Release Dyninst 9.2.0 · dyninst/dyninst

New Features

ARM64 SIMD support in instructionAPI
Support for all x86 instruction sets up to Knight's Landing (AVX, AVX2, AVX512)
DataflowAPI now has an official manual
Initial ppc64/little endian support in Symtab, InstructionAPI, ProcControl, and Stackwalker. Add
-Darch_ppc64_little_endian to your CMake command line when building on little-endian ppc64 systems.
New InstructionAPI test framework based on structured fuzzing.
This resulted in finding (and fixing) lots of corner-case
instruction parsing errors. The fuzzer framework, called Peach,
will be released later this year.

PIE binaries should now be rewritten correctly, even if they have a zero base address
Symtab should now correctly file symbols into their associated modules based on the best available DWARF information
Many more fixes in x86 instruction decoding
Enhancements to jump table analysis
PC-relative memory accesses in VEX instructions can now be relocated correctly
Various proccontrol bug fixes
RTlib's DYNINSTos_malloc and DYNINSTos_free should now be signal-safe
RTlib's tramp guard lock/unlock functions should now avoid making implicit function calls
(which are unsafe from tramp guard code)
ppc64 bit rot for create/attach modes is fixed

ppc64 rewriter mode does not handle any code that does not conform to the "caller sets up TOC" model for intermodule calls
Windows 64-bit mode is not yet supported
Windows rewriter mode is not yet supported
Exceptions in relocated code will not be caught
Linux rewriter mode for 32-bit, statically linked binaries does not support binaries with .plt, .rel, or .rela
sections.
Callbacks at thread or process exit that stop the process will deadlock when a SIGSEGV occurs on a thread other than the main thread of a process
InstructionAPI's format() method does not produce AT&T syntax output
Stackwalker is fragile on Windows
Parsing a binary with no functions (typically a single object file) will crash at CodeObject destruction time.
Line information is still filed into incorrect modules for a small fraction of functions in SymtabAPI.
