class FeatureBitset

Declaration

class FeatureBitset { /* full declaration omitted */ };

Description

Container class for subtarget features. This is a constexpr reimplementation of a subset of std::bitset. It would be nice to use std::bitset directly, but it doesn't support constant initialization.

Declared at: llvm/include/llvm/MC/SubtargetFeature.h:40
