Struct cton_wasm::FuncTranslator
[−]
[src]
pub struct FuncTranslator { /* fields omitted */ }WebAssembly to Cretonne IL function translator.
A FuncTranslator is used to translate a binary WebAssembly function into Cretonne IL guided
by a FuncEnvironment object. A single translator instance can be reused to translate multiple
functions which will reduce heap allocation traffic.
Methods
impl FuncTranslator[src]
pub fn new() -> Self[src]
Create a new translator.
pub fn translate<FE: FuncEnvironment + ?Sized>(
&mut self,
code: &[u8],
func: &mut Function,
environ: &mut FE
) -> CtonResult[src]
&mut self,
code: &[u8],
func: &mut Function,
environ: &mut FE
) -> CtonResult
Translate a binary WebAssembly function.
The code slice contains the binary WebAssembly function code as it appears in the code
section of a WebAssembly module, not including the initial size of the function code. The
slice is expected to contain two parts:
- The declaration of locals, and
- The function body as an expression.
See the WebAssembly specification.
The Cretonne IR function func should be completely empty except for the func.signature
and func.name fields. The signature may contain special-purpose arguments which are not
regarded as WebAssembly local variables. Any signature arguments marked as
ArgumentPurpose::Normal are made accessible as WebAssembly local variables.
pub fn translate_from_reader<FE: FuncEnvironment + ?Sized>(
&mut self,
reader: BinaryReader,
func: &mut Function,
environ: &mut FE
) -> CtonResult[src]
&mut self,
reader: BinaryReader,
func: &mut Function,
environ: &mut FE
) -> CtonResult
Translate a binary WebAssembly function from a BinaryReader.
