Add 'not' to commands that are expected to fail. This is at least good documentation, but also opens the possibility of using pipefail. llvm-svn: 185652

// RUN: not %clang_cc1 -fsyntax-only -pedantic-errors %s 2>&1 | FileCheck %s --check-prefix=PRESUMED

Add -cc1 option -fno-diagnostics-use-presumed-location, a handy mode for working with preprocessed testcases. This causes source locations in diagnostics to point at the spelling location instead of the presumed location, while still keeping the semantic effects of the line directives (entering and leaving system-header mode, primarily). llvm-svn: 168004

Stop printing macro backtraces that don't help diagnostics. When displaying the macro backtrace, ignore some of the backtraces that do not provide extra information to the diagnostic. Typically, if the problem is entirely contained within a macro argument, the macro expansion is often not needed. Also take into account SourceRange's attached to the diagnostic when selecting which backtraces to ignore. Two previous test cases have also been updated. Patch by Zhengkai Wu, with minor formatting fixes. Differential Revision: http://reviews.llvm.org/D11778 llvm-svn: 244788
