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.
