This struct was having addresses taken of fields within it, and then being returned. It is platform-specific whether this causes a move. It seems to be working on x86_64, but causes a segfault on aarch64. Box the struct so that it isn't moved after being initialized. Signed-off-by: David Brown <david.brown@linaro.org>
Since there are references to this struct passed to C code, put it into an Rc so that it won't move around when the data is moved. Signed-off-by: David Brown <david.brown@linaro.org>
The symbols injected here cause some kind of poor interaction with the linker on MacOS, which results in most of the code becoming hopelessly corrupt. For now, just disable these symbols on this target. Signed-off-by: David Brown <david.brown@linaro.org>
Many of these extern functions are missing the "C". It doesn't seem to matter on any of our targets, but this does make the code more correct, and might be a problem in the future. Signed-off-by: David Brown <david.brown@linaro.org>
Cargo prints a warning about conflicting resolvers being used. Fix this by explicitly setting the resolver in the project file. Signed-off-by: David Brown <david.brown@linaro.org>
Increase the size of the jmpbuf to accomodate other architectures. Unfortunately, the size of this is not available in the libc crate. Increase this so encompass any platforms we wish to support, including aarch64 on both Linux and MacOS. Increasing an array beyond 32 means there is no default offered, so implement this manually.

Several fixes to allow the simulator to run on MacOS (aarch64). Several of these are actual problems with taking addresses of stack variables, or values that are later moved.
There is also a problem with the LLVM linker and the way the FIH_LABEL labels are added, which results in large blocks of code being discarded, and resulting in nonsensical code flow. For now, disable these labels on Apple targets, but as Rust is moving to the LLVM linker on other targets, this is likely to be more important.
Fixes #1979.
