In this case it is portable, because the Zig compiler source tree includes an interpreter for the blob (WASM) in portable C.

It's not objectionable to have non-portable source code anyway. I think it's fine having architecture-specific assembly code, just as long as it's hand-written.

The problems arise when you're storing generated content in the source repository, because it becomes unclear how you're meant to understand and fix the generated content. In this case it seems like the way to fix it is by rerunning the compiler, but if running the compiler involves running this incorrect blob, it's not clear that running the compiler again will produce a correct blob.

I wonder if anyone is monitoring these commits in Zig to ensure that the blobs are actually generated genuinely, since if not it seems like an easy way for someone to inject a KTH (Ken Thompson Hack): https://github.com/ziglang/zig/commits/master/stage1/zig1.wa...
