tokens cached during the non-cached lex, otherwise we are going to drop them. Fixes a bogus "_Pragma takes a parenthesized string literal" error when expanding consecutive _Pragmas in a macro argument. Part of rdar://11168596 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@153994 91177308-0d34-0410-b5e6-96231b3b80d8
2012-04-03Correct handling of _Pragma macro inside a macro argument.Argyrios Kyrtzidis
If we are pre-expanding a macro argument don't actually "activate" the pragma at that point, activate the pragma whenever we encounter it again in the token stream. This ensures that we will activate it in the correct location or that we will ignore it if it never enters the token stream, e.g: \#define EMPTY(x) \#define INACTIVE(x) EMPTY(x) INACTIVE(_Pragma("clang diagnostic ignored \"-Wconversion\"")) This also fixes the crash in rdar://11168596. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@153959 91177308-0d34-0410-b5e6-96231b3b80d8
