Rafael Espindola	925213b0fa	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	2013-07-04 16:16:58 +00:00
Richard Smith	a8105bc9ce	C++11 generalized constant expressions: implement checking and diagnostics for ... pointer-arithmetic-related undefined behavior and unspecified results. We continue to fold such values, but now notice they aren't constant expressions. llvm-svn: 147659	2012-01-06 16:39:00 +00:00
Richard Smith	f6f003af6a	C++11 constexpr: Add note stacks containing backtraces if constant evaluation ... fails within a call to a constexpr function. Add -fconstexpr-backtrace-limit argument to driver and frontend, to control the maximum number of notes so produced (default 10). Fix APValue printing to be able to pretty-print all APValue types, and move the testing for this functionality from a unittest to a -verify test now that it's visible in clang's output. llvm-svn: 146749	2011-12-16 19:06:07 +00:00
