lib/libc/string: replace ffs/fls implementations with clang builtins 2023-07-03T20:18:27+00:00 Robert Clausecker fuz@FreeBSD.org 2023-06-23T16:22:54+00:00 ee8b0c436d7221c25e8be3c3fe1f9da78b9d5b16 Most architectures we support (except for riscv64) have instructions to compute these functions very quickly. Replace old code with the ffs and clz builtin functions, allowing clang to generate good code for all architectures. As a consequence, toss out arm and i386 ffs() implementations.
