Author: jrose Date: Mon Jun 27 20:02:31 2016 New Revision: 273976 URL: http://llvm.org/viewvc/llvm-project?rev=273976&view=rev Log: Avoid accessing an invalid PresumedLoc.
DiagnosticNoteRenderer asserts trying to emit its "while building module Foo imported from bar.h:5" note when the presumed location of the import is invalid. This assertion was added in r267914, where most uses of 'getFilename' were updated to test 'isValid' instead. This one must have been missed. I can't come up with a test because this location is always valid in C-based code, but external clients that manually import modules (*cough*Swift*cough*) sometimes provide invalid SourceLocations. rdar://problem/26099576 http://reviews.llvm.org/D21111 Modified: cfe/trunk/lib/Frontend/DiagnosticRenderer.cpp Modified: cfe/trunk/lib/Frontend/DiagnosticRenderer.cpp URL: http://llvm.org/viewvc/llvm-project/cfe/trunk/lib/Frontend/DiagnosticRenderer.cpp?rev=273976&r1=273975&r2=273976&view=diff ============================================================================== --- cfe/trunk/lib/Frontend/DiagnosticRenderer.cpp (original) +++ cfe/trunk/lib/Frontend/DiagnosticRenderer.cpp Mon Jun 27 20:02:31 2016 @@ -618,7 +618,7 @@ DiagnosticNoteRenderer::emitBuildingModu // Generate a note indicating the include location.
