- Avoid undefined behavior in negation in LSR. Patch by Ahmed Charles. · b46345d7
  Eli Friedman authored Oct 13, 2011
```
Someone more familiar with LSR should double-check that the extra cast is actually doing the right thing in the overflow cases; I'm not completely confident that's that case.

  Eli Friedman authored Oct 13, 2011
```
Enhance the memdep interface so that users can tell the difference between a dependency which cannot be calculated and a path reaching the entry point of the function. This patch introduces isNonFuncLocal, which replaces isUnknown in some cases.
