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 compiler/rustc_hir_analysis/src/check/mod.rs, and in library/core/src/intrinsics.rs; if you need access to any LLVM intrinsics, add them to compiler/rustc_codegen_llvm/src/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 type_test( &mut self, pointer: Self::Value, typeid: Self::Value ) -> Self::Value

Trait method used to test whether a given pointer is associated with a type identifier.

fn type_checked_load( &mut self, llvtable: Self::Value, vtable_byte_offset: u64, typeid: Self::Value ) -> Self::Value

Trait method used to load a function while testing if it is associated with a type identifier.

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.
