Yes, you are right. In other places where we process range checks we use PhaseIdealLoop::is_scaled_iv_plus_offset() which checks Op_AddI (and Op_SubI).
13-08-2014
Odd that it wasn't noticed before. The problem is with finding and widening dominating range checks. The widening machinery expects to see certain forms of range checks. In one of the case (index + offset < array_length) it assumes that if a node in place of the addition operator says true to is_Add() it is really an arithmetic Add. However is just means that a node is a subclass of AddNode and shares the same algebraic properties. What this code needs, however, is to check the opcode of the node. Suggested fix: diff --git a/src/share/vm/opto/ifnode.cpp b/src/share/vm/opto/ifnode.cpp --- a/src/share/vm/opto/ifnode.cpp +++ b/src/share/vm/opto/ifnode.cpp @@ -503,7 +503,7 @@ jint off = 0; if (l->is_top()) { return 0; - } else if (l->is_Add()) { + } else if (l->Opcode() == Op_AddI) { if ((off = l->in(1)->find_int_con(0)) != 0) { ind = l->in(2); } else if ((off = l->in(2)->find_int_con(0)) != 0) {

Actually, extension is not necessary, C2 directly passed the index to CmpU of the range check, and since the size of the array is always < 2^31 - 1 the negative value are not going to pass the range check anyway. However in this case the problem is that we eliminate the range check...

Ok, it is unextended -2. Normally (-Xint) the program exits with exception: Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: -2 at WordsSum.maxSum4(WordsSum.java:65) at WordsSum.main(WordsSum.java:14)
