  • Applied the Fixed-width SIMD proposal.
  • Provided options to toggle proposals for the compiler and runtime.
    • --enable-bulk-memory to enable bulk-memory operations proposal.
    • --enable-reference-types to enable reference types proposal.
    • --enable-simd to enable SIMD proposal.
    • --enable-all to enable all supported proposals.
  • Supported roundeven intrinsic in LLVM 11.

Fixed issues:

  • Used std::filesystem::path for all paths.
  • Interpreter
    • Fixed call_indirect table index checking in the validation phase.
    • Removed redundant reinterpret_cast in interpreter.
  • AOT compiler
    • Forced unalignment in load and store instructions in AOT.
