--- Comment #4 from Jan Hubicka <hubicka at gcc dot gnu.org> 2010-10-26 16:40:33 UTC --- Author: hubicka Date: Tue Oct 26 16:40:16 2010 New Revision: 165972 URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=165972 Log: PR middle-end/45736 * cgraph.c (cgraph_set_readonly_flag): Rename to... (cgraph_set_const_flags) ... this one; get also looping argument; clear constructor/destructor flags. (cgraph_set_pure_flag): Likewise. (cgraph_set_looping_const_or_pure_flag): Remove. (cgraph_can_remove_if_no_direct_calls_and_refs): Do not try to optimize away static ctors/dtors; it does not work on inline clones; external functions can always be rmeoved. (cgraph_will_be_removed_from_program_if_no_direct_calls): Assert on inline clones; in LTO external functions always can go. (cgraph_used_from_object_file_p): Handle EXTERNAL functions correctly. (cgraph_mark_address_taken_node): Assert that we are not taking address of inline clone. (cgraph_can_remove_if_no_direct_calls_p): We always eventually remove external functions. * ipa-cp.c (ipcp_cloning_candidate_p): Do not clone functions with address taken. (ipcp_initialize_node_lattices): Only local functions can be handled without cloning. * cgraph.h (cgraph_set_readonly_flag, cgraph_set_looping_const_or_pure_flag): Remove. (cgraph_set_const_flag): Declare. (cgraph_set_pure_flag): Update. * ipa-pure-const (propagate_pure_const, local_pure_const): Update flags setting code. * ipa.c (cgraph_remove_unreachable_nodes): Fix formating; do not look at inline clones; fix handling of external definitions. (cgraph_postorder): Do not look at inline clones in the first pass. (function_and_variable_visibility): Drop constructors/destructor flags at pure and const functions. * tree-profile.c (tree_profiling): Update. * ipa-inline.c (cgraph_clone_inlined_nodes): Always clone functions with address taken; external functions do not account to whole program size. (cgraph_decide_inlining): Likewise; do not try to inline functions already inlined. * testsuite/gcc.dg/lto/pr45736_0.c: New function.
