Hi, experts:

I have a question about IRQ statck pointer alignment.

In arch/arm/lib/interrupts.c :

In Interrupt_init(void) function:

     IRQ_STACK_START = gd->irq_sp - 4;

     IRQ_STACK_START_IN = gd->irq_sp + 8;

     FIQ_STACK_START = IRQ_STACK_START - CONFIG_STACKSIZE_IRQ;

 

It seems not do alignment operation for IRQ_STACK_START /
FIQ_STACK_START .

 

Best wishes,
