pmovsxwd is not working with Intel C++ compiler

[Uday_Krishna__G_]

Hi,

In my application am trying to use pmovsxwd assembly instruction in MSVC 2008 IDE with Intel C++ compiler. But the instruction not working properly as described in the instruction set guide. Did any one have any idea on this issue?

Weather MSVC 2008 IDE supports the SSE4.1 assembly instructions? If so How to enable SSE4.1 in MSVC?

Am using the MASM assembler with my application.

You probably have an old version of ml.exe assembler.

The best option could be copying the latest version of ml.exe from the most recent revision of Visual Studio.

Surely VS2008 would support sse4.1 after application of service pack.
