      [no-wasm] Skip wasm tests if wasm is disabled · 18136654
      Clemens Backes authored
      This CL introduces a test runner flag to detect if webassembly has been
      disabled. Since all tests that require wasm are alrady skipped in
      lite mode, we introduce a has_webassembly flag for the test runner which
      checks for v8_enable_webassembly=true and v8_enable_lite_mode=false.
      As a drive-by, we also do not set the V8_ENABLE_WEBASSEMBLY
      preprocessor flag if lite mode is enabled.
      
      The status files are updated by splitting wasm tests from the
      "lite_mode" section and checking for "not has_webassembly" instead.
      
      Note that the v8_enable_webassembly=false configuration is not tested
      on any bot currently, but I will make sure that all tests keep passing
      on further changes in this configuration.

      [wasm-simd][scalar-lowering] Fix lowering of narrowing · 894bf6df
      Ng Zhi An authored
      Narrowing operations need to sign extend the result.
      
      E.g. for narrowing uint16 to uint8, we compare uint16 to uint8 max,
      0xff. The final result should be 0xffffffff (sign extended) since we
      try to keep nodes in their sign extended form, to work well with
      the rest of the lowering operations.
      
      With this, we pass the last spec test (that is not ignored),
      simd_conversions.

      [wasm-simd] Stage SIMD · 1d2726dd
      Ng Zhi An authored
      SIMD has been pretty stable for a while now, we are not expecting big
      changes (like opcode renumbers), there might be new instructions added,
      and they will all be backwards-compatible.
      
      The reference interpreter in the SIMD proposal is now capable of
      generating JS files for all test cases, so we can now run them.
      
      There is a bit of tweaking necessary, since SIMD tests are in
      tests/core/simd subfolder in the spec, so we need to change the glob
      into a find that will traverse into subdirectory.

      [wasm] Check size of tables dynamically · 47434265
      Andreas Haas authored
      We used to check the size of tables at compile time, and threw a
      CompilationError if a given size exceeded the implementation-defined
      limit. However, the spec defines that an error should only be thrown
      when the implementation-defined limit is reached, which is either at
      instantiation time of during runtime at a table.grow.
      
      With this CL the V8 implementation becomes spec compliant in this
      regard.
