[avr-gcc-list] GCC Functions

[Patrick Lanphier]

It appears that when I start using functions the code stops working.  Why?

/*
*************************************************************************
avr-gcc -O0 -Wall -mmcu=at90s2313 -c demo2c.c -o demo1.o
avr-gcc -o demo1.elf demo1.o
avr-objcopy -O ihex demo1.elf demo1.hex
**************************************************************************
*/

#include <io2313.h>
#include <interrupt.h>

void led1(void);
int ledlight;

int main(void) {
  outp(0xff, DDRB);           // port B all outputs
  outp(0xff, PORTB);          // turn all leds off
  led1();
  for(;;){
    outp(ledlight, PORTB);        // turn led on
  }
}

void led1(void){
  ledlight = 0x0;
};
