class ParsedAttr

Declaration

class ParsedAttr : public AttributeCommonInfo, private TrailingObjects { /* full declaration omitted */ };

Description

ParsedAttr - Represents a syntactic attribute. For a GNU attribute, there are four forms of this construct: 1: __attribute__(( const )). ParmName/Args/NumArgs will all be unused. 2: __attribute__(( mode(byte) )). ParmName used, Args/NumArgs unused. 3: __attribute__(( format(printf, 1, 2) )). ParmName/Args/NumArgs all used. 4: __attribute__(( aligned(16) )). ParmName is unused, Args/Num used.

bool slidesFromDeclToDeclSpecLegacyBehavior()
    const

Description

Returns whether a [[]] attribute, if specified ahead of a declaration, should be applied to the decl-specifier-seq instead (i.e. whether it "slides" to the decl-specifier-seq). By the standard, attributes specified before the declaration always appertain to the declaration, but historically we have allowed some of these attributes to slide to the decl-specifier-seq, so we need to keep supporting this behavior. This may only be called if isStandardAttributeSyntax() returns true.
