[lldb-dev] Detect executable archs before CreateTarget

Actually this was pretty easy to do, so here is a patch with the new public API I propose:

I have tested it on my machine (MacOSX 10.8) with a couple of bundles and it works fine. Let me know what you think.

Cheers,

For now the only way to do somehow do that is to loop over all known archs and try to create the SBTarget. Depending on its success I mark the arch as valid or not. As you can guess this is very slow and stupid as lldb already has all the code needed to get this information without loading the full target.
