Hi, The v1.24 release of pahole and its friends is out, with faster BTF generation by parallelizing the encoding part in addition to the previoulsy parallelized DWARF loading, support for 64-bit BTF enumeration entries, signed BTF encoding of 'char', exclude/select DWARF loading based on the language that generated the objects, etc. Main git repo: git://git.kernel.org/pub/scm/devel/pahole/pahole.git Mirror git repo: https://github.com/acmel/dwarves.git tarball + gpg signature: https://fedorapeople.org/~acme/dwarves/dwarves-1.24.tar.xz https://fedorapeople.org/~acme/dwarves/dwarves-1.24.tar.bz2 https://fedorapeople.org/~acme/dwarves/dwarves-1.24.tar.sign Thanks a lot to all the contributors and distro packagers, you're on the CC list, I appreciate a lot the work you put into these tools, Best Regards, BTF encoder: - Add support to BTF_KIND_ENUM64 to represent enumeration entries with more than 32 bits. - Support multithreaded encoding, in addition to DWARF multithreaded loading, speeding up the process. Selected just like DWARF multithreaded loading, using the 'pahole -j' option. - Encode 'char' type as signed. BTF Loader: - Add support to BTF_KIND_ENUM64. pahole: - Introduce --lang and --lang_exclude to specify the language the DWARF compile units were originated from to use or filter. Use case is to exclude Rust compile units while aspects of the DWARF generated for it get sorted out in a way that the kernel BPF verifier don't refuse loading the BTF generated from them. - Introduce --compile to generate compilable code in a similar fashion to: bpftool btf dump file vmlinux format c > vmlinux.h As with 'bpftool', this will notice type shadowing, i.e. multiple types with the same name and will disambiguate by adding a suffix. - Don't segfault when processing bogus files.
