| 2022-08-28 | Auto merge of #92845 - Amanieu:std_personality, r=Mark-Simulacrum | bors | -10/+0 | |
| Move EH personality functions to std These were previously in the panic_unwind crate with dummy stubs in the panic_abort crate. However it turns out that this is insufficient: we still need a proper personality function even with -C panic=abort to handle the following cases: 1) `extern "C-unwind"` still needs to catch foreign exceptions with -C panic=abort to turn them into aborts. This requires landing pads and a personality function. 2) ARM EHABI uses the personality function when creating backtraces. The dummy personality function in panic_abort was causing backtrace generation to get stuck in a loop since the personality function is responsible for advancing the unwind state to the next frame. Fixes #41004 | ||||

| 2021-08-03 | rustc: Fill out remaining parts of C-unwind ABI | Alex Crichton | -7/+5 | |
| This commit intends to fill out some of the remaining pieces of the C-unwind ABI. This has a number of other changes with it though to move this design space forward a bit. Notably contained within here is: * On `panic=unwind`, the `extern "C"` ABI is now considered as "may unwind". This fixes a longstanding soundness issue where if you `panic!()` in an `extern "C"` function defined in Rust that's actually UB because the LLVM representation for the function has the `nounwind` attribute, but then you unwind. * Whether or not a function unwinds now mainly considers the ABI of the function instead of first checking the panic strategy. This fixes a miscompile of `extern "C-unwind"` with `panic=abort` because that ABI can still unwind. * The aborting stub for non-unwinding ABIs with `panic=unwind` has been reimplemented. Previously this was done as a small tweak during MIR generation, but this has been moved to a separate and dedicated MIR pass. This new pass will, for appropriate functions and function calls, insert a `cleanup` landing pad for any function call that may unwind within a function that is itself not allowed to unwind. Note that this subtly changes some behavior from before where previously on an unwind which was caught-to-abort it would run active destructors in the function, and now it simply immediately aborts the process. * The `#[unwind]` attribute has been removed and all users in tests and such are now using `C-unwind` and `#![feature(c_unwind)]`. I think this is largely the last piece of the RFC to implement. Unfortunately I believe this is still not stabilizable as-is because activating the feature gate changes the behavior of the existing `extern "C"` ABI in a way that has no replacement. My thinking for how to enable this is that we add support for the `C-unwind` ABI on stable Rust first, and then after it hits stable we change the behavior of the `C` ABI. That way anyone straddling stable/beta/nightly can switch to `C-unwind` safely. | ||||
