* Add a proper if-conversion cost model.Jakob Stoklund Olesen2012-08-101-13/+77
| | | | | | | | | | | | | | Detect when there is not enough available ILP, so if-conversion can't speculate instructions for free.

* Add more trace query functions.Jakob Stoklund Olesen2012-08-102-0/+42
| | | | | | | | | | | Trace::getResourceLength() computes the number of cycles required to execute the trace when ignoring data dependencies. The number can be compared to the critical path to estimate the trace ILP.
