# minstruction, Qinstruction

Determines whether MOVBE instructions are generated for certain Intel® processors. This feature is only available for ifort.

## Syntax

Linux: | -minstruction=[no]movbe

macOS: | -minstruction=[no]movbe

Windows: | /Qinstruction:[no]movbe

## Arguments

None

## Default

–minstruction=nomovbe or/Qinstruction:nomovbe | The compiler does not generate MOVBE instructions for Intel Atom® processors.

## Description

This option determines whether MOVBE instructions are generated for Intel Atom® processors. To use this option, you must also specify [Q]xATOM_SSSE3 or [Q]xATOM_SSE4.2.

If -minstruction=movbe or /Qinstruction:movbe is specified, the following occurs:

- MOVBE instructions are generated that are specific to the Intel Atom® processor.

- Generated executables can only be run on Intel Atom® processors or processors that support Supplemental Streaming SIMD Extensions 3 (Intel® SSSE3) or Intel® Streaming SIMD Extensions 4.2 (Intel® SSE4.2) and MOVBE.

If -minstruction=nomovbe or /Qinstruction:nomovbe is specified, the following occurs:

- The compiler optimizes code for the Intel Atom® processor, but it does not generate MOVBE instructions.

- Generated executables can be run on non-Intel Atom® processors that support Intel® SSE3 or Intel® SSE4.2.
