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.
