[−]Struct x86_64::registers::rflags::RFlags
The RFLAGS register.
Methods
impl RFlags
pub const ID: RFlags
Processor feature identification flag.
If this flag is modifiable, the CPU supports CPUID.
pub const VIRTUAL_INTERRUPT_PENDING: RFlags
Indicates that an external, maskable interrupt is pending.
Used when virtual-8086 mode extensions (CR4.VME) or protected-mode virtual interrupts (CR4.PVI) are activated.
pub const VIRTUAL_INTERRUPT: RFlags
Virtual image of the INTERRUPT_FLAG bit.
Used when virtual-8086 mode extensions (CR4.VME) or protected-mode virtual interrupts (CR4.PVI) are activated.
pub const ALIGNMENT_CHECK: RFlags
Enable automatic alignment checking if CR0.AM is set. Only works if CPL is 3.
pub const VIRTUAL_8086_MODE: RFlags
Enable the virtual-8086 mode.
pub const RESUME_FLAG: RFlags
Allows to restart an instruction following an instrucion breakpoint.
pub const NESTED_TASK: RFlags
Used by iret
in hardware task switch mode to determine if current task is nested.
pub const IOPL_HIGH: RFlags
The high bit of the I/O Privilege Level field.
Specifies the privilege level required for executing I/O address-space instructions.
pub const IOPL_LOW: RFlags
The low bit of the I/O Privilege Level field.
Specifies the privilege level required for executing I/O address-space instructions.
pub const OVERFLOW_FLAG: RFlags
Set by hardware to indicate that the sign bit of the result of the last signed integer operation differs from the source operands.
pub const DIRECTION_FLAG: RFlags
Determines the order in which strings are processed.
pub const INTERRUPT_FLAG: RFlags
Enable interrupts.
pub const TRAP_FLAG: RFlags
Enable single-step mode for debugging.
pub const SIGN_FLAG: RFlags
Set by hardware if last arithmetic operation resulted in a negative value.
pub const ZERO_FLAG: RFlags
Set by hardware if last arithmetic operation resulted in a zero value.
pub const AUXILIARY_CARRY_FLAG: RFlags
Set by hardware if last arithmetic operation generated a carry ouf of bit 3 of the result.
pub const PARITY_FLAG: RFlags
Set by hardware if last result has an even number of 1 bits (only for some operations).
pub const CARRY_FLAG: RFlags
Set by hardware if last arithmetic operation generated a carry out of the most-significant bit of the result.
pub const fn empty() -> RFlags
Returns an empty set of flags
pub const fn all() -> RFlags
Returns the set containing all flags.
pub const fn bits(&self) -> u64
Returns the raw value of the flags currently stored.
pub fn from_bits(bits: u64) -> Option<RFlags>
Convert from underlying bit representation, unless that representation contains bits that do not correspond to a flag.
pub const fn from_bits_truncate(bits: u64) -> RFlags
Convert from underlying bit representation, dropping any bits that do not correspond to flags.
pub const fn is_empty(&self) -> bool
Returns true
if no flags are currently stored.
pub const fn is_all(&self) -> bool
Returns true
if all flags are currently set.
pub const fn intersects(&self, other: RFlags) -> bool
Returns true
if there are flags common to both self
and other
.
pub const fn contains(&self, other: RFlags) -> bool
Returns true
all of the flags in other
are contained within self
.
pub fn insert(&mut self, other: RFlags)
Inserts the specified flags in-place.
pub fn remove(&mut self, other: RFlags)
Removes the specified flags in-place.
pub fn toggle(&mut self, other: RFlags)
Toggles the specified flags in-place.
pub fn set(&mut self, other: RFlags, value: bool)
Inserts or removes the specified flags depending on the passed value.
