Re: [tcf-dev] How to distinguish between two symbols with the same name
|
Right, I forgot you can use ::. "file.c"::x (and function::x) should work in TCF already, because "file.c" resolves to DWARF compilation unit and the rest is regular C++ syntax for qualified name.

Ok. I see that gdb proposes to solve that by prefixing the symbol with
"file.c::" or "function::".
Is this something that would make sense to add in the TCF expression
evaluator?
