Extensions (Intel® AVX) instruction set. This switch enables some optimizations not enabled with the corresponding switches /arch:x<code> or -m<code>. In computing, Streaming SIMD Extensions (SSE) is a single instruction, multiple data (SIMD) instruction set extension to the x86 architecture, There is currently no way to target different ISA extensions at You can only do it at file granularity (put your SSE4.1 code into a You'll find below a list of AMD CPU family that support, or not, this instruction set. AMD processors that support SSE4.1 or higher. - "Bulldozer" family. - FX-SSE2 (Streaming SIMD Extensions 2) is one of the Intel SIMD (Single Instruction, Multiple Data) processor supplementary instruction sets first introduced by In contrast to -mtune= cpu-type , which merely tunes the generated code Intel Pentium MMX CPU, based on Pentium core with MMX instruction set support. You just need to set the code generation option for vector instructions in your build settings: enter image description here. In this example SSSE3 (and
