NT_INTERRUPT issues - Githubissues

Bearsoft749 commented 11 months ago

This code works in GCC 6.5 but does not work in GCC 13.1. I must use "m68k-amigaos-strip" to get it to be executable in GCC 13.1.

#include <stdio.h>
#include <unistd.h>
#include <proto/exec.h>
#include <exec/execbase.h>
#include <hardware/intbits.h>

struct Interrupt *vbint2;
int counter;
int quit;
int value=0;
int valueEnd=60;

void startInterrupt(void *interruptFuncton)
{
    vbint2=NULL;

    if (vbint2 = (struct Interrupt *)AllocMem(sizeof(struct Interrupt), MEMF_PUBLIC|MEMF_CLEAR))
    {
        vbint2->is_Node.ln_Type = NT_INTERRUPT;

        vbint2->is_Node.ln_Pri = -60;   //-60
        vbint2->is_Node.ln_Name = "VertB";
        vbint2->is_Data = (APTR)&counter;
        vbint2->is_Code = (void (*)())interruptFuncton;

        AddIntServer(INTB_VERTB, vbint2); 
    }
    else 
    {
        printf("Can't allocate memory for interrupt node\n");   
    }
}

void endInterrupt()
{
    quit=1;

     if (vbint2 != NULL)
     {
        RemIntServer(INTB_VERTB, vbint2);
        FreeMem(vbint2, sizeof(struct Interrupt));

//        printf("%ld vertical blanks occurred\nRemoving server\n", counter);
     }
}

int waitInterrupt()
{
    if (quit==2)
    {
        quit=0;
    }

    int tempQuit=quit;
    quit++;

    return tempQuit;
}

int interruptLoop()
{
    while(!waitInterrupt())
    {
        value++;

        if (value>=valueEnd)
        {
            value=valueEnd;
        }
    }
}

int main()
{
    startInterrupt((void*)interruptLoop);

    while(value<valueEnd)
    {
        sleep(3);
    }

    endInterrupt();

    printf("value %d\n", value);

    return 0;
}
