Changes since 1.24:
DWARF loader:
- Support for DW_TAG_unspecified_type more generally, that in binutils
2.40 is used for assembly functions, resulting in BTF encoding problems
when building the Linux kernel.
- Make sure struct member offsets are in ascending order. This is part of
the set of changes to support encoding BTF for Rust for use with the
Linux kernel, where the BTF verifier considers invalid offset unordered
struct members.
- Support C atomic types (DW_TAG_atomic_type), that are not used in the
Linux kernel but is present in user space components such as Open
VSwitch.
BTF loader:
- Initial support for DW_TAG_LLVM_annotation, used for BTF type tags, to
encode things like __rcu, __user annotations in the Linux kernel. This
is still in flux with changes in how these are encoded that resulted
from the discussion to support this in gcc in addition to in clang,
where it was first designed.
BTF encoder:
- 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* suffix (inter procedural scalar replacement of aggregates) or
.constprop* (constant propagation).
Pretty printer:
- For now the DW_TAG_LLVM_annotation tags are being suppressed, so the
output from BTF and DWARF matches, further work is planned to support it
so that the output matches the original source code and can be
recompilable, resulting in the same DWARF info.
- Support C atomic types, allowing the generation of source code that can
be compiled with resulting DWARF info matching the original source code.
pahole:
- Support --lang=/--lang_exclude=asm, the DW_LANG_ define for assembly is
out of order, special case it to support asking for CUs written in
assembly to be selected or excluded.
- Support suppressing the atomic type modifiers/attributes.
- Allow filtering out functions optimized by the compiler, where the
calling convention isn't the one expected by BPF or arguments are
optimized out.
- Support --compile from DWARF in addition to from BTF, this allows user
space components such as Open VSwitch to use pahole to generate
compilable code for its data structures.
btfdiff:
- Exclude RUST CUs, as those are not yet being BTF encoded.
* Drop patches already applied upstream:
- 00-store-the-CU-being-processed-to-avoid-changing-many-functions.patch
- 01-record-if-a-CU-has-a-DW_TAG_unspecified_type.patch
- 02-encode-DW_TAG_unspecified_type-returning-routines-as-void.patch
