struct DecIntegerState

Declaration

template <typename base_ty = uint32_t>
struct DecIntegerState { /* full declaration omitted */ };

Description

Specialization of the integer state for a decreasing value, hence 0 is the best state and ~0u the worst.

Declared at: llvm/include/llvm/Transforms/IPO/Attributor.h:2495

Templates

base_ty = uint32_t
