[diagtool] Write to llvm::outs() by default instead of llvm::errs() llvm-svn: 158954
2012-06-22 08:33:20 +08:00
// RUN: diagtool show-enabled %s | FileCheck %s
[diagtool] Re-add show-enabled, minimizing the code pulled in from Frontend. Now correctly builds with both GNU make and CMake. llvm-svn: 157932

//
// This shows warnings which are on by default.
// We just check a few to make sure it's doing something sensible.

Add warning flag -Winvalid-pp-token for preprocessing-tokens which have undefined behaviour, and move the diagnostic for '' from an Error into an ExtWarn in this group. This is important for some users of the preprocessor, and is necessary for gcc compatibility. llvm-svn: 159335
