opt_vectorize_loops

-

Controls the use of loop vectorizing optimization.

-
Syntax
-

#pragma opt_vectorize_loops on | off | reset -

-
Targets
- All platforms.
-
Remarks
-

If you enable this pragma, the compiler improves loop performance on compilers that support loop vectorization, like the x86 compiler.

-

NOTE Do not confuse loop vectorizing with the vector instructions supported by some chips, like MMX/SSE on x86. For x86, processor-specific instructions and vector instruction sets must be enabled as well.

-

Only the x86 CodeGen settings panel has the Autovectorize loops option, it is not available as an option setting in any other panel.

-

To check this setting, use __option (opt_vectorize_loops), described in Checking Settings. The default setting is off.
