ply is a light-weight dynamic tracer for Linux that leverages the kernel's
BPF VM in concert with kprobes/tracepoints to attach probes to arbitrary
points in the kernel.
Most tracers that generate BPF bytecode are based on the LLVM-based BCC
toolchain; ply on the other hand has no external dependencies outside libc,
making it suitable for use on constrained embedded systems.
Currently ply supports x86_64, aarch64, arm, riscv64, riscv32, powerpc,
mips(el), and mips64(el) architectures.

Different from OPKG, APK uses a deterministic version schema which chips
the version into chunks and compares them individually. This enforces a
certain schema which was previously entirely flexible.
- Releases are added at the very and end prefixed with an `r` like
`1.2.3-r3`.
- Hashes are prefixed with a `~` like `1.2.3~abc123`.
- Dates become semantic versions, like `2024.04.01`
- Extra tags are possible like `_git`, `_alpha` and more.

Build and package kernel self-tests used for BPF testing, program and JIT
development. This package, together with the existing 'kmod-bpf-test', was

Currently this includes only 'test_verifier'; building 'test_progs' will

Changes:
* The ELF linker will now generate a warning message if the stack is made
executable. Similarly it will warn if the output binary contains a
segment with all three of the read, write and execute permission
bits set. These warnings are intended to help developers identify
programs which might be vulnerable to attack via these executable
memory regions.
The warnings are enabled by default but can be disabled via a command
line option. It is also possible to build a linker with the warnings
disabled, should that be necessary.
* The ELF linker now supports a --package-metadata option that allows
embedding a JSON payload in accordance to the Package Metadata
specification.
* In linker scripts it is now possible to use TYPE=<type> in an output
section description to set the section type value.
* The objdump program now supports coloured/colored syntax
highlighting of its disassembler output for some architectures.
(Currently: AVR, RiscV, s390, x86, x86_64).
* The nm program now supports a --no-weak/-W option to make it ignore
weak symbols.
* The readelf and objdump programs now support a -wE option to prevent
them from attempting to access debuginfod servers when following
links.
* The objcopy program's --weaken, --weaken-symbol, and
--weaken-symbols options now works with unique symbols as well.

Changelog:
Assembler:
General:
* Add support for the LoongArch architecture.
* Add an option to control how multibyte characters are handled in
the assembler. Using the option warnings can be generated when
such characters are encountered in symbol names, or anywhere in
the input source file(s).
AArch64 and ARM:
* Add support for more system registers.
* Add support for Scalable Matrix Extension.
* Add support for Cortex-R52+, Cortex-A510, Cortex-A710,
Cortex-X2, Cortex-A710 cores.
* Add support for 'v8.7-a', 'v8.8-a', 'v9-a', 'v9.1-a',
'armv9.2-a' and 'armv9.3-a' architecture extensions.
X86:
* Add a command-line option to encode aligned vector move as
unaligned vector move.
* Add support for Intel AVX512_FP16 instructions.
* The outputs of .ds.x directive and .tfloat directive with hex
input have been reduced from 12 bytes to 10 bytes to match the
output of .tfloat directive.
Linker:
* Add support for the LoongArch architecture.
* Add -z pack-relative-relocs/-z no pack-relative-relocs to x86 ELF
linker to pack relative relocations in the DT_RELR section.
* Add -z indirect-extern-access/-z noindirect-extern-access to x86
ELF linker to control canonical function pointers and copy
relocation.
Other Binary Tools:
* elfedit: Add --output-abiversion option to update ABIVERSION.
* Tools which display symbols or strings (readelf, strings, nm,
objdump) have a new command line option which controls how unicode
characters are handled. By default they are treated as normal for
the tool. Using --unicode=locale will display them according to
the current locale. Using --unicode=hex will display them as hex
byte values, whilst --unicode=escape will display them as escape
sequences. In addition using --unicode=highlight will display
them as unicode escape sequences highlighted in red (if supported
by the output device).
* readelf -r dumps RELR relative relocations now.
* Support for efi-app-aarch64, efi-rtdrv-aarch64 and
efi-bsdrv-aarch64 has been added to objcopy in order to enable
UEFI development using binutils.
* ar: Add --thin for creating thin archives. -T is a deprecated
alias without diagnostics. In many ar implementations -T has a
different meaning, as specified by X/Open System Interface.
