Detailed Description

The collection of all-type qualifiers we support.

Clang supports five independent qualifiers:

C99: const, volatile, and restrict
MS: __unaligned
Embedded C (TR18037): address spaces
Objective C: the GC attributes (none, weak, or strong)

Member Enumeration Documentation

◆ anonymous enum

anonymous enum

Enumerator

MaxAddressSpace

The maximum supported address space number.

23 bits should be enough for anyone.

FastWidth

The width of the "fast" qualifier mask.

FastMask

The fast qualifier mask.

Definition at line 174 of file Type.h.

◆ ObjCLifetime

enum clang::Qualifiers::ObjCLifetime

Enumerator
OCL_None	There is no lifetime qualification on this type.
OCL_ExplicitNone	This object can be modified without requiring retains or releases.
OCL_Strong	Assigning into this object requires the old value to be released and the new value to be retained. The timing of the release of the old value is inexact: it may be moved to immediately after the last known point where the value is live.
OCL_Weak	Reading or writing from this object requires a barrier call.
OCL_Autoreleasing	Assigning into this object requires a lifetime extension.
