Module rustc_codegen_llvm::base

Codegen the completed AST to the LLVM IR.

Some functions here, such as codegen_block and codegen_expr, return a value -- the result of the codegen to LLVM -- while others, such as codegen_fn and mono_item, are called only for the side effect of adding a particular definition to the LLVM IR output we're producing.

Hopefully useful general knowledge about codegen:

• There's no way to find out the Ty type of a Value. Doing so would be "trying to get the eggs out of an omelette" (credit: pcwalton). You can, instead, find out its llvm::Type by calling val_ty, but one llvm::Type corresponds to many Tys; for instance, tup(int, int, int) and rec(x=int, y=int, z=int) will have the same llvm::Type.
