This release aligns XED with Intel® SDM Revision 090 and the latest Intel Software Security Guidance.

Key ISA Updates

  • Added support for the IBHF instruction.
  • Dropped Lunar Lake (LNL) chip configuration (ISA alias of Arrow Lake).

General Improvements

  • Introduced systematic API input validation across XED's APIs, with explicit precondition checks to improve robustness against invalid inputs and misuse.
    Users can disable API validation using the --no-api-check build knob.
  • Extended xed_assert() coverage across internal APIs for improved diagnostics in assert builds.
  • Updated build support for Clang 20.
  • Enhanced xed_to_db.py with a version field in JSON output and data integrity validation for nested structures.
  • Introduced APX encoder precondition handling for NF (No Flags) instructions, which now implicitly enforces EVEX encoding.

Fixes

  • Fixed the --no-cet build option.
