An option would be to use the output of rustc --print file-names --crate-name {name} --crate-type bin, but that might be a cyclic dependency if this function is used to find the path to the rustc executable. See for example https://github.com/bjorn3/rustc_codegen_cranelift/blob/0b37af8c6168f11221ba74115eb3c5725fd13c3c/build_system/rustc_info.rs#L46-L74

From what I see, this function is used with a lot of binaries instead of crates, so I don't think rustc --print file-names --crate-name {name} --crate-type bin can be used at all places where exe is currently being used.

Yeah, if the binary name contains a -, it won't work. Cargo uses ____ as crate name once and then replaces the ____ in the output with the binary name every time. That should work I think.

This feels a bit awkward regarding cyclic dependencies, doesn't it? Even if you fetch a stage from an external source, this stage will not reflect the last build, so this function will be out-of-sync with the source it builds. Not necessarily a big issue, but maybe requires a bit more investigation. Not sure it is worth blocking this change on it?

Ideally you should ask the rustc binary that actually does the compilation for the artifact of which you want the filename. I do agree that it isn't worth blocking this change on.
