示例1: HandleDLLImportAttr

// Attribute can be applied only to functions or variables.
FunctionDecl *FD = dyn_cast<FunctionDecl>(D);
if (!FD && !isa<VarDecl>(D)) {
// Apparently Visual C++ thinks it is okay to not emit a warning
// in this case, so only emit a warning when -fms-extensions is not
// specified.
if (!S.getLangOpts().MicrosoftExt)
S.Diag(Attr.getLoc(), diag::warn_attribute_wrong_decl_type)
<< Attr.getName() << 2 /*variable and function*/;

// Currently, the dllimport attribute is ignored for inlined functions.
// Warning is emitted.

return;
}
unsigned Index = Attr.getAttributeSpellingListIndex();
DLLImportAttr *NewAttr = S.mergeDLLImportAttr(D, Attr.getRange(), Index);
if (NewAttr)

}示例2: HandleDLLExportAttr
static void HandleDLLExportAttr(Decl *D, const AttributeList &Attr, Sema &S) {
// check the attribute arguments.
if (Attr.getNumArgs() != 0) {
S.Diag(Attr.getLoc(), diag::err_attribute_wrong_number_arguments) << 0;

// special about calling a force_align_arg_pointer function.
