We are pleased to announce a significant new release of Dyninst and its component tool kits. This release includes some major new features (e.g., more ARM/64 support, Intel KNL support) and, finally (!), a DataflowAPI manual.

In addition, we've made a lot of code analysis improvement, performance improvements, internal code clean ups, and bug
fixes.

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.

BUG FIXES

• 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

KNOWN ISSUES

• ppc64 rewriter mode does not yet handle 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.
