Product: new-bugs
Version: unspecified

OS/Version: Linux
Status: NEW
Severity: normal
Priority: P
Component: new bugs

This is a recent regression; it is the cause of the dragonegg 64 bit buildbot
failure.
Testcase:
define void @foo() {
entry:
%e = extractvalue { i64, i64 } undef, 1
ret void
}
To reproduce:
$ opt -ipsccp -disable-output XCoreISelLowering.ll
opt: llvm/lib/Transforms/Scalar/SCCP.cpp:379: {anonymous}::LatticeVal&
{anonymous}::SCCPSolver::getValueState(llvm::Value*): Assertion
`!V->getType()->isStructTy() && "Should use getStructValueState"' failed.
