Intel® Fortran Compiler 17.0 Developer Guide and Reference
Determines whether MOVBE instructions are generated for certain Intel processors.
Not available on Intel® 64 architecture targeting the Intel® Xeon Phi™ coprocessor x100 product family (formerly code name Knights Corner)
Linux and macOS: | -minstruction=[no]movbe |
Windows: | /Qinstruction:[no]movbe |
None
–minstruction=nomovbe |
The compiler does not generate MOVBE instructions for Intel® Atom™ processors. |
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.
