Summary

Debugging Information Manipulation Tools (pahole & friends)

Description

dwarves is a set of tools that use the debugging information inserted in ELF binaries by compilers such as GCC, used by well known debuggers such as GDB, and more recent ones such as systemtap. Utilities in the dwarves suite include pahole, that can be used to find alignment holes in structs and classes in languages such as C, C++, but not limited to these. It also extracts other information such as CPU cacheline alignment, helping pack those structures to achieve more cache hits. These tools can also be used to encode and read the BTF type information format used with the Linux kernel bpf syscall, using 'pahole -J' and 'pahole -F btf'. A diff like tool, codiff can be used to compare the effects changes in source code generate on the resulting binaries. Another tool is pfunct, that can be used to find all sorts of information about functions, inlines, decisions made by the compiler about inlining, etc. One example of pfunct usage is in the fullcircle tool, a shell that drivers pfunct to generate compileable code out of a .o file and then build it using gcc, with the same compiler flags, and then use codiff to make sure the original .o file and the new one generated from debug info produces the same debug info. Pahole also can be used to use all this type information to pretty print raw data according to command line directions. Headers can have its data format described from debugging info and offsets from it can be used to further format a number of records. The btfdiff utility compares the output of pahole from BTF and DWARF to make sure they produce the same results.

Changelog

* Tue Feb 27 2024 Arnaldo Carvalho de Melo <acme@redhat.com> - 1.26-1 - New release: v1.26 - When expanding types using 'pahole -E' do it for union and struct typedefs and for enums too. - Print number of holes, bit holes and bit paddings in class member types. - Introduce --contains_enumerator=ENUMERATOR_NAME: - Fix pretty printing using DWARF, waiting for a CU with both class (-C) and a specified "type_enum". - Add support for DW_TAG_constant in the DWARF loader, first seen in Go DWARF. - Fix loading DW_TAG_subroutine_type generated by the Go compiler. - Fix loading of 32-bit signed enums from BTF. - Add 'pahole --btf_features' to allow consumers to specify an opt-in set of features they want to use in BTF encoding. - Parallelize loading BTF and DWARF, speeding up a bit btfdiff. - Do type expansion to cover "private" types and enumerations in btfdiff. * Wed Jan 24 2024 Fedora Release Engineering <releng@fedoraproject.org> - 1.25-5 - Rebuilt for https://fedoraproject.org/wiki/Fedora_40_Mass_Rebuild * Fri Jan 19 2024 Fedora Release Engineering <releng@fedoraproject.org> - 1.25-4 - Rebuilt for https://fedoraproject.org/wiki/Fedora_40_Mass_Rebuild * Wed Oct 11 2023 Viktor Malik <vmalik@redhat.com> - 1.25-3 - Migrate license to SPDX * Wed Jul 19 2023 Fedora Release Engineering <releng@fedoraproject.org> - 1.25-2 - Rebuilt for https://fedoraproject.org/wiki/Fedora_39_Mass_Rebuild * Sat Apr 08 2023 Arnaldo Carvalho de Melo <acme@redhat.com> - 1.25-1 - New release: v1.25 - Support for DW_TAG_unspecified_type more generally. - Make sure struct member offsets are in ascending order. Rust BTF needs this. - Support C atomic types (DW_TAG_atomic_type). - Initial support for DW_TAG_LLVM_annotation, used for BTF type tags, for __rcu, __user, etc - Exclude functions with the same name (static functions in different CUs), inconsistent prototypes or not following calling convention. - Allow generation of BTF for optimized functions, those that end with a .isra*, .constprop*. - Support 'pahole --lang=/--lang_exclude=asm' - Support --compile from DWARF in addition to from BTF. - Exclude RUST CUs in 'btfdiff', as those are not yet being BTF encoded. * Fri Feb 17 2023 Arnaldo Carvalho de Melo <acme@redhat.com> - 1.24-3 - Backport the DW_TAG_unspecified_type support while 1.25 gets ready wrt optimized functions support * Thu Jan 19 2023 Fedora Release Engineering <releng@fedoraproject.org> - 1.24-2 - Rebuilt for https://fedoraproject.org/wiki/Fedora_38_Mass_Rebuild * Wed Aug 17 2022 Arnaldo Carvalho de Melo <acme@redhat.com> - 1.24-1 - New release: v1.24 - Add support to BTF_KIND_ENUM64. - Support multithreaded BTF encoding. - Encode char type as signed in BTF. - Introduce --lang and --lang_exclude to pahole. - Introduce --compile to pahole. - Don't segfault when processing bogus files. * Thu Jul 21 2022 Fedora Release Engineering <releng@fedoraproject.org> - 1.23-3 - Rebuilt for https://fedoraproject.org/wiki/Fedora_37_Mass_Rebuild
