Macro definition: The following code defines a macro, add3, with four parameters:
1 *
2
3 * add3
4 *
5 * ADDRP = P1 + P2 + P3
6
7 add3 .macro P1, P2, P3, ADDRP
8
9 ADD ADDRP, P1, P2
10 ADD ADDRP, ADDRP, P3
11 .endm
Macro call: The following code calls the add3 macro with four arguments:
12
13 00000000 add3 R1, R2, R3, R0
Macro expansion: The following code shows the substitution of the macro definition for the macro call. The assembler substitutes R1, R2, R3, and R0 for the P1, P2, P3, and ADDRP parameters of add3.
