        <pre>Most assembler constructs allow use of expressions, however in many cases there
is an unclear limitation: an expression must start with a number.

Examples:

    set x = 3
    s_getreg_b32 s2, hwreg(10 + x) // ok
    s_getreg_b32 s2, hwreg(x + 10) // error

Full list of parser functions which enforce this limitation:

  - parseHwreg
  - parseSendMsgOp
  - parseSWaitCntOps
  - parseSOppBrTarget
  - parseIntWithPrefix
  - parseOperandArrayWithPrefix
  - parseOModOperand
  - parseDfmtNfmt</pre>
