attr-noinline.c: Avoid pure-const optimization.
* gcc.dg/attr-noinline.c: Avoid pure-const optimization. * gcc.dg/pr33826.c: Update dump files. * gcc.dg/ipa/ipa-3.c: Avoid pure-const optimization. * gcc.dg/ipa/ipa-5.c: Avoid pure-const optimization. Merge from pretty-ipa: 2009-03-27 Jan Hubicka <jh@suse.cz> * cgraph.c (dump_cgraph_node): Add replace output flag by process. * tree-pass.h (function_called_by_processed_nodes_p): Declare. * passes.c (function_called_by_processed_nodes_p): New. * ipa-pure-const.c (check_call): Fix handling of operands. (analyze_function): Dump debug output for skipped bodies. (local_pure_const): Use function_called_by_processed_nodes_p. * dwarf2out.c (reference_to_unused): Use output. * passes.c (do_per_function_toporder): Likewise. 2008-11-12 Jan Hubicka <jh@suse.cz> * tree-pass.h (pass_fixup_cfg, pass_local_pure_const): Declare. * ipa-pure-const.c (funct_state_d): Add can throw field; make state_set_in_source enum (check_decl): Ignore memory tags; do not set fake looping flags; dump diagnostics. (check_operand, check_tree, check_rhs_var, check_lhs_var, get_asm_expr_operands, scan_function_op, scan_function_stmt): Remove. (check_call, analyze_function): Rewrite. (check_stmt): New. (add_new_function): Update call of analyze_function. (generate_summary): Add call of analyze_function. (propagate): Propagate can_throw; handle state_set_in_source correctly. (local_pure_const): New function. (pass_local_pure_const): New pass. * ipa-inline.c (inline_transform): Set after_inlining. * tree-eh.c (stmt_can_throw_external): New. * tree-optimize.c (execute_fixup_cfg): Do not set after_inlining; work with aliasing built. * tree-flow.h (stmt_can_throw_external): New. * passes.c (init_optimization_passes): Schedule fixup_cfg pass early; and local pure/const pass in early and late optimization queue.
