Struct x86_64_xsave::MxcsrRegisterValue

#[repr(transparent)]
pub struct MxcsrRegisterValue(_);

The 32-bit MXCSR register contains control and status information for SSE, SSE2, and SSE3 SIMD floating-point operations.

This register contains:-

• flag and mask bits for SIMD floating-point exceptions;
• rounding control field for SIMD floating-point operations;
• flush-to-zero flag that provides a means of controlling underflow conditions on SIMD floating-point operations;
• denormals-are-zeros flag that controls how SIMD floating-point instructions handle denormal source operands
