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

LLVMPrintTypeToString()

char * LLVMPrintTypeToString

(

LLVMTypeRef

Val

)

Return a string representation of the type.

Use LLVMDisposeMessage to free the string.

LLVMTypeIsSized()

LLVMBool LLVMTypeIsSized

(

Ty

)

Whether the type has a known size.

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