Detailed Description

template<typename ISelOp>
class llvm::ByteProvider< ISelOp >

Represents known origin of an individual byte in combine pattern.

The value of the byte is either constant zero, or comes from memory / some other productive instruction (e.g. arithmetic instructions). Bit manipulation instructions like shifts are not ByteProviders, rather are used to extract Bytes.
