-/* Parse operands using Intel syntax. This implements a recursive descent
- parser based on the BNF grammar published in Appendix B of the MASM 6.1
- Programmer's Guide.
-
- FIXME: We do not recognize the full operand grammar defined in the MASM
- documentation. In particular, all the structure/union and
- high-level macro operands are missing.
-
- Uppercase words are terminals, lower case words are non-terminals.
- Objects surrounded by double brackets '[[' ']]' are optional. Vertical
- bars '|' denote choices. Most grammar productions are implemented in
- functions called 'intel_<production>'.
-
- Initial production is 'expr'.
