2013-02-16bitops: Use non-bitops ctzlRichard Henderson
The use of ctz has already eliminated zero, and thus the difference in edge conditions between the two routines is irrelevant. Signed-off-by: Richard Henderson <rth@twiddle.net> Reviewed-by: Eric Blake <eblake@redhat.com> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2013-02-02bitops: unify bitops_ffsl with the one in host-utils.h, call it bitops_ctzlPaolo Bonzini
We had two copies of a ffs function for longs with subtly different semantics and, for the one in bitops.h, a confusing name: the result was off-by-one compared to the library function ffsl. Unify the functions into one, and solve the name problem by calling the 0-based functions "bitops_ctzl" and "bitops_ctol" respectively. This also fixes the build on platforms with ffsl, including Mac OS X and Windows.
