Detailed Description

Types represent the type of a value.

Types are associated with a context instance. The context internally deduplicates types so there is only 1 instance of a specific type alive at a time. In other words, a unique type is shared among all consumers within a context.

A Type in the C API corresponds to llvm::Type.

Types have the following hierarchy:

types: integer type real type function type sequence types: array type pointer type vector type void type label type opaque type

Function Documentation

LLVMContextRef LLVMGetTypeContext ( LLVMTypeRef Ty )

Obtain the context to which this type instance is associated.

LLVMTypeKind LLVMGetTypeKind ( LLVMTypeRef Ty )

Obtain the enumerated type of a Type instance.

LLVMBool LLVMTypeIsSized ( LLVMTypeRef Ty )

Whether the type has a known size.

Things that don't have a size are abstract types, labels, and void.a
