Re: [ooc-compiler] Compiler error

Hi Frank,

Sorry for the delay, but here is what I think...

/* The working version */
OOC_CHAR8 L__IsEmpty(struct L__Header *list, RT0__Struct list__tag) {
   register OOC_INT32 i0;

   i0 = (OOC_INT32)*(OOC_INT32*)(OOC_INT32)list;
   return (i0==0);
   ;
}

/* The not working version */
OOC_CHAR8 L__IsEmpty(const struct L__Header *list__ref) {
   register OOC_INT32 i0;
   OOC_ALLOCATE_VPAR(list,L__Header ,1)

   OOC_INITIALIZE_VPAR(list__ref,list,L__Header ,8)
   i0 = (OOC_INT32)*(OOC_INT32*)(OOC_INT32)list;
   return (i0==0);
   ;
}

The generated code for L__IsEmpty is almost identical. If you remove
the OOC_ALLOCATE_VPAR and OOC_INITIALIZE_VPAR and change the list
by casting it to a (struct L__Header*) it should work. I arrived at
this conclusion, because the list__tag in the working code is
not used at all.

So what we could do to pinpoint the problem (I think) is change in the
non working code the L__IsEmpty function as shown below and run the test
again. (I assume that the generated C code can be changed and compiled)
The C compiler might issue warnings, but should compile (If I made no
mistakes).

OOC_CHAR8 L__IsEmpty(const struct L__Header *list__ref) {
   register OOC_INT32 i0;
   /*OOC_ALLOCATE_VPAR(list,L__Header ,1)*/

   /*OOC_INITIALIZE_VPAR(list__ref,list,L__Header ,8)*/
	 struct L__Header *list = (struct L__Header *)list__ref;
   i0 = (OOC_INT32)*(OOC_INT32*)(OOC_INT32)list;
   return (i0==0);
   ;
}

What I suspect is that the initialization/copying done by the
OOC_INITIALIZE_VPAR, OOC_ALLOCATE_VPAR pair is not correct.
If the above code works, then the problem would be in those
OOC_* calls (they might be macros).

If you would not mind, could you please do this change and
test?

Kind Regards,
Riza
