Update compiletest_rs dependency
Hello. I am trying to [update some Clippy dependencies](https://github.com/rust-lang/rust/pull/88517) in the rust repo. To help keep the overall number of dependencies down, I was asked to submit a PR here to update `compiletest_rs` to from `0.6.0` to `0.7.0`. I ran CI on my fork and the update didn't seem to cause any problems.
Try out gitpod
At https://gitpod.io/#https://github.com/rust-lang/miri one can edit miri in the browser and run it and everything.
I'm experimenting with this here as a low-impact version of trying it out on the whole rustc repo. This .gitpod file should cause the user to land in a shell that can run ./miri test immediately without any additional prep
Add support for the `volatile_set_memory` intrinsic
Add support for the unstable `volatile_set_memory` intrinsic
(Runtime behaviour and soundness requirements for `volatile_set_memory` are identical to those of `write_bytes`, so supporting this intrinsic is trivial.)
Use `Lrc` instead of `Rc` in `MiriCompilerCalls::config()`
The `used_crate_source` query defines its return type as [`Lrc<CrateSource>`](1195bea5a7/compiler/rustc_middle/src/query/mod.rs (L1418)), which would be `Arc` when `parallel-compiler = true`.
I assume this fixesrust-lang/rust#87623. I didn't test that locally -- I'm not interested in `parallel-compiler = true` enough to be willing to recompile rustc with that configuration to test it, but I'm submitting this in case it might be useful for `parallel-compiler = true` users.
also ignore 'thread leaks' with -Zmiri-ignore-leaks
This is a step towards https://github.com/rust-lang/miri/issues/1371. The remaining hard part would be supporting checking for memory leaks when there are threads still running. For now we elegantly avoid this problem by using the same flag to control both of these checks. :)
Fix use of deprecated `check_no_isolation` in posix fs shims
Update posix fs shims to use new API `reject_in_isolation`, which
allows rejection with error code instead of always forcing abort.
Error code chosen for each op is the most appropriate one from the
list in corresponding syscall's manual.
Updated helper APIs to not use quotes (\`) around input name while
preparing the message. This allows callers to pass multi-word string
like -- "\`read\` from stdin".
