From aaf088b9826c33159f138b56b56679490864913a Mon Sep 17 00:00:00 2001 From: Natanael Copa Date: Tue, 29 Apr 2014 16:17:30 +0200 Subject: exec: replace ffsl with ctzl See commit fbeadf50 (bitops: unify bitops_ffsl with the one in host-utils.h, call it bitops_ctzl) on why ctzl should be used instead of ffsl. This is also needed for musl libc which does not implement ffsl.
