no_denormals

Temporarily turn off floating point denormals.

Internally, this uses a RAII-style guard to manage the state of certain processor flags. On x86 and x86_64, this sets the flush-to-zero and denormals-are-zero flags in the MXCSR register. On aarch64 this sets the flush-to-zero flag in the FPCR register. In all cases, the register will be reset to its initial state when the guard is dropped.

Usage

use no_denormals::no_denormals;

no_denormals(|| {
	// your DSP code here.
});
