* Revert "Temporarily Revert "Add basic loop fusion pass.""Eric Christopher2019-04-171-0/+132
| | | | | | | | The reversion apparently deleted the test/Transforms directory. Will be re-reverting again. llvm-svn: 358552
* Temporarily Revert "Add basic loop fusion pass."Eric Christopher2019-04-171-132/+0
| | | | | | | | As it's causing some bot failures (and per request from kbarton). This reverts commit r358543/ab70da07286e618016e78247e4a24fcb84077fda. llvm-svn: 358546
* [InstCombine] allow mask hoisting transform for vector typesSanjay Patel2017-07-311-4/+4

* [InstCombine] add tests for mask hoisting; NFCSanjay Patel2017-07-311-0/+77
| | | | | | The scalar transforms exist with no test coverage. The vector equivalents are missing. llvm-svn: 309612
* [InstCombine] consolidate tests for DeMorgan folds; NFCSanjay Patel2017-04-301-22/+0
| | | | | | I'm proposing to add tests and change behavior in D32665. llvm-svn: 301774
* [InstCombine] add tests to show potentially bogus application of DeMorgan (NFC)Sanjay Patel2017-04-281-0/+22

* [InstCombine] regenerate checksSanjay Patel2016-04-051-36/+33
| | | | | | | | | utils/update_test_checks.py was improved with: http://reviews.llvm.org/rL265414 to CHECK-NEXT the first line of the IR function. This ensures that nothing bad has happened before that. llvm-svn: 265417
* [InstCombine] use FileCheck for better checkingSanjay Patel2016-03-251-23/+42

* Convert all tests using TCL-style quoting to use shell-style quoting.Chandler Carruth2012-07-021-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | 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

* Use opt -S instead of piping bitcode output through llvm-dis.Dan Gohman2009-09-081-2/+2
