Expand description

Top-level machine backend trait, which wraps all monomorphized code and allows a virtual call from the machine-independent Function::compile().

Required methods

fn compile_function(
    &self,
    func: &Function,
    want_disasm: bool
) -> CodegenResult<MachCompileResult>[src]

Compile the given function.

fn flags(&self) -> &Flags[src]

Return flags for this backend.

fn isa_flags(&self) -> Vec<Value>[src]

Get the ISA-dependent flag values that were used to make this trait object.

fn hash_all_flags(&self, hasher: &mut dyn Hasher)[src]

Hashes all flags, both ISA-independent and ISA-dependent, into the specified hasher.

fn triple(&self) -> Triple[src]

Return triple for this backend.

fn name(&self) -> &'static str[src]

Return name for this backend.

fn reg_universe(&self) -> &RealRegUniverse[src]

Return the register universe for this backend.

fn unsigned_add_overflow_condition(&self) -> IntCC[src]

Machine-specific condcode info needed by TargetIsa. Condition that will be true when an IaddIfcout overflows.

fn unsigned_sub_overflow_condition(&self) -> IntCC[src]

Machine-specific condcode info needed by TargetIsa. Condition that will be true when an IsubIfcout overflows.

Provided methods

fn emit_unwind_info(
    &self,
    _result: &MachCompileResult,
    _kind: UnwindInfoKind
) -> CodegenResult<Option<UnwindInfo>>[src]

Produces unwind info based on backend results.

fn create_systemv_cie(&self) -> Option<CommonInformationEntry>[src]

Creates a new System V Common Information Entry for the ISA.

fn map_reg_to_dwarf(&self, _: Reg) -> Result<u16, RegisterMappingError>[src]

Maps a regalloc::Reg to a DWARF register number.
