This release aligns XED with Intel® ISE Revision 061 and Intel® AVX10.2 Revision 7.0.

Key ISA Updates

  • Dropped USER-MSR support from the Diamond Rapids and Nova Lake chips.
  • Moved APX-promoted USER-MSR variants to the FUTURE XED chip and fixed their XED extension name.
  • Updated VCVTHF82PH exception type.

General Improvements

  • Switched the Windows XED example tool from static to dynamic dbghelp.dll loading, restricting resolution to trusted locations.
  • Replaced the obsolete --vc-dir build knob with a working --toolchain-vs option for selecting a Visual Studio installation root directory.
  • Expanded xed_to_db.py metadata export with structured CPUID records and list-valued reg_required data for ranged REG constraints, and added usage guidance to pysrc/README.md.

Fixes

  • Improved EVEX immediate sign-extension in the disassembler.
