Detailed Description

template<unsigned NumBits>
class llvm::Bitset< NumBits >

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.

template<unsigned NumBits>

constexpr unsigned llvm::Bitset< NumBits >::getNumWords64 ( )

Return the number of 64-bit words needed to hold all bits.

◆ getWord64()

template<unsigned NumBits>

uint64_t llvm::Bitset< NumBits >::getWord64 ( unsigned I ) const

inlineconstexpr

Return the I-th 64-bit word of the bitset, from least significant to most.

All words other than the last contain exactly 64 stored bits. The last word (I == getNumWords64() - 1) may cover fewer than 64 stored bits when NumBits is not a multiple of 64; in that case the unused high bits are reported as 0.
