/qarch Compiler Option

Syntax: Default:
/qarch=option /qarch=486

Use /qarch to specify the architecture on which the executable program will be run. The object produced contains instructions appropriate for the architecture.

option can be one of the following:

x86 Any 32-bit x86 architecture
486 Any architecture supporting the 486 instruction set
pentium Any architecture supporting the Pentium instruction set
pentium2 Any architecture supporting the PentiumII or PentiumPro instruction set.

Performance Consideration
For code that makes heavy use of floating-point types, specifying PentiumII or PentiumPro architectures can increase execution performance.
