2017-03-02Add support for x86-interrupt calling conventionPhilipp Oppermann-0/+9
Tracking issue: https://github.com/rust-lang/rust/issues/40180 This calling convention can be used for definining interrupt handlers on 32-bit and 64-bit x86 targets. The compiler then uses `iret` instead of `ret` for returning and ensures that all registers are restored to their original values. Usage: ``` extern "x86-interrupt" fn handler(stack_frame: &ExceptionStackFrame) {…} ``` for interrupts and exceptions without error code and ``` extern "x86-interrupt" fn page_fault_handler(stack_frame: &ExceptionStackFrame, error_code: u64) {…} ``` for exceptions that push an error code (e.g., page faults or general protection faults). The programmer must ensure that the correct version is used for each interrupt. For more details see the [LLVM PR][1] and the corresponding [proposal][2].
