* Removing indvars tests that directly test canonical IVs and nothing else.Andrew Trick2011-09-121-15/+0

* Make LoopSimplify change conditional branches in loop exiting blocksDan Gohman2010-02-251-1/+1
| | | | | | | | | | | | which branch on undef to branch on a boolean constant for the edge exiting the loop. This helps ScalarEvolution compute trip counts for loops. Teach ScalarEvolution to recognize single-value PHIs, when safe, and ForgetSymbolicName to forget such single-value PHI nodes as apprpriate in ForgetSymbolicName. llvm-svn: 97126
* Teach ScalarEvolution how to compute a tripcount for a loop withDan Gohman2010-02-191-1/+1

* Use opt -S instead of piping bitcode output through llvm-dis.Dan Gohman2009-09-081-1/+1
