        PR target/81921
        * targhooks.c (default_target_can_inline_p): Properly
        use target_option_default_node when no DECL_FUNCTION_SPECIFIC_TARGET
        is present and always compare.
        * config/i386/i386.c (ix86_valid_target_attribute_tree): Do not
        imply -mfpmath=sse from TARGET_SSE_P.
        (ix86_can_inline_p): Properly use target_option_default_node when
        no DECL_FUNCTION_SPECIFIC_TARGET is present and always compare.

        * gcc.target/i386/pr81921.c: New testcase.
