  14   VcCheck.c

  16 Abstract:
  17
  18   We have found problems with the Visual C++ SP4 and the /O1 flag.
  19   If this tests ask a question you have the wrong version of Visual C++
  20   on your system
  21
  22   This test assumes the tools are being compiled with the same complier
  23   as the Tiano code.
  24
  25   Please see $(EFI_SOURCE)\EFI2.0 Developer's Manual.doc to get the
  26   correct version of Visual C++

  40 Routine Description:
  41   This routine is used to test for compiler isseus with /O1.
  42   If the /O1 compiler option, and C2.dll is got from Visual C++ SP5
  43   (version: 6.00.8168.0), the assember codes after default branch will be
  44   losted. (Execute "cl Visual Ccheck.c /O1 /FAsc" to get detail information)

  46 Arguments:
  47   Value - Test case
  48
  49 Returns:
  50   Test to see if comiler error is present.
