When trying to rematerialize a value before an instruction that has an early-clobber redefine of the virtual register, make sure to look up the correct value number. Early-clobber defs are moved one slot back, so getBaseIndex is needed to find the used value number. Bugpoint was unable to reduce the test case for this, see PR10388. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@135378 91177308-0d34-0410-b5e6-96231b3b80d8
