- The call to fentry is unconditionally added to the beginning of function.

& the other instruction may not be in the entry block?

- Should the call use the same debug location of the previous instruction if present?

No - it'll probably get that location anyway, later on/at code generation time, but you shouldn't add it to the instruction itself if it doesn't have any reason to be related/at that location.
