dwarves-1.27-1.el10 RPM for s390x

From CentOS Stream 10 AppStream for s390x

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

* Wed Jun 26 2024 Viktor Malik <vmalik@redhat.com> - 1.27-1
  - Resolves: RHEL-45148
  - Add gating.yaml
  - Add "Provides: pahole"
  - 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.
  - New release: v1.27
  - Reproducible parallel builds: multiple runs with different number of loading/encoding threads produce the same result.
  - Inject kfunc decl tags into BTF from the BTF IDs ELF section in the Linux kernel vmlinux file.
  - Sanitize unsupported DWARF int type with greater-than-16 byte, as BTF doesn't support it.
  - Initial support for BTF_KIND_DECL_TAG in the BTF loader, adding support in pfunct output.
  - Fix hole discovery with inheritance in C++.
* Mon Jun 24 2024 Troy Dawson <tdawson@redhat.com> - 1.25-6
  - Bump release for June 2024 mass rebuild

  - 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

* 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
