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. * gcc.dg/ipa/ipa-sra-11.c: New test. From-SVN: r250607
