findBlockLocations()

void findBlockLocations ( CFG * CFGraph, const PostOrderCFGView * SortedGraph, std::vector< CFGBlockInfo > & BlockInfo )

static

Find the appropriate source locations to use when producing diagnostics for each block in the CFG.

getStaticBooleanValue()

bool getStaticBooleanValue ( Expr * E, bool & TCond )

getValueDecl()

const ValueDecl * getValueDecl ( const Expr * Exp )

static

Gets the value decl pointer from DeclRefExprs or MemberExprs.

isCallbackParam()

bool isCallbackParam ( const ParmVarDecl * Param )

static

True if capability attributes on Param describe the function reached through it rather than the argument bound to it.

Sema accepts capability attributes on a parameter for two unrelated purposes: a scoped-lockable parameter, where the attributes describe the locks the passed scope object holds, and a parameter naming a function to call – a function pointer or a function reference – where they describe the requirements of the function called through it.
