Implementations

impl ArchTraits

pub const fn sp_reg_id(&self) -> u32

Returns stack pointer register id.

pub const fn fp_reg_id(&self) -> u32

Returns stack frame register id.

pub const fn link_reg_id(&self) -> u32

Returns link register id, if the architecture provides it.

pub const fn ip_reg_id(&self) -> u32

Returns instruction pointer register id, if the architecture provides it.

pub const fn hw_stack_alignment(&self) -> u32

Returns a hardware stack alignment requirement.

Note

This is a hardware constraint. Architectures that don’t constrain it would return the lowest alignment (1), however, some architectures may constrain the alignment, for example AArch64 requires 16-byte alignment.

pub const fn has_link_reg(&self) -> bool

Tests whether the architecture provides link register, which is used across function calls. If the link register is not provided then a function call pushes the return address on stack (X86/X64).

pub const fn min_stack_offset(&self) -> u32

Returns minimum addressable offset on stack guaranteed for all instructions.

pub const fn max_stack_offset(&self) -> u32

Returns maximum addressable offset on stack depending on specific instruction.

pub const fn has_reg_type(&self, typ: RegType) -> bool

pub const fn reg_type_to_signature(&self, typ: RegType) -> OperandSignature

pub fn reg_type_to_group(&self, typ: RegType) -> RegGroup

pub fn reg_type_to_size(&self, typ: RegType) -> u32

pub const fn reg_type_to_type_id(&self, typ: RegType) -> TypeId

pub const fn by_arch(arch: Arch) -> &'static Self
