CellSPU:
...
- First patch from Nehal Desai, a new contributor at Aerospace. Nehal's patch
fixes sign/zero/any-extending loads for integers and floating point. Example
code, compiled w/o debugging or optimization where he first noticed the bug:
int main(void) {
float a = 99.0;
printf("%d\n", a);
return 0;
}
Verified that this code actually works on a Cell SPU.
Changes by Scott Michel:
- Fix bug in the value type list constructed by SPUISD::LDRESULT to include
both the load result's result and chain, not just the chain alone.
- Simplify LowerLOAD and remove extraneous and unnecessary chains.
- Remove unused SPUISD pseudo instructions.

- Fix nonsensical logic in AssumeSymGE. When comparing 'sym >= constant' and the
constant is the maximum integer value, add the constraint that 'sym ==

- Improve AssumeSymGT. When comparing 'sym > constant' and constant is the
maximum integer value we know the path is infeasible.
- Add test case for this enhancement to AssumeSymGT.

Teach jump threading some more simple tricks:
...
1) have it fold "br undef", which does occur with
surprising frequency as jump threading iterates.
2) teach j-t to delete dead blocks. This removes the successor
edges, reducing the in-edges of other blocks, allowing
recursive simplification.
3) Fold things like:
br COND, BBX, BBY
BBX:
br COND, BBZ, BBW
which also happens because jump threading iterates.
