Paolo Bonzini	e8bb12c350	meson: let Meson handle mixed-language linking of Rust and C objects With the bump to Meson 1.10.0, C objects can be passed to rust targets. This way, the Rust libstd will be added by rustc itself in its final linker invocation. Use that to eliminate the staticlib and allow dynamic linking with libstd (also introduced by Meson 1.9.0, but not for staticlib crates due to lack of support in rustc). The main() function is still provided by C, which is possible by declaring the main source file of the Rust executable (which is still created by scripts/rust/rust_root_crate.sh) as #![no_main].

Paolo Bonzini	f0768791b5	rust: move strict lints handling to meson.build Simplify rustc_args.py, and align its code with what Meson's own Cargo.toml translator does in v1.10. Bump unknown_lints to "forbid", so that it will certainly override Cargo.toml's "allow" level.

Paolo Bonzini	2409089b87	rust: use native Meson support for clippy and rustdoc Meson has support for invoking clippy and rustdoc on all crates (1.7.0 for clippy, 1.8.0 for rustdoc). Use it instead of the homegrown version; this requires disabling the multiple_crate_versions lint (the only one that was enabled from the "cargo" group)---which was not particularly useful anyway because all dependencies are converted by hand into Meson subprojects. rustfmt is still not supported.

Paolo Bonzini	1d03e9771e	rust: add --check-cfg test to rustc arguments rustc will check that every reachable #[cfg] matches a list of the expected config names and values. Recent versions of rustc are also complaining about #[cfg(test)], even if it is basically a standard part of the language. So, always allow it.

Paolo Bonzini	de98c17593	rust: build: move strict lints handling to rustc_args.py Make Cargo use unknown_lints = "allow" as well. This is more future proof as we might add new lints to rust/Cargo.toml that are not supported by older versions of rustc or clippy. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>	1 year ago
Paolo Bonzini	90868c3dce	rust: cargo: store desired warning levels in workspace Cargo.toml An extra benefit of workspaces is that they allow to place lint level settings in a single Cargo.toml; the settings are then inherited by packages in the workspace. Correspondingly, teach rustc_args.py to get the unexpected_cfgs configuration from the workspace Cargo.toml. Note that it is still possible to allow or deny warnings per crate or module, via the #![] attribute syntax. The rust/qemu-api/src/bindings.rs file is an example.

Paolo Bonzini	97ed1e9c8e	rust: build: generate lint flags from Cargo.toml Cargo.toml makes it possible to describe the desired lint level settings in a nice format. We can extend this to Meson-built crates, by teaching rustc_args.py to fetch lint and --check-cfg arguments from Cargo.toml. --check-cfg arguments come from the unexpected_cfgs lint as well as crate features Start with qemu-api, since it already has a [lints.rust] table and an invocation of rustc_args.py.

Paolo Bonzini	1de82059aa	rust: build: restrict --cfg generation to only required symbols Parse the Cargo.toml file, looking for the unexpected_cfgs configuration.

Manos Pitsidianakis	ca5aa28e24	Revert "rust: add PL011 device model" Patch was applied with invalid authorship by accident, which confuses git tooling that look at git blame for contributors etc. Patch will be re-applied with correct authorship right after this commit.
