Hi,
I don't really have testcase for the HP nor AIX ICE, however I can reproduce
same ICE when I hack x86 to
not use ctors/dtors. This patch fixes it - the problem is that ipa-prop ignore
newly added functions
(the global ctor built) while ipa-inline not and ipa-inline does use ipa-prop
for its analysis.
Fixed by adding the corresponding hook to ipa-prop, regstested&bootstrapped
x86_64-linux with the
hack and comitted. Let me know if it fixes your problem or not.

* ipa-prop.c (function_insertion_hook_holder): New holder.
(ipa_add_new_function): New function.
(ipa_register_cgraph_hooks, ipa_unregister_cgraph_hooks):
Register/deregister
holder.
