> Inputmon does have the enormous, un-auditable dependency of LLVM and Clang
You mean build-time dependency? Not a run-time one.
If that bothers you, there's simpler/smaller compilers out there (TinyCC and the Portable C Compiler come to mind, but there's others). Or drop down to assembly?
Yes, build-time.
Coincidentally, I had Claude fix 18 bugs in PCC earlier this week actually. But PCC itself doesn't support the UEFI calling convention or PE32+ image format. Those can be provided by something much smaller and simpler than LLVM, of course, but I'm not there yet.
