* [tests] Cleanup initialization of test suffixes.Daniel Dunbar2013-08-16
| | | | | | | | | | | | | | | | | - 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 Carruth2012-07-02
| | | | | | | | | | | | | | | | | | | | | | | | 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
* Enable the new LoopInfo algorithm by default.Andrew Trick2012-06-26
| | | | | | | | | | | | | | | | | | | | | | | | The primary advantage is that loop optimizations will be applied in a stable order. This helps debugging and unit test creation. It is also a better overall implementation without pathologically bad performance on deep functions. On large functions (llvm-stress --size=200000 | opt -loops) Before: 0.1263s After: 0.0225s On deep functions (after tweaking llvm-stress, thanks Nadav): Before: 0.2281s After: 0.0227s See r158790 for more comments. The loop tree is now consistently generated in forward order, but loop passes are applied in reverse order over the program. If we have a loop optimization that prefers forward order, that can easily be achieved by adding a different type of LoopPassManager. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@159183 91177308-0d34-0410-b5e6-96231b3b80d8

* Generalize LCSSA to handle loops with exits with predecessors outsideDan Gohman2009-11-09

LCCSA no longer actually requires LoopSimplify form, but for now it must still have the dependency because the PassManager doesn't know how to schedule LoopSimplify otherwise. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@86569 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | | | | | | | | | Update the test suite to accommodate the change from signed integer types to signless integer types. The changes were of only a few kinds: 1. Make sure llvm-upgrade is run on the source which does the bulk of the changes automatically. 2. Change things like "grep 'int'" to "grep 'i32'" 3. In several tests bitcasting caused the same name to be reused in the same type plane. These had to be manually fixed. The fix was (generally) to leave the bitcast and provide the instruction with a new name. This should not affect the semantics of the test. In a few cases, the bitcasts were known to be superfluous and irrelevant to the test case so they were removed. 4. One test case uses a bytecode file which needed to be updated to the latest bytecode format. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@32789 91177308-0d34-0410-b5e6-96231b3b80d8
