¶llvm::Value* isBytewiseValue(
    llvm::Value* V,
    const llvm::DataLayout& DL)

Description

If the specified value can be set by repeating the same byte in memory, return the i8 value that it is represented with. This is true for all i8 values obviously, but is also true for i32 0, i32 -1, i16 0xF0F0, double 0.0 etc. If the value can't be handled with a repeated byte store (e.g. i16 0x1234), return null. If the value is entirely undef and padding, return undef.

Declared at: llvm/include/llvm/Analysis/ValueTracking.h:233

Parameters

llvm::Value* V

const llvm::DataLayout& DL
