Intel® C++ Compiler XE 13.1 User and Reference Guides
Enables or disables vectorization.
All
Linux and OS X: | -vec -no-vec |
Windows: | /Qvec /Qvec- |
None
-vec |
Vectorization is enabled. |
This option enables or disables vectorization.
To disable vectorization, specify -no-vec (Linux* OS and OS X*) or /Qvec- (Windows* OS).
To disable the SIMD transformations, specify option -no-simd (Linux OS and OS X) or /Qsimd- (Windows OS).
Using this option enables vectorization at default optimization levels for both Intel® microprocessors and non-Intel microprocessors. Vectorization may call library routines that can result in additional performance gain on Intel microprocessors than on non-Intel microprocessors. The vectorization can also be affected by certain options, such as /arch or /Qx (Windows OS) or -m or -x (Linux OS and OS X).
