------- Comment #2 from rguenth at gcc dot gnu dot org 2007-02-21 12:33 ------- This is not a bug with inlining but at most with the cost function(s). Use -fdump-ipa-inline to follow the reasoning:
Deciding on inlining. Starting with 10 insns. Inlining always_inline functions: Deciding on smaller functions: Deciding on functions called once: Inlined 2 calls, eliminated 1 functions, 10 insns turned to 10 insns. so it believes code size is unchanged by inlining the function twice and removing the now unneeded out-of-line copy. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=30908
