of the function body in a loop allowing to split an operand into two.

comparison ops need implementation.

a memory reference.

(intel_e10, intel_e10_1): Combine, replace recursion with loop. Use
intel_brack_expr.
(intel_e11): Replace chain of if/else-if by switch, alloing fall-
through in certain cases. Use intel_brack_expr. Add new diagnostics.
Allow symbolic constants as register scale value.
(intel_get_token): Replace call to malloc and check of return value
