Backport upstream bugfixes for clang builds
54228

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++.

Migrate license to SPDX

Rebuilt for https://fedoraproject.org/wiki/Fedora_39_Mass_Rebuild

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.
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.

Backport the DW_TAG_unspecified_type support while 1.25 gets ready wrt optimized functions support

Rebuilt for https://fedoraproject.org/wiki/Fedora_38_Mass_Rebuild

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.
