Something as simple as:

        itc.i r18
        ;;
        ld8 r19=[r17]

Will generate
aa.S: Assembler messages:
aa.S:3: Warning: Use of 'ld8' violates RAW dependency 'DTC' (data)
aa.S:1: Warning: This is the location of the conflicting usage

Oddly enough, "as test.S" doesn't have warning message, but "as -x
test.S" does.  gcc is execve with "as -x" which triggers the warning
message.
