OPTION SWITCH
OPTION SWITCH:[ C | PASCAL | TABLE | NOTABLE | NOREGS | REGAX ]
The switch comes in two main types: a structured switch (Pascal) or an unstructured switch (C). The default type is unstructured.
The TABLE and NOTABLE options control the jump-table creation in the switch. The default setting is NOTABLE.
The NOREGS and REGAX options control the usage of registers in jump-table creation in the switch. R10 and R11 is used in 64-bit else [E]AX. The default setting is NOREGS for ASMC and REGAX for ASMC64.
