Scott Mansell d32ebc0de0 Signal our lack of support for CET shadow stacks
Needed to support binaries linked with glibc 2.30 and later.

glibc doesn't actually check CPUID, as kernel support is needed.
Instead, it just calls ARCH_CET_STATUS and checks for an error.

Ryan Houdek 13a15d6f3e Fix RA pass to support spilling 2020-03-06 07:55:17 +02:00
Ryan Houdek db5467211c Fixes the AArch64 JIT
Moves it to the new IR iterating style.
Forgot to clear icache after generation.
Fixes overly aggressive struct packing causing a fault

Ryan Houdek c21f711417 Adds a JitSymbols interface
This allows linux perf to see execution inside of JIT functions.
This could be extended in the future to support something like vtune or
oprofile.

Ryan Houdek 4ccdd689ce Fixes a bug in the CBW/CWDE/CDQE instruction
Was running at the wrong size the entire time

Ryan Houdek 199cfd76d8 Refactor IR and other changes that are hard to split
I had to change how blocks are represented to make it easier to parse
This required a fairly substantial refactor that makes it so blocks are
represented differently and we can walk them sequentially.

This will make future analysis easier to deal with.
Had to rewrite the passes and core's parsing of the IR afterwards.

Moved RA in to a optimization pass to be shared between the JIT backends
This works because x86-64 and AArch64 RA can be identical.

Still doesn't support PHI nodes or spilling correctly, this is the first
step in the process of getting there.

Ryan Houdek 40cad15da9 Cleanup old IR emitter functions
Argumentless IR emitter functions were prone to generating invalid code.
Remove them from the python emitter and change the branch instructions
that were using them to a new version instead.
Adds NumUse tracking as well.
