Pahole and the dwarves
Unless I'm missing something, it seems like pahole `--btf_encode_detached` doesn't export all the global variables ```shell $ ../pahole_git/build/pglobal -v vmlinux-5.8.0-53-generic | sed '/^$/d' | wc -l 26843 $ ../pahole_git/build/pahole --btf_encode_detached...
According to man: https://github.com/acmel/dwarves/blob/49358dfe2aaae4e90b072332c3e324019826783f/man-pages/pahole.1#L286-L288 But in the HEAD of repo, there is no reference of `dwarf_offset` besides man-pages: ```bash $ ag dwarf_offset rpm/SPECS/dwarves.spec 389:- PAHOLE: Add a newline after the...

Throwing userspace programs with atomic types at pahole currently results in either odd results (struct fiels with zero length) or straight up segfaults (dereferencing a NULL tag). Add DW_TAG_atomic_type analogous...
This fixes the use of classes_as_structs and probably other options, when fprintf meets a pointer/reference type. Signed-off-by: Alibek Omarov
On distros with elfutils version < 0.170 (SLES 15 SP3 for example), dwarves fails to build with the following error: ``` dwarf_loader.c:2529:13: error: ‘DW_TAG_skeleton_unit’ undeclared (first use in this function);...
