Required methods

fn codegen_intrinsic_call(
    &mut self,
    instance: Instance<'tcx>,
    fn_abi: &FnAbi<'tcx, Ty<'tcx>>,
    args: &[OperandRef<'tcx, Self::Value>],
    llresult: Self::Value,
    span: Span
)

Remember to add all intrinsics here, in librustc_typeck/check/mod.rs, and in libcore/intrinsics.rs; if you need access to any llvm intrinsics, add them to librustc_codegen_llvm/context.rs

fn abort(&mut self)

fn assume(&mut self, val: Self::Value)

fn expect(&mut self, cond: Self::Value, expected: bool) -> Self::Value

fn sideeffect(&mut self)

fn va_start(&mut self, val: Self::Value) -> Self::Value

Trait method used to inject va_start on the "spoofed" VaListImpl in Rust defined C-variadic functions.

fn va_end(&mut self, val: Self::Value) -> Self::Value

Trait method used to inject va_end on the "spoofed" VaListImpl before Rust defined C-variadic functions return.
