I had not.. although xserver and weston are already using libunwind. I'm not sure about portability of libunwind to other libc implementations (but I guess it is at least not worse than using a glibc specific API). I suppose we could always add a fallback to backtrace(). > Also is the output format the same as before, or at least compatible with > gallium/tools/addr2line.sh? quite possibly not.. I chose to align to the format that xserver and weston was already using. Otoh, not sure if you would need to use addr2line.sh since it already decodes things to human readable fxn/file names.
