### /qtune Compiler Option

Syntax: | Default:
/qtune=option | /qtune=blend

Use /qtune to specify the type of processor for which the executable program is optimized.

option is one of the following:

386 | Produce object code optimized for 386-class processors
486 | Produce object code optimized for 486-class processors
blend | Produce object code optimized for all x86 processors
pentium | Produce object code optimized for Pentium processors
pentium2 | Produce object code optimized for PentiumII and PentiumPro processors

The code can run on any x86 processor, but is specifically tuned for the target processor. The compiler also performs optimizations that help other processors if those optimizations do not in turn detract from the performance of the target processor. For example, code optimized for a 486 processor also includes any Pentium optimizations that do not diminish 486 execution.

If you do not know what processor your application will be run on, specify /qtune=blend. The compiler includes optimizations that help all x86 processors, but specifically improve execution on Pentium, PentiumII and PentiumPro processors.
