mir.bitop

This module contains a collection of bit-level operations.

Members

bt auto bt(Field p, size_t bitnum): Tests the bit.
bta auto bta(Field p, size_t bitnum, bool value): Tests and assign the bit.
btc auto btc(Field p, size_t bitnum): Tests and complements the bit.
btr auto btr(Field p, size_t bitnum): Tests and resets (sets to 0) the bit.
bts auto bts(Field p, size_t bitnum): Tests and sets the bit.
ctlz T ctlz(T src): The 'ctlz' family of intrinsic functions counts the number of leading zeros in a variable. Result is undefined if the argument is zero.
ctlzp T ctlzp(T src): The 'ctlzp' family of intrinsic functions counts the number of leading zeros in a variable. Result is properly defined if the argument is zero.
ctpop T ctpop(T src): The 'ctpop' family of intrinsics counts the number of bits set in a value.
cttz T cttz(T src): The 'cttz' family of intrinsic functions counts the number of trailing zeros. Result is undefined if the argument is zero.
cttzp T cttzp(T src): The 'cttz' family of intrinsic functions counts the number of trailing zeros. Result is properly defined if the argument is zero.
