class AllocaSliceRewriter

Declaration

class AllocaSliceRewriter : public InstVisitor { /* full declaration omitted */ };

Description

Visitor to rewrite instructions using p particular slice of an alloca to use a new alloca. Also implements the rewriting to vector-based accesses when the partition passes the isVectorPromotionViable predicate. Most of the rewriting logic lives here.
