Hi,
the patch below fixes PR 48613 which is an ICE with -O0
-findirect-inlining. Rather than adding "&& optimize" here and there,
at this place we can easily see whether there is something to do or
not by testing ipa_node_params_vector for NULL. And the
flag-triggering combinations can -and are - dealt elsewhere.
Bootstrapped and tested on trunk on x86_64-linux. OK for trunk and
subsequently for the 4.6 branch too?
Thanks,
Martin
