On receiving IRQ exception in SVC mode, all the SVC mode registers are saved onto the stack very early on. The stack frame allocation code for IRQ entry during SVC mode (svc_entry) is hard to read as 4-less is allocated initially only to be allocated later implicity using the mov r3, [sp, #-4]!

There are two common approaches to breaking long lines at binary operators: breaking the line before the operator (putting the operator at the start of the next line), or breaking the line after the operator (putting the operator at the end of the previous line). CodingStyle doesn't define any
