Hi,
this patch updates inlining functions called once into inlining functions
called multiple times when the overall unit size for inlining everywhere
shriks. This is now quite possible in the cases where inline predicates catch
some DCE as seen in the silly testcase attached. We already caught most of
instances of those as part of inlining small functions but in rarer cases where
the function is too large we mis the oppurtunity.
Bootstrapped/regtested x86_64-linux, will commit it shortly.
Honza
* gcc.dg/ipa/inline-6.c: New testcase.
* ipa-inline.c (want_inline_function_called_once_p): Rename to ...
(want_inline_function_to_all_callers_p): check also functions with
multiple callers.
(ipa_inline): Handle inlining for size into multiple callers.
