Struct x86_64::registers::rflags::RFlags [−][src]
pub struct RFlags { /* fields omitted */ }
Expand description
The RFLAGS register.
Implementations
Processor feature identification flag.
If this flag is modifiable, the CPU supports CPUID.
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.
Virtual image of the INTERRUPT_FLAG bit.
Used when virtual-8086 mode extensions (CR4.VME) or protected-mode virtual interrupts (CR4.PVI) are activated.
Enable automatic alignment checking if CR0.AM is set. Only works if CPL is 3.
Enable the virtual-8086 mode.
Allows to restart an instruction following an instrucion breakpoint.
Used by iret
in hardware task switch mode to determine if current task is nested.
The high bit of the I/O Privilege Level field.
Specifies the privilege level required for executing I/O address-space instructions.
The low bit of the I/O Privilege Level field.
Specifies the privilege level required for executing I/O address-space instructions.
Set by hardware to indicate that the sign bit of the result of the last signed integer operation differs from the source operands.
Determines the order in which strings are processed.
Enable interrupts.
Set by hardware if last arithmetic operation resulted in a negative value.
Set by hardware if last arithmetic operation resulted in a zero value.
Set by hardware if last arithmetic operation generated a carry ouf of bit 3 of the result.
Set by hardware if last result has an even number of 1 bits (only for some operations).
Set by hardware if last arithmetic operation generated a carry out of the most-significant bit of the result.
Convert from underlying bit representation, unless that representation contains bits that do not correspond to a flag.
Convert from underlying bit representation, dropping any bits that do not correspond to flags.
Convert from underlying bit representation, preserving all bits (even those not corresponding to a defined flag).
Returns true
if there are flags common to both self
and other
.
Returns true
all of the flags in other
are contained within self
.
