Add test case for nonnull attribute. Fix indexing bug. llvm-svn: 53882
2008-07-22 06:09:15 +08:00
// RUN: clang -fsyntax-only -verify %s
Tidy up sema processing of attribute "nonull": - warn about nonnull being applied to functions with no pointer arguments - continue processing argument list in the attribute when we encounter a non-pointer parameter being marked as nonnull - when no argument list is specified, only mark pointers as nonnull. This fixes PR 2732 and radar 6188814. llvm-svn: 55610
