//! Community-created implementations of [`gdbstub::arch::Arch`] for various //! architectures. //! //! _Note:_ If an architecture is missing from this crate, that does _not_ mean //! that it can't be used with `gdbstub`! So-long as there's support for the //! target architecture in GDB, it should be fairly straightforward to implement //! `Arch` manually. //! //! Please consider upstreaming any missing `Arch` implementations you happen to //! implement yourself! Aside from the altruistic motive of improving `gdbstub`, //! upstreaming your `Arch` implementation will ensure that it's kept up-to-date //! with any future breaking API changes. //! //! **Disclaimer:** These implementations are all community contributions, and //! while they are tested (by the PR's author) and code-reviewed, it's not //! particularly feasible to write detailed tests for each architecture! If you //! spot a bug in any of the implementations, please file an issue / open a PR! //! //! # What's with `RegIdImpl`? //! //! Supporting the `Target::read/write_register` API required introducing a new //! [`RegId`] trait + [`Arch::RegId`] associated type. `RegId` is used by //! `gdbstub` to translate raw GDB register ids (a protocol level arch-dependent //! `usize`) into human-readable enum variants. //! //! Unfortunately, this API was added after several contributors had already //! upstreamed their `Arch` implementations, and as a result, there are several //! built-in arch implementations which are missing proper `RegId` enums //! (tracked under [issue #29](https://github.com/daniel5151/gdbstub/issues/29)). //! //! As a stop-gap measure, affected `Arch` implementations have been modified to //! accept a `RegIdImpl` type parameter, which requires users to manually //! specify a `RegId` implementation. //! //! If you're not interested in implementing the `Target::read/write_register` //! methods and just want to get up-and-running with `gdbstub`, it's fine to //! set `RegIdImpl` to `()` and use the built-in stubbed `impl RegId for ()`. //! //! A better approach would be to implement (and hopefully upstream!) a proper //! `RegId` enum. While this will require doing a bit of digging through the GDB //! docs + [architecture XML definitions](https://github.com/bminor/binutils-gdb/tree/master/gdb/features/), //! it's not too tricky to get a working implementation up and running, and //! makes it possible to safely and efficiently implement the //! `Target::read/write_register` API. As an example, check out //! [`ArmCoreRegId`](arm::reg::id::ArmCoreRegId#impl-RegId). //! //! Whenever a `RegId` enum is upstreamed, the associated `Arch`'s `RegIdImpl` //! parameter will be defaulted to the newly added enum. This will simplify the //! API without requiring an explicit breaking API change. Once all `RegIdImpl` //! have a default implementation, only a single breaking API change will be //! required to remove `RegIdImpl` entirely (along with this documentation). #![cfg_attr(not(test), no_std)] #![deny(missing_docs)] pub mod aarch64; pub mod arm; pub mod mips; pub mod msp430; pub mod ppc; pub mod riscv; pub mod x86; // used as part of intra-doc link #[allow(unused_imports)] use gdbstub::arch::*;
