Can I use the Forte C compiler -fast option to optimize the driver performance?
The -fast option is really a macro option that invokes several different options. Among them are -native, which includes -xchip, -xcache, and -xarch. For portability reasons, compile with as few platform-dependent options as possible. However, for performance reasons, it might be worthwhile to experiment with the -fast option. In such a case, overwrite the -xarch option with the preferred instruction set architecture (ISA) setting (e.g. -xarch=v8plusa for 32-bit drivers; -xarch=v9 for 64-bit drivers) because the -native setting depends on the version of the compiler.
