2021-04-03	Manually set dso_local when its valid to do so	Simonas Kazlauskas	-7/+10
	This should have no real effect in most cases, as e.g. `hidden` visibility already implies `dso_local` (or at least LLVM IR does not preserve the `dso_local` setting if the item is already `hidden`), but it should fix `-Crelocation-model=static` and improve codegen in executables. Note that this PR does not exhaustively port the logic in [clang]. Only the obviously correct portion and what is necessary to fix a regression from LLVM 12 that relates to `-Crelocation_model=static`. Fixes #83335 [clang]: https://github.com/llvm/llvm-project/blob/3001d080c813da20b329303bf8f45451480e5905/clang/lib/CodeGen/CodeGenModule.cpp#L945-L1039

2017-03-02	Add support for x86-interrupt calling convention	Philipp Oppermann	-0/+28
	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].
