Remember to add all intrinsics here, in compiler/rustc_typeck/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
.
Trait method used to test whether a given pointer is associated with a type identifier.
Trait method used to load a function while testing if it is associated with a type identifier.
Trait method used to inject va_start
on the “spoofed” VaListImpl
in
Rust defined C-variadic functions.
