Description Tom Zanussi 2012-10-30 14:29:32 UTC 
DWARF support is needed for things like accessing variables in 'perf probe'.  I created a perf-dwarf feature back in July:

http://git.yoctoproject.org/cgit/cgit.cgi/poky-contrib/log/?h=tzanussi/perf-dwarf

But it caused perf to segfault and I never got back to it.

I have a version that doesn't segfault, but doesn't find the debug info it needs.  Need to debug further.
