Author: djasper Date: Wed May 3 06:27:34 2017 New Revision: 302012 URL: http://llvm.org/viewvc/llvm-project?rev=302012&view=rev Log: Undo turning ExtBehavior into a bitfield.
This produces warnings that I can't explain in a GCC build: In file included from ../tools/clang/include/clang/Lex/LexDiagnostic.h:13:0, from /usr/local/google/home/djasper/llvm/tools/clang/lib/Lex/PTHLexer.cpp:19: ../tools/clang/include/clang/Basic/Diagnostic.h:219:34: warning: ‘clang::DiagnosticsEngine::DiagState::ExtBehavior’ is too small to hold all values of ‘enum class clang::diag::Severity’ [enabled by default] diag::Severity ExtBehavior : 4; // Map extensions to warnings or errors? ^ While I don't think this warning makes sense, I'd like to get this back to being warning-free. This only seems to trigger for "enum class".
