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.
