* Temporarily Revert "Add basic loop fusion pass."Eric Christopher2019-04-171-32/+0
| | | | | | | | As it's causing some bot failures (and per request from kbarton). This reverts commit r358543/ab70da07286e618016e78247e4a24fcb84077fda. llvm-svn: 358546
* [SCCP] Teach the pass how to handle `div` with overdefined operands.Davide Italiano2017-01-191-0/+32
This can prove that: extern int f; int g() { int x = 0; for (int i = 0; i < 365; ++i) { x /= f; } return x; } always returns zero. Thanks to Sanjoy for confirming this transformation actually made sense (bugs are mine). llvm-svn: 292531
