Source 
pub struct AssemblerX64 {
    pub inner: VecAssembler<X64Relocation>,
    pub simd_arch: Option<CpuFeature>,
    pub target: Option<Target>,
}

Fields§

§inner: VecAssembler<X64Relocation>

the actual inner

§simd_arch: Option<CpuFeature>

the simd instructions set on the target. Currently only supports SSE 4.2 and AVX

§target: Option<Target>

Full Target cpu

Implementations§

Source§

impl AssemblerX64

Source

fn new(baseaddr: usize, target: Option<Target>) -> Result<Self, CompileError>

Source

fn finalize(self) -> Result<Vec<u8>, DynasmError>

Methods from Deref<Target = VecAssembler<X64Relocation>>§

pub fn reserve_ops(&mut self, additional: usize)

Reserve capacity for at least additional instruction bytes to be inserted

pub fn new_dynamic_label(&mut self) -> DynamicLabel

Create a new dynamic label ID

pub fn commit(&mut self) -> Result<(), DynasmError>

Resolves any relocations emitted to the assembler before this point. If an impossible relocation was specified before this point, returns them here.

pub fn alter(&mut self) -> UncommittedModifier<'_>

Use an UncommittedModifier to alter uncommitted code. This does not allow the user to change labels/relocations.

pub fn labels(&self) -> &LabelRegistry

Provides access to the assemblers internal labels registry

pub fn labels_mut(&mut self) -> &mut LabelRegistry

Provides mutable access to the assemblers internal labels registry

pub fn take(&mut self) -> Result<Vec<u8>, DynasmError>

Equivalent of finalize, but allows the VecAssembler’s internal allocations to be reused for the next assembler.

pub fn drain<'a>( &'a mut self, ) -> Result<impl Iterator<Item = u8> + 'a, DynasmError>

Equivalent of take, but instead of allocating a new vector it simply provides a draining iterator over the internal contents.

Trait Implementations§

impl Deref for AssemblerX64

Source§

type Target = VecAssembler<X64Relocation>

The resulting type after dereferencing.
Source§

fn deref(&self) -> &Self::Target

Dereferences the value.
Source§

impl DerefMut for AssemblerX64

Source§

fn deref_mut(&mut self) -> &mut Self::Target

impl EmitterX64 for AssemblerX64

Source§

fn emit_cmp( &mut self, sz: Size, left: Location<GPR, XMM>, right: Location<GPR, XMM>, ) -> Result<(), CompileError>

Emit a CMP instruction that compares left against right.

Note: callers sometimes pass operands in the opposite order compared to other binary operators. This function performs the comparison as provided (i.e. it emits cmp left, right semantics).
