Subject: Fix a bug in PerformEXTRACT_VECTOR_ELTCombine. The code created an ADD SDNode
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=86694297ff146275d74a7312fef1d2f0c41d4b19;p=oota-llvm.git

Fix a bug in PerformEXTRACT_VECTOR_ELTCombine. The code created an ADD SDNode
with two different types, in cases where the index and the ptr had different
types.
