It all looks to be working fine on my side. There is a compilation error in our libbpf CI when building the latest pahole from sources due to DW_FORM_implicit_const being undefined. I'm updating our VMs to use Ubuntu Focal 20.04, up from Bionic 18.04, and that should hopefully solve the issue due to newer versions of libdw. If you worry about breaking others, though, we might want to add #ifndef guards and re-define DW_FORM_implicit_const as 0x21 explicitly in pahole source code. But otherwise, all good from what I can see in my environment. Looking forward to 1.20 release! I'll let you know if, after updating to Ubuntu Focal, any new pahole issues crop up. > https://git.kernel.org/pub/scm/devel/pahole/pahole.git/log/?h=DW_AT_data_bit_offset > > ? > > The cset has the tests I performed and the references to the bugzilla > ticket and Daniel has tested as well for his XDR + gcc 11 problem. > > Thanks, > > - Arnaldo
