Makefile.in (c-decl.o): Depend on tree-inline.h. * Makefile.in (c-decl.o): Depend on tree-inline.h. (c-lang.o): Likewise, as well as insn-config.h and integrate.h. * c-decl.c: Include tree-inline.h. (c_expand_body): Call optimize_inline_calls. Determine whether a function is inlinable upfront, and only clear DECL_SAVED_TREE, DECL_INITIAL and DECL_ARGUMENTS if it isn't. * c-lang.c: Include tree-inline.h, insn-config.h and integrate.h. (c_disregard_inline_limits): New function. (inline_forbidden_p, c_cannot_inline_tree_fn): Likewise. (c_post_options): Enable tree inlining if inlining is enabled. Don't inline trees when instrumenting functions. (c_init): Initialize lang_disregard_inline_limits and lang_cannot_inline_tree_fn. * tree-inline.c (initialize_inlined_parameters): Handle calls with fewer arguments than declared parameters, and fewer parameters than passed arguments. Don't assume value is a DECL. (declare_return_variable): Convert return value back to the original type, if it was promoted. (tree_inlinable_function_p): New function. (inlinable_function_p): Don't look at DECL_INLINE if we're inlining all functions. Make it work with a NULL id. Re-check DECL_UNINLINABLE after language-specific checks. (varargs_function_p): Move back to cp/tree.c. * tree-inline.h (tree_inlinable_function_p): Declare it. (varargs_function_p): Removed declaration. * integrate.h (function_attribute_inlinable_p): Declare it. * integrate.c (function_attribute_inlinable_p): Export it. (save_for_inline): Don't bother to prepare argvec when not inlining. * cse.c (check_for_label_ref): Don't check deleted labels. From-SVN: r46025
