Function creusot_contracts::std::arch::x86_64::_mm_getcsr

pub unsafe fn _mm_getcsr() -> u32

👎Deprecated since 1.75.0: see _mm_getcsr documentation - use inline assembly instead

Available on x86-64 only.

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.
