Presumably the insn which doesn't match uses call with some mode other
than SI.  What mode does it use?  What generated that insn with some
other mode?

Actually, most targets don't use a mode with call, since a call can
often return multiple modes.  But then they don't use a mode for the
result of the call, either.  Look at what other targets do.

Also, as it happens, it's generally OK to ignore the warning from the
MD file generator.  It's just a warning.
