        * tree.h (CALL_CANNOT_INLINE_P): New macro to access static_flag
        for CALL_EXPRs.
        * tree-inline.c (initialize_inlined_parameters): Do not call
        lang_hooks.tree_inlining.convert_parm_for_inlining.
        * cgraphbuild.c (initialize_inline_failed): Set inline failed
        reason for mismatched types.
        * gimplify.c (gimplify_call_expr): Verify the call expression
        arguments match the called function type signature.  Otherwise
        mark the call expression to be not considered for inlining
        using CALL_CANNOT_INLINE_P flag.
        * ipa-inline.c (cgraph_mark_inline): Honor CALL_CANNOT_INLINE_P on the
        edges call expression.
        (cgraph_decide_inlining_of_small_function): Likewise.
        (cgraph_decide_inlining): Likewise.
        * c-objc-common.h (LANG_HOOKS_TREE_INLINING_CONVERT_PARM_FOR_INLINING):
        Remove define.
        * c-tree.h (c_convert_parm_for_inlining): Remove declaration.

        convert_parm_for_inlining member.
