![]() These instructions allow calculation with 128-bit vectors of single-precision, double-precision and 1, 2, 4 or 8-byte integer values, as well as single-precision and double-precision scalar floating-point values.ĪVX introduced an alternative instruction encoding for vector and floating-point scalar instructions. The default mode uses SSE2 instructions for scalar floating-point and vector calculations. The processor extensions have the following characteristics: When you use /clr to compile, /arch has no effect on code generation for managed functions. arch only affects code generation for native functions. In general, more recently introduced processors may support extensions beyond the ones supported by older processors, although you should consult the documentation for a particular processor or test for instruction set extension support using _cpuid before executing code using an instruction set extension. The /arch option enables the use of certain instruction set extensions, particularly for vector calculation, available in processors from Intel and AMD. SyntaxĮnables the use of Intel Advanced Vector Extensions instructions.Įnables the use of Intel Advanced Vector Extensions 2 instructions.Įnables the use of Intel Advanced Vector Extensions 512 instructions. For more information on /arch for other target architectures, see /arch (x86), /arch (ARM64), and /arch (ARM). Specifies the architecture for code generation on 圆4.
