and x86 only.Expand description
Gets the unsigned 32-bit value of the MXCSR control and status register.
Note that Rust makes no guarantees whatsoever about the contents of this register: Rust floating-point operations may or may not result in this register getting updated with exception state, and the register can change between two invocations of this function even when no floating-point operations appear in the source code (since floating-point operations appearing earlier or later can be reordered).
If you need to perform some floating-point operations and check whether they raised an exception, use an inline assembly block for the entire sequence of operations.
