'isr' variant is to be called within interrupt safe context. Typically, traps/exception/context-switch need to be added this variant. On arm, -mgeneral-regs-only is passed to forbid the compiler to use enhanced CPU functions that are not saved within interrupt context (e.g., floating point units, vector units).
