Enumeration Type Documentation

◆ AlignmentSource

enum class clang::CIRGen::AlignmentSource

strong

The source of the alignment of an l-value; an expression of confidence in the alignment actually matching the estimate.

Enumerator
Decl	The l-value was an access to a declared entity or something equivalently strong, like the address of an array allocated by a language runtime.
AttributedType	The l-value was considered opaque, so the alignment was determined from a type, but that type was an explicitly-aligned typedef.
Type	The l-value was considered opaque, so the alignment was determined from a type.

◆ CleanupKind

enum clang::CIRGen::CleanupKind : unsigned

Enumerator
EHCleanup	Denotes a cleanup that should run when a scope is exited using exceptional control flow (a throw statement leading to stack unwinding, ).
NormalCleanup	Denotes a cleanup that should run when a scope is exited using normal control flow (falling off the end of the scope, return, goto, ...).

An unnamed bit-field wider than zero bits is not empty: it is storage the classifier reads like a named bit-field's. C++ record fields are never empty unless marked [[no_unique_address]], and that exception applies only to records, not arrays of records.
