  • cpu.c: Removed duplicate declaration for _ISR_Vector_table.
  • cpu_asm.S: Removed assembly language to vector ISR handler on MIPS ISA I. Now call mips_vector_isr_handlers() in libcpu or BSP.
  • rtems/score/cpu.h (CPU_INTERRUPT_NUMBER_OF_VECTORS): No longer a constant -- get the real value from libcpu.
