I'm not entirely sure that's what we want it to say, but it does seem like a reasonable expectation for users to have. Beyond this issue, what is the compile speed impact of the earlier change to use possibly_inlined_p? It seems like it might be making us speculatively instantiate a lot more functions for potential inlining even at -O1, which I would expect to cause memory bloat and slower compilation. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=39242
