* UpdatePHINodes in BasicBlockUtils should not crash on duplicate predecessorsHal Finkel2013-10-041-0/+46
| | | | | | | | | | | UpdatePHINodes has an optimization to reuse an existing PHI node, where it first deletes all of its entries and then replaces them. Unfortunately, in the case where we had duplicate predecessors (which are allowed so long as the associated PHI entries have the same value), the loop removing the existing PHI entries from the to-be-reused PHI would assert (if that PHI was not the one which had the duplicates). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@192001 91177308-0d34-0410-b5e6-96231b3b80d8
* [tests] Cleanup initialization of test suffixes.Daniel Dunbar2013-08-161-1/+0
| | | | | | | | | | | | | | | | | - Instead of setting the suffixes in a bunch of places, just set one master list in the top-level config. We now only modify the suffix list in a few suites that have one particular unique suffix (.ml, .mc, .yaml, .td, .py). - Aside from removing the need for a bunch of lit.local.cfg files, this enables 4 tests that were inadvertently being skipped (one in Transforms/BranchFolding, a .s file each in DebugInfo/AArch64 and CodeGen/PowerPC, and one in CodeGen/SI which is now failing and has been XFAILED). - This commit also fixes a bunch of config files to use config.root instead of older copy-pasted code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@188513 91177308-0d34-0410-b5e6-96231b3b80d8

* Convert all tests using TCL-style quoting to use shell-style quoting.Chandler Carruth2012-07-023-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | 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 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@159525 91177308-0d34-0410-b5e6-96231b3b80d8

* Teach LoopSimplify how to merge multiple loop exits into a single exit,Dan Gohman2009-06-271-0/+45
| | | | | | | | | | | | | | | | | when one of them can be converted to a trivial icmp and conditional branch. This addresses what is essentially a phase ordering problem. SimplifyCFG knows how to do this transformation, but it doesn't do so if the primary block has any instructions in it other than an icmp and a branch. In the given testcase, the block contains other instructions, however they are loop-invariant and can be hoisted. SimplifyCFG doesn't have LoopInfo though, so it can't hoist them. And, it's important that the blocks be merged before LoopRotation, as it doesn't support multiple-exit loops. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@74396 91177308-0d34-0410-b5e6-96231b3b80d8
