Upstream has since released version 1.15, with some miscellaneous bug
fixes. I've updated debian/master at
https://salsa.debian.org/tytso/dwarves.git
I've also updated the debian/changelog to have a describe the new
features since 1.12:
dwarves-dfsg (1.15-1) unstable; urgency=medium
* New upstream release (changes since 1.12):
- Add support for BTF encoding which is a much more compact way
of encoding C type information. It is derived from CTF (Compact
C-Type format) and is designed for use with eBPF.
- Add initial support for the DWARF DW_TAG_partial_unit
- Improve support for pretty-printing unions
- Teach pahole to show where a struct was used, via the -I option
- Use the running kernel by default when no file name is passed
- Improve man pages
- Support new BTF deduplication algorithm found the Linux kernel's
libbpf library, which allows type information for the kernel to
be stored in roughly 1% of the space.
- Add a new utility, btfdiff, which compares the pretty-printed
type information between two kernel images.
- Teach pahole to use the BTF information to pretty print structures
using the BTF information using "pahole -F btf", which is much faster
than using the Dwarf information.
- Infer the __packed__ attribute for structures without alignment holes
and which violate the natural types' alignment requirements.
- Support DWARF5's DW_AT_alignment tag
- Add a --compile option to pfunct which produces compileable
output for function prototypes in an object file.
- Miscellaneous bug fixes
