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

2004-06-19A utility to search the LLVM source tree for a grep pattern. This is aReid Spencer
replacement for getsrcs.sh which now generates too much text to put on a Linux command line. The approach taken with llvmgrep is to execute a find command and execute a grep on each file that matches the name pattern. The arguments to this script are the same as those of egrep. Note that the -H and -n options to egrep will always be passed so that you always get the file and line number of matches. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@14255 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
