2004-07-15Fix PR404: Loop simplify is really slow on 252.eonChris Lattner
This eliminates an N*N*logN algorithm from the loop simplify pass, replacing it with a much simpler and faster alternative. In a debug build, this reduces gccas time on eon from 85s to 42s. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@14851 91177308-0d34-0410-b5e6-96231b3b80d8

2004-06-21*FINALLY* Fix a really nasty nondeterministic bug that has been haunting usChris Lattner
since May 1st. In this code, the pred iterator was being invalidated sometimes causing the wrong entries to be added to PHI nodes. The fix for this is to defererence and safe the *PI value before we hack on branch instructions, which changes use/def chains, which SOMETIMES invalidates the iterator. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@14278 91177308-0d34-0410-b5e6-96231b3b80d8

2004-06-20Add some DEBUG output to the simplifycfg routinesChris Lattner
Fix another non-deterministic behavior, this one should actually speed up the code though as it was doing silly things. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@14258 91177308-0d34-0410-b5e6-96231b3b80d8

2004-06-19Do not let the numbering of PHI nodes placed in the function depend onChris Lattner
non-deterministic things like the ordering of blocks in the dominance frontier of a BB. Unfortunately, I don't know of a better way to solve this problem than to explicitly sort the BB's in function-order before processing them. This is guaranteed to slow the pass down a bit, but is absolutely necessary to get usable diffs between two different tools executing the mem2reg or scalarrepl pass. Before this, bazillions of spurious diff failures occurred all over the place due to the different order of processing PHIs: - %tmp.111 = getelementptr %struct.Connector_struct* %upcon.0.0, uint 0, uint 0 + %tmp.111 = getelementptr %struct.Connector_struct* %upcon.0.1, uint 0, uint 0 Now, the diffs match. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@14244 91177308-0d34-0410-b5e6-96231b3b80d8
2004-06-19Do not sort by the address of LLVM ConstantInt* objects. This producesChris Lattner
nondeterministic results that depend on where these objects land in memory. Instead, sort by the value of the constant, which is stable. Before this patch, the -simplifycfg pass run from two different compilers could cause different code to be generated, though it was semantically the same: @@ -12258,8 +12258,8 @@ %s_addr.1 = phi sbyte* [ %s, %entry ], [ %inc.0, %no_exit ] ; <sbyte*> [#uses=5] %tmp.1 = load sbyte* %s_addr.1 ; <sbyte> [#uses=1] switch sbyte %tmp.1, label %no_exit [ - sbyte 0, label %loopexit sbyte 46, label %loopexit + sbyte 0, label %loopexit ] We need to stomp all of this stuff out. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@14243 91177308-0d34-0410-b5e6-96231b3b80d8

2004-06-14Quick hack to get this file compiling again on Mac OS X. The right thing to doBrian Gaeke

2004-05-19Move RemapInstruction() to ValueMapper, so that it can be shared withBrian Gaeke
CloneTrace, and because it is primarily an operation on ValueMaps. It is now a global (non-static) function which can be pulled in using ValueMapper.h. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13600 91177308-0d34-0410-b5e6-96231b3b80d8

instruction in them. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13490 91177308-0d34-0410-b5e6-96231b3b80d8
2004-05-12Implement splitting of PHI nodes, allowing block extraction of BB's that haveChris Lattner
PHI node entries from multiple outside-the-region blocks. This also fixes extraction of the entry block in a function. Yaay. This has successfully block extracted all (but one) block from the score_move function in obsequi (out of 33). Hrm, I wonder which block the bug is in. :) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13489 91177308-0d34-0410-b5e6-96231b3b80d8
2004-05-12* Pull some code out into the definedInRegion/definedInCaller methodsChris Lattner
* Add a stub for the severSplitPHINodes which will allow us to bbextract bb's with PHI nodes in them soon. * Remove unused arguments from findInputsOutputs * Dramatically simplify the code in findInputsOutputs. In particular, nothing really cares whether or not a PHI node is using something. * Move moveCodeToFunction to after emitCallAndSwitchStatement as that's the order they get called. * Fix a bug where we would code extract a region that included a call to vastart. Like 'alloca', calls to vastart must stay in the function that they are defined in. * Add some comments. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13482 91177308-0d34-0410-b5e6-96231b3b80d8
2004-05-12Generate substantially better code when there are a limited number of exitsChris Lattner
from the extracted region. If the return has 0 or 1 exit blocks, the new function returns void. If it has 2 exits, it returns bool, otherwise it returns a ushort as before. This allows us to use a conditional branch instruction when there are two exit blocks, as often happens during block extraction. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13481 91177308-0d34-0410-b5e6-96231b3b80d8
2004-05-12Two minor improvements:Chris Lattner
1. Get rid of the silly abort block. When doing bb extraction, we get one abort block for every block extracted, which is kinda annoying. 2. If the switch ends up having a single destination, turn it into an unconditional branch. I would like to add support for conditional branches, but to do this we will want to have the function return a bool instead of a ushort. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13478 91177308-0d34-0410-b5e6-96231b3b80d8
