Consider the following S9 function:
<c> string a = "batata"; int s9() -> 0 {
a!
} </c>
The Postfix code for the above function is as follows:
<asm>
RODATA ALIGN LABEL _L123 ;; automatic label STR "batata"
DATA ALIGN LABEL a ID _L123 ;; automatic label
TEXT ALIGN GLOBL _main, FUNC LABEL _main ENTER 0
ADDRV a ;; ADDRV = ADDR+LOAD EXTRN prints CALL prints TRASH 4
INT 0 POP LEAVE RET </asm>
To test the first example, the S9 compilation process is as follows:
s9 batata.s9 yasm -felf batata.asm ld -o batata batata.o -lrts
To test the second program directly, pf2asm can be used:
pf2asm batata.pf yasm -felf batata.asm ld -o batata batata.o -lrts
