87e6b7108f Adds an unsafe disabled flag elimination pass 
This is a very useful optimization, but may only become "safe" once we
recompile a full function.
 2020-03-06 07:55:45 +02:00
Ryan Houdek
ee53b70bfe Actually enable LLVM optimization passes in the LLVM JIT 
We were using whatever was the LLVM default before.

9e132e107a Adds alignment information to the mem loadstore IR ops 
Allows us to not always emit unaligned loadstore ops for these

Ryan Houdek
f697da77b6 Splits up, documents, and extends the RCLE pass 
Splits this pass in to three parts.
First function is to remove StoreContext-LoadContext pairs that are
redundant. Removes the Load that has occured after a store-load pair.

Second function is to remove LoadContext instructions that are redundant
due to no other stores to that location

Third function is to remove StoreContext instructions that are redundant
due to no load happening between them (Relies on previous functions)

6dc7d2e679 Extends IR Validation to check exit to be correct 
Checks to ensure the last op in a block is EndBlock.
Checks to ensure the last instruction before that one is one of the ops
that exit correctly. So ExitFunction, Jump, CondJump, or Break.

a8d2cb4a9f Fixes LLVM JIT 
Doesn't yet work with multiblock

3a041c3b1c Fixes bug in block creation for any block containing RET. 
Would have a redundant StoreContext after the RET which broke IR
analysis

e1cecbcfe3 Changes to the new multiblock frontend decoder 
Simple linear scan forward of instruction decoding isn't viable to do.
We need to break up the decoding at the block boundaries.
Otherwise our decoding gets in to the weeds and decodes trash.

5db8de625a Adds a few new instructions to the X86Tables 
I managed to hit these when messing with Multiblock.
 2020-03-06 07:55:37 +02:00

704b8f9679 Disables Redundant Context Load Elimination pass. 
It's currently broken (Due to not 100% valid IR?)
 2020-03-06 07:55:37 +02:00
Ryan Houdek
b199ce70e9 Changes over IRValidation to the new format. 
We still can't pass this validation pass
 2020-03-06 07:55:37 +02:00
Ryan Houdek
b7c7a34cf6 Changes (aggressively) how branching is handled in the frontend. 
This changes over CondJump to have a defined True and False branch path.
Additionally needing to change over everything to handle this.
This now means that a false branch condition will no longer assume
fallthrough past this instruction.
Currently the x86-64 JIT generates an additional jmp instruction on
fallthrough that isn't optimized away.

This is working towards improvements in our IR branching model and
improving IRValidation in doing so.
This is working towards the model that IRBlocks can only have 0-2
successors.
Ret/Exit - 0 successors
Jump - 2 successors
CondJump - 2 successors

TBD:
Syscall/CPUID - Breaking block?
 2020-03-06 07:55:37 +02:00

fc8c6c80fb Makes sure in Frontend we say that Entry and ConditionalJump fallthroughs are JumpTargets 2020-03-06 07:55:37 +02:00

7da7880a41 Splits X86Table definitions in to multiple files 
Allows YouCompleteMe to handle these files and makes recompiling less of
a pain when one line is changed.

aabc6f6de2 Extends ConstProp pass a bit more. 
Still doesn't cover all the IROps but it hits quite a few more that I
could see.

160240dc23 Adds a few AVX instructions to the X86Tables 2020-03-06 07:55:35 +02:00

6890ae4e20 Adds an inblock time sampling routine to the x86-64 JIT 
Useful for a quick overview of the time spent in a function. It isn't
amazing for profiling since it effects the time in the function by
itself.
Only useful as a reference.

0a959475c5 Removes support for non-RA path on x86-64 JIT 
RA is now fully working, so this path is no longer necessary

668d392eb7 Adds support for spilling in the AArch64 JIT 2020-03-06 07:55:35 +02:00
Ryan Houdek
0eb86389de Cleans up RA spill slot calculation. 
RA spill slots now have live ranges so we can reuse the spill slot.
This can reduce spill stack usage significantly in code ranges with
large live ranges.
