Detailed Description

This pass does various peephole improvements to mask modification operations. In particular, it converts mask XORs with "all true" to calls to __not() and replaces operations like and(not(a), b) to __and_not1(a, b) (and similarly if the second operand has not applied to it...)

llvm::Value * MaskOpsCleanupPass::lGetNotOperand ( llvm::Value *  v) const

Checks to see if the given value is the NOT of some other value. If so, it returns the operand of the NOT; otherwise returns NULL.
