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

◆ LLVMDumpType()

void LLVMDumpType ( LLVMTypeRef  Val)

Dump a representation of a type to stderr.

See also
llvm::Type::dump()

Definition at line 363 of file Core.cpp.

References llvm::unwrap().

◆ LLVMGetTypeContext()

LLVMContextRef LLVMGetTypeContext ( LLVMTypeRef  Ty)

Obtain the context to which this type instance is associated.

See also
llvm::Type::getContext()

Definition at line 358 of file Core.cpp.

References llvm::unwrap(), and llvm::wrap().

◆ LLVMGetTypeKind()

LLVMTypeKind LLVMGetTypeKind ( LLVMTypeRef  Ty)

◆ LLVMPrintTypeToString()

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 368 of file Core.cpp.

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

◆ LLVMTypeIsSized()

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
