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

(

LLVMTypeRef

Ty

)

Obtain the context to which this type instance is associated.

char* LLVMPrintTypeToString

(

LLVMTypeRef

Val

)

Return a string representation of the type. Use LLVMDisposeMessage to free the string.

See Also

llvm::Type::print()

Definition at line 227 of file Core.cpp.

References llvm::raw_ostream::flush(), llvm::LibFunc::strdup, and llvm::unwrap().

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
