count_leading_zeros n
returns the number of most-significant zero bits before the most significant set bit in n
. If n
is 0, the result is the number of bits in n
, that is 32.
Same as count_leading_zeros
except if the argument is zero, then the result is undefined. Emits more efficient code.
This is no longer needed when using an flambda-backend compiler, which translates count_leading_zeros
to LZCNT by default (amd64).
count_trailing_zeros n
returns the number of least-significant zero bits before the least significant set bit in n
. If n
is 0, the result is the number of bits in n
, that is 32.
Same as count_trailing_zeros
except if the argument is zero, then the result is undefined. Emits more efficient code.
This is no longer needed when using an flambda-backend compiler, which translates count_trailing_zeros
to TZCNT by default (amd64).
