  • Fixed parsing of switchjmp for vISA assembly,
  • Fixed SPIRV reader constructing reference type debug metadata,
  • Initial support for interprocedural TPM pass,
  • Introduction of new entry in IGC constant folder for IBFE,
  • Lower genx.*mul.sat intrinsics since integer mul.sat is not supported,
