The documentation for GCC states that if the interrupt attribute is used, the iret instruction will be used instead of ret on x86 and x86-64 architectures. It also says, "Since GCC doesn’t preserve SSE, MMX nor x87 states, the GCC option -mgeneral-regs-only should be used to compile interrupt and exception handlers."
