Lightweight Profiling Specification

We will need a list of intrinsic/function names, not just the CPU instruction/opcodes

Torinde commented 3 months ago

Are the LLVM and Microsoft headers sufficient?

mr-c commented 3 months ago

I don't see how this would be implemented on non-x86 systems

Torinde commented 3 months ago

OK, then it should be dropped (and Issue closed)?

Or you think it can (and makes sense to) be implemented for x86 systems that don't natively support it?
