2009-02-23 23:20:35 +00:00

Inline

If a function is marked alwaysinline, it must be inlined (possibly for correctness). Do so even if the callee has dynamic alloca and the caller doesn't.

2008-12-03 06:41:50 +00:00

LoopIndexSplit

If branch conditions' one successor is dominating another non-latch successor then this loop's iteration space can not be restricted. In this example block bb5 is always executed.
