Compiler Option: -vec

Enables vector optimizations by the compiler.

Syntax
   -vec < level >

Parameters
   level
      The level of vectorization: (0 | NONE) | 1 | 2.

Description
   The -vec compiler option enables multiple levels of optimizations by 
   searching for multiple scalar expressions that can be merged into a 
   single vector expression. If this option is not specified, the default 
   is -vec 0.

   -vec 0 | none will disable vector optimizations.

   -vec 1 will enable complete expression merging vectorization.

   -vec 2 includes -vec 1 but also enables intra-expression vectorization.

   This option is dependent on the -fpu SSE command line option.  
   Attempting to enable vector optimizations without using -fpu SSE will 
   generate an error.
