do not hide clang stderr output during a test I don't know why this fails on the buildbot. llvm-svn: 207808 2014-05-02 06:40:00 +08:00			`// RUN: %clang -E -frewrite-includes %s -I%S/Inputs/ \| %clang -Wall -Wunused-macros -x c -c - 2>&1 \| tee %t.1`
			`// RUN: %clang -I%S/Inputs/ -Wall -Wunused-macros -c %s 2>&1 \| tee %t.2`
use 'diff' rather than 'cmp -s' in a test That's what all tests use, no idea where I got the latter from. llvm-svn: 207797 2014-05-02 05:36:08 +08:00			`// RUN: diff %t.1 %t.2`
write a line marker right before adding included file Enclosing the original #include directive inside #if 0 adds lines, so warning/errors messages would have the line number off in "In file included from <file>:<line>:", so add line marker to fix this. llvm-svn: 207795 2014-05-02 05:11:57 +08:00			`// expected-no-diagnostics`
			`// REQUIRES: shell`

			`#include "rewrite-includes-messages.h"`
			`#define UNUSED_MACRO`
