2010-08-14LoopSimplify shouldn't split loop backedges that use indirectbr. PR7867.Dan Gohman

2010-07-16LoopSimplify does not update domfrontier correctly.Tobias Grosser
This fixes PR7649. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@108513 91177308-0d34-0410-b5e6-96231b3b80d8
2009-11-20Make Loop::getLoopLatch() work on loops which don't have preheaders, asDan Gohman
it may be used in contexts where preheader insertion may have failed due to an indirectbr. Make LoopSimplify's LoopSimplify::SeparateNestedLoop properly fail in the case that it would require splitting an indirectbr edge. These fix PR5502. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@89484 91177308-0d34-0410-b5e6-96231b3b80d8
2009-11-05The introduction of indirectbr meant the introduction ofDan Gohman
unsplittable critical edges, which means the introduction of loops which cannot be transformed to LoopSimplify form. Fix LoopSimplify to avoid transforming such loops into invalid code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@86176 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-24Make these tests more interesting by usingDan Gohman
-verify-dom-info and -verify-loop-info, which enable additional (expensive) consistency checks. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@85017 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-19Fix SplitBlockPredecessors' LoopInfo updating code to handle the caseDan Gohman
where a loop's header is being split and it has predecessors which are not contained by the most-nested loop which contains the loop. This fixes PR5235. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@84505 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-28Move the dominator verification code out of special code embedded withinDan Gohman
the PassManager code into a regular verifyAnalysis method. Also, reorganize loop verification. Make the LoopPass infrastructure call verifyLoop as needed instead of having LoopInfo::verifyAnalysis check every loop in the function after each looop pass. Add a new command-line argument, -verify-loop-info, to enable the expensive full checking. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@82952 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-11Change tests from "opt %s" to "opt < %s" so that opt doesn't see theDan Gohman
input filename so that opt doesn't print the input filename in the output so that grep lines in the tests don't unintentionally match strings in the input filename. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81537 91177308-0d34-0410-b5e6-96231b3b80d8

2009-09-08Change these tests to feed the assembly files to opt directly, insteadDan Gohman
of using llvm-as, now that opt supports this. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81226 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-27Teach LoopSimplify how to merge multiple loop exits into a single exit,Dan Gohman
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

2006-12-31For PR950:Reid Spencer
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
