For Intel C/C++ Compiler 2.4 Plug-In
and Intel Fortran Compiler 2.4 Plug-In

-G5     optimize for the Intel Pentium(tm) processor
-G6     optimize for the Intel Pentium Pro (tm) processor
-Qip    optimize to eliminate call overhead and create opportunities for
        further optimizations
-Qipo   Equivalent to -ip, but interprocedural optimizations are done
        for the whole program.
-Qprof_gen
        Instrument code for gathering dynamic feedback information.
-Qprof_use
        Use dynamic feedback generated by previous run with -prof_gen.
-Qprof_dir <Directory_name> 
        Directory for holding feedback profile information.
-Qpc 64 Set the hardware floating point significand precision control to
        double precision. (Used for internal representation of intermediate
        results.)
-Qpad   analyze and reorder memory layout for variables and arrays
-Qrct   Changes the rounding mode to truncation for better floating point
        performance
-Qpad_dim n
        Adds n elements to the first dimension of a multidimensional array
-mP2OPT_opt_bblock_stat_limit=10000
        Controls when certain optimizations are disabled due to resource
        constraints. Specifies the size of a routine in intermediate language
        statements.
-QIfdiv-
        Disable software patch for floating-point division flaw
        which exists on some steppings of the Pentium processor.
