Struct X87

pub struct X87 {
    pub fpr: [[u8; 10]; 8],
    pub top_of_stack: u8,
    pub exception_flags: u64,
    pub condition_codes: u32,
    pub tag_word: u8,
}

x87 state.

Fields

fpr: [[u8; 10]; 8]

80-bit floating-point registers

top_of_stack: u8

status word

exception_flags: u64

exception flags (one flag per byte); Stack fault is excluded because it’s impossible to set SF=1 without causing an exception directly afterwards.

condition_codes: u32

condition codes (one condition code per byte)

tag_word: u8

tag word

Trait Implementations

impl Clone for X87

fn clone(&self) -> X87

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for X87

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for X87

fn default() -> X87

Returns the “default value” for a type.

impl PartialEq for X87

fn eq(&self, other: &X87) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
