tests: kernel: gen_isr_table: support ISR_TABLE_USE_INTERUPT_ID option
Browse files Browse the repository at this point in the history 
When CONFIG_ISR_TABLE_USE_INTERUPT_ID is enabled, the isr table is
reordered. I modified it to reference the IRQ number and the operation
when the option is enabled to work correctly.
The table reordering only applies to ISRs defined with IRQ_CONNECT or
IRQ_DIRECT_CONNECT and does not affect interrupts enabled in code with
irq_connect_dynamic.
