attribs.c (decl_attributes): Imply noinline, noclone and no_icf attributes for noipa attribute.
* attribs.c (decl_attributes): Imply noinline, noclone and no_icf
attributes for noipa attribute. For naked attribute use
lookup_attribute first before lookup_attribute_spec.
* final.c (rest_of_handle_final): Disable IPA RA for functions with
noipa attribute.
* ipa-visibility.c (non_local_p): Fix comment typos. Return true
for functions with noipa attribute.
(cgraph_externally_visible_p): Return true for functions with noipa
attribute.
* cgraph.c (cgraph_node::get_availability): Return AVAIL_INTERPOSABLE
for functions with noipa attribute.
* doc/extend.texi: Document noipa function attribute.
* tree-ssa-structalias.c (refered_from_nonlocal_fn): Set *nonlocal_p
also for functions with noipa attribute.
(ipa_pta_execute): Set nonlocal_p also for nodes with noipa attribute.
c-family/
* c-attribs.c (c_common_attribute_table): Add noipa attribute.
(handle_noipa_attribute): New function.
testsuite/
* gcc.dg/attr-noipa.c: New test.
* gcc.dg/ipa/ipa-pta-18.c: New test.
