* Revert "Temporarily Revert "Add basic loop fusion pass.""Eric Christopher2019-04-171-0/+34
| | | | | | | | The reversion apparently deleted the test/Transforms directory. Will be re-reverting again. llvm-svn: 358552
* Temporarily Revert "Add basic loop fusion pass."Eric Christopher2019-04-171-34/+0
| | | | | | | | As it's causing some bot failures (and per request from kbarton). This reverts commit r358543/ab70da07286e618016e78247e4a24fcb84077fda. llvm-svn: 358546
* [IndVars] Un-grepify test; NFCSanjoy Das2016-08-031-1/+3
| | | | | | | | Some of these tests need to be cleaned up further to make it obvious what they're testing, but as a first step remove all instances of "grep". llvm-svn: 277648
* Convert all tests using TCL-style quoting to use shell-style quoting.Chandler Carruth2012-07-021-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | This was done through the aid of a terrible Perl creation. I will not paste any of the horrors here. Suffice to say, it require multiple staged rounds of replacements, state carried between, and a few nested-construct-parsing hacks that I'm not proud of. It happens, by luck, to be able to deal with all the TCL-quoting patterns in evidence in the LLVM test suite. If anyone is maintaining large out-of-tree test trees, feel free to poke me and I'll send you the steps I used to convert things, as well as answer any painful questions etc. IRC works best for this type of thing I find. Once converted, switch the LLVM lit config to use ShTests the same as Clang. In addition to being able to delete large amounts of Python code from 'lit', this will also simplify the entire test suite and some of lit's architecture. Finally, the test suite runs 33% faster on Linux now. ;] For my 16-hardware-thread (2x 4-core xeon e5520): 36s -> 24s llvm-svn: 159525

* When forgetting SCEVs for loop PHIs, don't forget SCEVUnknown values.Dan Gohman2009-05-121-0/+32
These values aren't analyzable, so they don't care if more information about the loop trip count can be had. Also, SCEVUnknown is used for a PHI while the PHI itself is being analyzed, so it needs to be left in the Scalars map. This fixes a variety of subtle issues. llvm-svn: 71533
