indirect function calls dont work on OSX i386

Created: 09/Feb/09 11:36 PM   Updated: 20/Feb/09 08:14 AM
Component/s: i386 target
Affects Version/s: None
Fix Version/s: None

Environment: OSX i386


 Description  « Hide
This may be a general PIC issue. The following code generates indirect function calls:

#include <stdlib.h>

int
main()
{
abort();
return 0;
}

like this:

L139:
        movl $L_abort$stub,%eax
        call *%eax

The linker complains that that this isn't valid PIC code. It can be changed to this:

        call L_abort$stub

or like:

movl L_abort$non_lazy_ptr,%eax
call *%eax

Need to check how this is handled on powerpc and update i386 target accordingly.

It's interesting that this piece of code fails, while pcc-tests/tests/c/codgen/types2.c works okay.

Added appropriate template for UCALL to match powerpc target.
