Bug ID: 35959
Summary: print warnings normally in /fallback mode
Product: clang
Version: trunk
Hardware: PC
OS: Windows NT
Status: NEW
Severity: enhancement
Priority: P
Component: Driver
Assignee: unassignedclangb...@nondot.org
Reporter: tras...@gmail.com
CC: llvm-bugs@lists.llvm.org
clang prints warning(clang) in fallback mode so MSBuild does not fail the build
because of errors printed by clang. But actually warnings could and should be
printed normally (so MSBuild/VS picks them up) as I still want to benefit from
clang's rich diagnostics even if it fails at some point.
Proof-of-concept:
Index: TextDiagnostic.cpp

// makes it more clear whether a message is coming from clang or cl.exe,
// and it prevents MSBuild from concluding that the build failed just
because
// there is an "error:" in the output.
