Storage modes

These are the storage modes that the compiler recognizes in asm macros:

treg

Compiler-selected temporary register.

ureg

C register variable that the compiler has allocated in a machine register.

reg

treg or ureg.

con

Compile time constant.

mem

A mem operand matches any allowed machine addressing mode, including reg and con.

lab

Compiler-generated unique label. The identifier(s) that are specified as being of mode lab do not appear as formal parameters in the asm macro definition, unlike the preceding modes. Such identifiers must be unique.

error

Generate a compiler error. This mode exists to allow you to flag errors at compile time if no appropriate pattern exists for a set of actual arguments.
