Trait Implementations

impl Abi for X86_64SystemV

fn get_vmctx_ptr_param<'ctx>( &self, func_value: &FunctionValue<'ctx>, ) -> PointerValue<'ctx>

Given a function definition, retrieve the parameter that is the vmctx pointer.

fn func_type_to_llvm<'ctx>( &self, context: &'ctx Context, intrinsics: &Intrinsics<'ctx>, offsets: Option<&VMOffsets>, sig: &FuncSig, ) -> Result<(FunctionType<'ctx>, Vec<(Attribute, AttributeLoc)>), CompileError>

Given a wasm function type, produce an llvm function declaration.

fn args_to_call<'ctx>( &self, alloca_builder: &Builder<'ctx>, func_sig: &FuncSig, llvm_fn_ty: &FunctionType<'ctx>, ctx_ptr: PointerValue<'ctx>, values: &[BasicValueEnum<'ctx>], intrinsics: &Intrinsics<'ctx>, ) -> Result<Vec<BasicValueEnum<'ctx>>, CompileError>

Marshall wasm stack values into function parameters.

fn rets_from_call<'ctx>( &self, builder: &Builder<'ctx>, intrinsics: &Intrinsics<'ctx>, call_site: CallSiteValue<'ctx>, func_sig: &FuncSig, ) -> Result<Vec<BasicValueEnum<'ctx>>, CompileError>

Given a CallSite, extract the returned values and return them in a Vec.

fn is_sret(&self, func_sig: &FuncSig) -> Result<bool, CompileError>

Whether the llvm equivalent of this wasm function has an sret attribute.

fn pack_values_for_register_return<'ctx>( &self, intrinsics: &Intrinsics<'ctx>, builder: &Builder<'ctx>, values: &[BasicValueEnum<'ctx>], func_type: &FunctionType<'ctx>, ) -> Result<BasicValueEnum<'ctx>, CompileError>

Pack LLVM IR values representing individual wasm values into the return type for the function.
