* [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

* Prevent loop-unroll from making assumptions about undefined behavior.Andrew Trick2013-05-312-22/+62
| | | | | | | | | | | | | | Fixes rdar:14036816, PR16130. There is an opportunity to compute precise trip counts for 'or' expressions and multi-exit loops. rdar:14038809: Optimize trip count computation for multi-exit loops. To do this we need to record the fact that ExitLimit assumes NSW. When it does not we can safely assume that the loop trip count is the minimum ExitLimt across all subexpressions and loop exits. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@183060 91177308-0d34-0410-b5e6-96231b3b80d8

* Disable statistics on Release builds and move tests that depend on -stats.Jan Wen Voung2013-03-082-0/+4
| | | | | | | | | | | | | | | | | Summary: Statistics are still available in Release+Asserts (any +Asserts builds), and stats can also be turned on with LLVM_ENABLE_STATS. Move some of the FastISel stats that were moved under DEBUG() back out of DEBUG(), since stats are disabled across the board now. Many tests depend on grepping "-stats" output. Move those into a orig_dir/Stats/. so that they can be marked as unsupported when building without statistics.

* Add a new attribute, 'noduplicate'. If a function contains a noduplicate ↵James Molloy2012-12-201-0/+23
| | | | | | | | | | call, the call cannot be duplicated - Jump threading, loop unrolling, loop unswitching, and loop rotation are inhibited if they would duplicate the call. Similarly inlining of the function is inhibited, if that would duplicate the call (in particular inlining is still allowed when there is only one callsite and the function has internal linkage). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@170704 91177308-0d34-0410-b5e6-96231b3b80d8
* getSmallConstantTripMultiple should never return zero.Hal Finkel2012-10-241-0/+44
| | | | | | | | | When the trip count is -1, getSmallConstantTripMultiple could return zero, and this would cause runtime loop unrolling to assert. Instead of returning zero, one is now returned (consistent with the existing overflow cases). Fixes PR14167. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@166612 91177308-0d34-0410-b5e6-96231b3b80d8

* Add -unroll-runtime for unrolling loops with run-time trip counts.Andrew Trick2011-12-094-0/+214
| | | | | | | | | | | | | | Patch by Brendon Cahoon! This extends the existing LoopUnroll and LoopUnrollPass. Brendon measured no regressions in the llvm test suite with -unroll-runtime enabled. This implementation works by using the existing loop unrolling code to unroll the loop by a power-of-two (default 8). It generates an if-then-else sequence of code prior to the loop to execute the extra iterations before entering the unrolled loop. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@146245 91177308-0d34-0410-b5e6-96231b3b80d8
* Fix a corner case in updating LoopInfo after fully unrolling an outer loop.Andrew Trick2011-11-181-0/+41
| | | | | | | | | | | | The loop tree's inclusive block lists are painful and expensive to update. (I have no idea why they're inclusive). The design was supposed to handle this case but the implementation missed it and my unit tests weren't thorough enough.

* Allow loop unrolling to get known trip counts from ScalarEvolution.Andrew Trick2011-08-111-0/+172
| | | | | | | | | | | | | | SCEV unrolling can unroll loops with arbitrary induction variables. It is a prerequisite for -disable-iv-rewrite performance. It is also easily handles loops of arbitrary structure including multiple exits and is generally more robust. This is under a temporary option to avoid affecting default behavior for the next couple of weeks. It is needed so that I can checkin unit tests for updateUnloop. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@137384 91177308-0d34-0410-b5e6-96231b3b80d8

* Fix the LoopUnroller to handle nontrivial loops and partial unrolling.Andrew Trick2011-08-102-0/+162
| | | | | | | | | | | These are not individual bug fixes. I had to rewrite a good chunk of the unroller to make it sane. I think it was getting lucky on trivial completely unrolled loops with no early exits. I included some fairly simple unit tests for partial unrolling. I didn't do much stress testing, so it may not be perfect, but should be usable now. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@137190 91177308-0d34-0410-b5e6-96231b3b80d8
