<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>
