Intrinsic and -msse2

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello,

I am trying to get a project compiled that utilises intrinsics.

The intrisic code is guarded by code that detects the processor type.

Now, the problem is that I need to turn on -msse2 to have access to the __m128i datatype, but turning that on seems to cause the compiler to convert some code to include the cvtsi2sd instruction which is not supported on athlon systems.

So... Is there a way that I can turn on SSE2 intrinsic support without getting the compiler to optimise for SSE2 instructions in general code?

Regards,

Matthew
