[llvm-dev] DebugInfo work contribution and update.

[Jini Susan George via llvm-dev]

Hi David,



Yes, we are interested in the gdb side of things too – as Sourabh said, we
have been following Ali’s patches. I think we will co-ordinate with Ali to
see what gdb support for DWARF5 we can add so that we don’t tread on each
other’s toes.



Thanks!

Jini.
