Stefanos Kornilios Mitsis Poiitidis a65bb87fa8 Merge pull request #183 from Sonicadvance1/fix_frontend_imm 
Fixes a bug in the frontend regarding constants
 2020-05-12 19:52:43 +03:00
Ryan Houdek 0b88984005 Fixes a bug in the frontend regarding constants 
Optimization passes found a bug in the frontend regarding constants.

Specifically in the case of instructions that have a 32bit constant that
are sign extended to 64bit was being incorrectly set to have a size of
32bits (the size of the constant).
So an optimization pass would rematerialize constants of the expected
size, thus ~0ULL would turn in to ~0U and generate invalid code.

Now watch the destination size and set the constant to that size, which
matches what its size will be.

Ryan Houdek e6e4634651 Ensures LLVM JIT doesn't crash if DebugInfo isn't provided 
IR doesn't have DebugInfo, all the other backends already handle this

Ryan Houdek 718b3e6b4c Refactors PassManager to ingest IREmitter class instead of OpDispatcher 
The Passmanager passes need very little or zero x86 knowledge to do
their work. They don't need the x86 OpDispatcher handling code at all.
Convert this entirely over to using the IREmitter class so it can
actually optimize IR code from the IRLoader frontend

Ryan Houdek dc87134af3 Switches the OpcodeDispatcher over to using the new IREmitter class 2020-05-08 19:08:14 -07:00
Ryan Houdek 1b720479c4 Adds a self contained IREmitter class 
This class does IR emitting and some basic handling of IR specific
tasks.

This is going to be used to split the x86 OpDispatcher from the IR
emission so the IR emitter can be passed around without caring about x86
dependencies.

Ryan Houdek 3528b30684 Fixes loading EXEC applications in to memory. 
If we are loading EXEC then we actually need to start loading in to the
lower 32bits of memory.
This lets the frontend code loader handle the memory base instead of
hiding it behind some core magic instead.

This lets us get EXEC programs working.
So now we support EXEC, DYN, and static applications
