Required Associated Types§

Source

type Builder<'a>: Builder<Type = Self::Type, Value = Self::Value, StackSlot = Self::StackSlot, BasicBlock = Self::BasicBlock, Function = Self::Function> where Self: 'a

Source

type FuncId: Copy + Eq + Hash + Debug

Required Methods§

Source

fn ir_extension(&self) -> &'static str

Source

fn set_module_name(&mut self, name: &str)

Source

fn config(&self) -> &BackendConfig

Returns the current backend configuration.

Source

fn apply_config(&mut self, config: BackendConfig)

Applies the given configuration snapshot.

Backends should apply any side-effects (e.g. toggling ASM verbosity) here.

Source

fn dump_ir(&mut self, path: &Path) -> Result<()>

Source

fn dump_disasm(&mut self, path: &Path) -> Result<()>

Source

fn is_aot(&self) -> bool

Source

fn function_name_is_unique(&self, name: &str) -> bool

Source

fn build_function( &mut self, name: &str, ret: Option<Self::Type>, params: &[Self::Type], param_names: &[&str], linkage: Linkage, ) -> Result<(Self::Builder<'_>, Self::FuncId)>

Source

fn verify_module(&mut self) -> Result<()>

Source

fn optimize_module(&mut self) -> Result<()>

Source

fn write_object<W: Write>(&mut self, w: W) -> Result<()>

Source

fn jit_function(&mut self, id: Self::FuncId) -> Result<usize>

Source

fn function_name(&self, id: Self::FuncId) -> Option<&str>

Returns the name of a compiled function by its ID.

Source

fn clear_ir(&mut self) -> Result<()>

Clears the IR module, freeing memory used by IR representations.

This does not free JIT-compiled machine code, so previously obtained function pointers remain valid. The module is left in a state where new functions can be translated.

Source

unsafe fn free_function(&mut self, id: Self::FuncId) -> Result<()>

Source

unsafe fn free_all_functions(&mut self) -> Result<()>

Provided Methods§

Source

fn finalize_debug_info(&mut self) -> Result<()>

Finalizes any pending debug info metadata.

Must be called before verification, optimization, or code emission.

Source

fn function_sizes(&self) -> Vec<(String, usize)>

Returns the estimated sizes of compiled functions as (name, size) pairs.

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
