90517ace59 irjit: Validate alignment in slow memory mode. 2022-08-21 13:24:10 -07:00

6715f41410 irjit: Add constructs for validing mem access.
Basically to allow slow/fast memory to work with IR, including for
alignment checks.

7b081a61c8 irjit: Correct another PurgeTemps case.
In this case:
  Mov A, B
  AndConst A, A, 1
  Load32 C, A, 0

Was still swapping the Load32 to B, not just the AndConst.

Fixes #15735.

5abf1362a2 irjit: Clarify PurgeTemps, guard a couple ops.
Although I think we skip simplify passes on breakpoints entirely, safer to
exclude these ops.

2154f747fc irjit: Simplify more arithmetic to Movs.
Later passes rely on things being Mov, so better to have them more often.

c2a1caa2a2 irjit: Prevent corruption on purge temps pass.
If a switch occurs and then something clobbers the dest of that switch, we
were wiping out the first of those three instructions incorrectly.

1b00da2f3a Common: Sign extend w/func not chained casts.
Should be clearer to read and easier to get right.

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.

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.

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.

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.

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.
