void optimize_inline_calls (tree);
tree.h (DID_INLINE_FUNC): Remove macro. 2003-08-05 Steven Bosscher <steven@gcc.gnu.org> * tree.h (DID_INLINE_FUNC): Remove macro. (DECL_DECLARED_INLINE_P): Move from c-tree.h and cp/cp-tree.h, add tree check for FUNCTION_DECL. (DECL_ESTIMATED_INSNS): Move from c-common.h and java/java-tree.h. (struct tree_decl): Rename inlined_function_flag to declared_inline_flag. * c-common.h (c_lang_decl): Remove. (DECL_ESTIMATED_INSNS): Remove. * c-tree.h (struct lang_decl): Don't include c_lang_decl. (DECL_DECLARED_INLINE_P): Remove. * c-decl.c (grokdeclarator): Update comment. With -finline-functions, do not reset DECL_DECLARED_INLINE_P. Don't use DID_INLINE_FUNC. (finish_function): Make uninlinable a bool. Fixup call to tree_inlinable_function_p() and fix some code style issues. * cgraph.h (disgread_inline_limits): Fix spelling: `disregard'. * cgraph.c (dump_cgraph): Likewise. * cgraphunit.c (cgraph_decide_inlining): Likewise (cgraph_finalize_compilation_unit): Likewise. Also update call to tree_inlinable_function_p(). (cgraph_default_inline_p): Don't use DID_INLINE_FUNC. Instead look at DECL_DECLARED_INLINE and reverse logic. * print-tree.c (print_node): Likewise. * toplev.c (rest_of_handle_inlining): Don't use DID_INLINE_FUNC. * tree-inline.h (tree_inlinable_function_p): Make a bool. Update prototype. * tree-inline.c (inlinable_function_p): Split up in this function to check for basic inlining inhibiting conditions, and new limits_allow_inlining() function. Warn if inlining is impossible because the inline candidate calls alloca or uses sjlj exceptions. (limits_allow_inlining): this new function to check if the inlining limits are satisfied. Throttle from currfn_max_inline_insns, not from MAX_INLINE_INSNS_SINGLE. The latter only makes sense if MAX_INLINE_INSNS_AUTO and MAX_INLINE_INSNS_SINGLE are equal. Update prototypes. (tree_inlinable_function_p): Make a bool. Update call to inlinable_function_p (expand_call_inline): Use limits_allow_inlining() when not in unit-at-a-time mode to decide on inlining. Don't use DID_INLINE_FUNC, instead see if the function was declared `inline'. cp/ * cp-tree.h (struct lang_decl): Don't include c_lang_decl. (DECL_DECLARED_INLINE_P): Remove. * decl2.c (import_export_decl): Only look at DECL_DECLARED_INLINE_P if decl is a FUNCTION_DECL. This never made sense, but now it is required to avoid a tree check failure. * decl.c (grokfndecl): Don't touch DID_INLINE_FUNC. * optimize.c (maybe_clone_body): Likewise. java/ * java-tree.h (DECL_ESTIMATED_INSNS): Remove.
