Update tests to use %clang instead of 'clang', and forcibly disable use of ' clang ' or ' clang -cc1 ' or ' clang-cc ' in test lines (by substituting them to garbage). llvm-svn: 91460

// RUN: %clang -verify -pedantic %s -fsyntax-only
attempt to fix windows testers, which generate #line by default. llvm-svn: 131882

// RUN: %clang_cc1 -E %s | FileCheck %s
Fix #pragma GCC system_header by making it insert a virtual linemarker into the file at the point of the pragma. This allows clang to know that all sourcelocations after the pragma are in a system header. llvm-svn: 73376

// rdar://6899937
#include "pragma_sysheader.h"
Invoke the FileChanged callback before pushing the linemarker for a system header. Getting it in the wrong order generated incorrect line markers in -E mode. In the testcase from PR9861 we used to generate: # 1 "test.c" 2 # 1 "./foobar.h" 1 # 0 "./foobar.h" # 0 "./foobar.h" 3 # 2 "test.c" 2 now we properly produce: # 1 "test.c" 2 # 1 "./foobar.h" 1 # 1 "./foobar.h" 3 # 2 "test.c" 2 This fixes PR9861. llvm-svn: 131871
