An example of incorrect error position:

Test:
    s_sendmsg sendmsg(MSG_GS_DONE, GS_OP_NOP, 0)

Result:
    _test.s:6:11: error: message operation does not support streams
    s_sendmsg sendmsg(MSG_GS_DONE, GS_OP_NOP, 0)
              ^

Test:
    s_setreg_b32  hwreg(3,0,33), s2

Result:
    _test.s:6:15: error: invalid bitfield width: only values from 1 to 32 are
