Struct melior::ExecutionEngine

pub struct ExecutionEngine { /* private fields */ }

An execution engine.

Implementations

impl ExecutionEngine

pub fn new( module: &Module<'_>, optimization_level: usize, shared_library_paths: &[&str], enable_object_dump: bool ) -> Self

Creates an execution engine.

pub fn lookup(&self, name: &str) -> *mut ()

Searches a symbol in a module and returns a pointer to it.

pub unsafe fn invoke_packed( &self, name: &str, arguments: &mut [*mut ()] ) -> Result<(), Error>

Invokes a function in a module. The arguments argument includes pointers to results of the function as well as arguments.

Safety

This function modifies memory locations pointed by the arguments argument. If those pointers are invalid or misaligned, calling this function might result in undefined behavior.

pub unsafe fn register_symbol(&self, name: &str, ptr: *mut ())

Register a symbol. This symbol will be accessible to the JIT’d codes.

Safety

This function makes a pointer accessible to the execution engine. If a given pointer is invalid or misaligned, calling this function might result in undefined behavior.

pub fn dump_to_object_file(&self, path: &str)

Dumps a module to an object file.

Trait Implementations

impl Drop for ExecutionEngine

fn drop(&mut self)

Executes the destructor for this type.
