Ever bothered to skim through include/pic/pic16f84a.h and/or the
pic16f84a datasheet?
<code name="ports.c">
#include <pic14regs.h> // may also use pic16f84a.h directly
typedef unsigned char u8;
u8 foo(u8 val) {
TRISA = 0x01; // RA0 is input, RA1-RA4 are outputs
PORTA = val;
RA1 = 1;
RA2 = 0;
return (RA0):
}

sdcc -mpic14 -p16f84a -c ports.c
