2004-09-19Remove a whole bunch of horrible hacky code that was used to promote allocasChris Lattner
whose addresses where used by trivial phi nodes and select instructions. This is now performed by the instcombine pass, which is more powerful, is much simpler, and is faster. This allows the deletion of a bunch of code, two FIXME's and two gotos. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@16406 91177308-0d34-0410-b5e6-96231b3b80d8

2004-09-01Changes For Bug 352Reid Spencer
Move include/Config and include/Support into include/llvm/Config, include/llvm/ADT and include/llvm/Support. From here on out, all LLVM public header files must be under include/llvm/. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@16137 91177308-0d34-0410-b5e6-96231b3b80d8
2004-08-13If we are extracting a block that has multiple successors that are the sameChris Lattner
block (common in a switch), make sure to remove extra edges in successor blocks. This fixes CodeExtractor/2004-08-12-BlockExtractPHI.ll and should be pulled into LLVM 1.3 (though the regression test need not be, as that would require pulling in the LoopExtract.cpp changes). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@15717 91177308-0d34-0410-b5e6-96231b3b80d8

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
