--- Comment #11 from Jan Hubicka <hubicka at gcc dot gnu.org> 2011-01-08 20:08:26 UTC --- Does --param hot-bb-frequency-fraction=100000 work here? This is weird!-( I have done the following profiling and it shows that -flto prevents the inlining of __perdida_m_MOD_perdida, while -fno-inline-functions restores it. This contradicts what the manual says: -finline-functions Integrate all simple functions into their callers. The compiler heuristically decides which functions are simple enough to be worth integrating in this way. Disabling autoinlining of small function can allow other inlining (inlining functions called once or inlining for size), so this is not completely unexpected.
