Key Changes:

  • Added ElectronicCodeBookAESNode intrinsic and LIR ops (AMD64ElectronicCodeBookAESEncryptOp, AMD64ElectronicCodeBookAESDecryptOp) using AVX512 VAES instructions for ECB AES encrypt/decrypt.
  • Added EVEX-encoded AES instructions (EVAESENC, EVAESDECLAST, etc.) in AMD64Assembler.
  • Updated GraphBuilder plugins to use ECB intrinsics instead of HotSpot foreign calls.
  • Removed ECB foreign call descriptors and VM config fields.
  • Updated tests to check ElectronicCodeBookAESNode.isSupported().
  • Integrated ECB stubs in SubstrateVM for AMD64.
