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.
