[tcf-dev] Support for additional file format

[Didier Brachet <didier.brachet@xxxxxxxxxxxxx>]

Hi All,

We would need a TCF agent that supports several file formats. In our 
case, we would like to build an agent running on Windows that would 
support both ELF and PE (Portable Executable) file formats for the same 
debug session (ideally we would like to be able to mix PE & ELF for the 
same context or at least to be able to have a different file format for 
each context).

There is currently some code in the TCF agent to support PE using the 
Microsoft Debug Help Library for Windows native debugging support; 
however it is not possible to use this support with different TCF 
context interface (JTAG for example) without duplication some code and 
it is not possible to have support for both PE & ELF in the same agent.

We would like to update the TCF agent code (symbols & line numbers 
services as far as I know) to support multiple file formats by adding a 
multiplexer on top of symbols and line number services. I suspect there 
are additional changes that will be required to handle transitions 
between ELF & PE format in the same stack frame if we want to support this.

Does this make sense, do you foresee any issue?

Thanks,
Didier
