           Summary: virtex: passing argument 2 of 'ppc_exc_set_handler'
                    from incompatible pointer type
           Product: RTEMS
           Version: HEAD
          Platform: All
        OS/Version: RTEMS
            Status: NEW
          Severity: normal
          Priority: P3
         Component: bsps
        AssignedTo: joel.sherrill at oarcorp.com
        ReportedBy: ralf.corsepius at rtems.org


The virtex BSP contains this:

libbsp/powerpc/virtex/irq/irq_init.c:int C_dispatch_irq_handler
(CPU_Interrupt_frame *frame, unsigned int excNum)
libbsp/powerpc/virtex/irq/irq_init.c: ppc_exc_set_handler(ASM_EXT_VECTOR,
C_dispatch_irq_handler);
libbsp/powerpc/virtex/irq/irq_init.c: ppc_exc_set_handler(ASM_BOOKE_DEC_VECTOR,
C_dispatch_irq_handler);

i.e. it tries to install
  int C_dispatch_irq_handler (CPU_Interrupt_frame *frame, unsigned int excNum)
via 
 ppc_exc_set_handler 
(from libcpu/powerpc/new-exceptions/bspsupport/vectors.h)
which expects
 int (*ppc_exc_handler_t)(BSP_Exception_frame *f, unsigned vector)
as second argument.

This manifests in gcc issuing these warnings:
./../../../../../../../c/src/lib/libbsp/powerpc/virtex/irq/irq_init.c:324:2:
warning: passing argument 2 of 'ppc_exc_set_handler' from incompatible pointer
type [enabled by default]
../../../../../../../../c/src/lib/libbsp/powerpc/virtex/irq/irq_init.c:325:2:
warning: passing argument 2 of 'ppc_exc_set_handler' from incompatible pointer
type [enabled by default]

No idea about how to fix this. Seems as if a change to the powerpc's exception
handling wasn't propagated to the virtex BSP.
