--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
Err, __builtin_popcount has an integer argument so you call popcount on
(int)m. The reason must be different.
(insn 17 16 26 4 (parallel [
(set (reg:SI 88 [ <retval> ])
(popcount:SI (subreg:SI (reg/v:TI 89 [ m ]) 0)))
(clobber (reg:CC 17 flags))
]) "t.c":4 -1
(nil))
