      Test shift counts for int8_t and int16_t that are too large w/ explicit masks · 7d03ddcc
      Ian Romanick authored
      The SPIR-V spec says:
          The result is undefined if Shift is greater than or equal to the bit
          width of the components of Base.
      However, other APIs specify that the shift count is modulo the bitwidth
      of Base.  To achieve this in SPIR-V, translators will insert explicit
      masks of Shift with 7, 15, 31, or 63 depending on the type of Base.
      These two tests verify that these explicit masks are respected for 8-bit
      and 16-bit Base.
      The Intel PRMs imply that on BDW and earlier, Shift is implicitly
      masked with 31 when Base is 32-bits or smaller.  Optimizations in Mesa
      remove explicit masks that match the size of Base (e.g., x << (y & 15)
      for 16-bit Base) with the assumption that the native instruction will
      implicitly do this mask.
      The Intel PRMs explicitly say that on SKL and later, Shift is
      implicitly masked with the proper mask for the size of Base.
      The results of this test seem to contradict the PRMs.  If the PRMs are
      correct, the test should pass on every SKL+ platform, and it should fail
      on BDW.  Earlier platforms either don't support shaderInt16 or
      shaderInt8, or don't support Vulkan.  However, the total list of
      failures is:
      The 16-bit test passes on BDW, and the 8-bit test fails on BDW and
      v2: Update include path.  Update file name to reflect that it contains
      both Int8 and Int16 tests.  Suggested by Caio.
