Hi, everyone.

I'm a student interested in the project "DWARF2 call frame information" for Summer of Code 2011. I'd like to know which compiler I will work on to add DWARF2 support. This project is not tagged by "suggested". Will it be ok to choose it as the target?

hi Xingxing,

You should carefully reread the proposed idea. Especially in the "A debug kernel is not able to show stack traces with cross exceptions anymore. This is because we do not emit any dwarf2 call frame information for any assembler code, since gdb switched to the dwarf2 format" part.

And, of course, this work is very important for the community. So, IMO, it will be ok as the target :) Thank you.

-- Have fun! chd

Hi chd,

Thank you for your reply. I thought the dwarf2 call frame information was generated by the toolchain. That's why I care about the states of the compiler. I'm not quite understand the proposed idea. Could you show me more details of the project? I really appreciate your support.

Thank you. Xingxing Pan
