Practically, yes. But the process of manually reversing the trace path
is not easy because of the multiple code paths that may lead to a
function call.

What I'm looking for, is basically what GNU cflow calls a reverse
graph [1] but I'd like it to be able to give me code paths that span
multiple files (cflow can only process a single source file).

Unfortunately, Semantic or etags don't have the functionality I look
for.
