-fast  enable -xP -O3 -ipo -no-prec-div -static
-Ob<n> control inline expansion:
    n=0  disables inlining
    n=1  inline functions declared with __inline, and perform C++ 
        inlining
    n=2  inline any function, at the compiler's discretion (same
        as -ip)
-falias       assume aliasing in program (DEFAULT)
--
-ipo[n] enable multi-file IP optimizations (between files)
-ipo-c  generate a multi-file object file (ipo_out.o)
-ipo-S  generate a multi-file assembly file (ipo_out.s)

Modify the behavior of IP:
-ip-no-inlining    disable full and partial inlining (requires
-ip or -ipo)
-ip-no-pinlining   disable partial inlining (requires -ip or
-ipo)
-ipo-separate      create one object file for every source file
               (overrides -ipo[n])

Other Advanced Performance Options:
-unroll[n]      set maximum number of times to unroll loops.  Omit n to use
               default heuristics.  Use n=0 to disable loop unroller.
-unroll [n]     set maximum number of times to unroll loops.  Omit n to use
