In Intel® processors, the flush-to-zero (
) flags in the
register are used to control floating-point calculations. Intel® Streaming SIMD Extensions (Intel® SSE) and Intel® Advanced Vector Extensions (Intel® AVX) instructions, including scalar and vector instructions, benefit from enabling the
flags. Floating-point computations using the Intel® SSE and Intel® AVX instructions are accelerated when the
flags are enabled. This improves the application's performance.
