...Right, and you can see samples of IRQ registration by looking at one of the drivers that implements one.

Take the UART, for example. It has an initialization routine, alt_avalon_uart_init, which registers an interrupt with the system. The IDE build process creates a file (alt_sys_init.c) which initializes all of your devices and registers all of their interrupts.

Don't trouble yourself looking for an interrupt vector table. There isn't one. If, however, you are using the HAL, all IRQ numbers are defined in system.h.
