Compile with Proc Macro about rust-gpu HOT 2 CLOSED

Not really. spirv-builder invokes cargo with rustc_codegen_spirv as the backend for rustc. rustc_codegen_spirv links directly to rustc internals, and these are very unstable, so this needs to be the exact same toolchain, not just a nightly.
So in theory spirv-builder itself could use an arbitrary toolchain, stable even, but rustc_codegen_spirv must be used with the same nightly it was compiled with.
Proc macros are more or less supposed to consume and produce tokens, though some do read from files or even compile source code.

Surely there would be some way to check what toolchain it needs, and then check if it installed, and if not install it, then compile with that toolchain. It might be janky, but I reckon it would be possible. I'll close for now, but I'll mess around with it and see if I can get a basic implementation working.
