No u havent. Sorry to say that u havent checked the code properly

No it will not be.
in $(UBOOT)/lib_arm/interrupts.c
#ifndef CONFIG_USE_IRQ ---> if not defined
void do_irq (struct pt_regs *pt_regs)
{
....
....
in $(UBOOT)/cpu/arm920t/interrupts.c
#ifdef CONFIG_USE_IRQ ---> if defined
#include <asm/proc-armv/ptrace.h>
void do_irq (struct pt_regs *pt_regs)
{
...
...
So both are mutual exclusive and finally only one will be compiled.

Its U-boot code style & GNU Toolchain compiler procedure in handling
preprocessor statements.
