Maximizes speed across the entire program.
IA-32, IntelŪ EM64T, IntelŪ ItaniumŪ architecture
|OFF||The optimizations maximizing speed are not enabled.|
This option maximizes speed across the entire program.
It sets the following options:
On IA-32 and IntelŪ EM64T systems, the -xP (Linux) or /QxP (Windows) option that is set by the fast option cannot be overridden by other command line options. If you specify the fast option and a different processor-specific option, such as -xN (Linux) or /QxN (Windows), the compiler will issue a warning that explains the -xP or /QxP option cannot be overridden.
On these systems, if you want to get the benefit of the
fast option and use a different processor-specific option, specify the
options set by fast individually on the command
line, omitting the -xP or /QxP
For example, if you want to use the processor-specific option -xW (Linux) or /QxW (Windows), do not specify the fast option. Instead, specify the following options:
The options set by the fast option may change from release to release.
