efac8da4cfa49799d5fdbc9d10b0e9f9a53ff6c8 07-Apr-2013 Benjamin Kramer <benny.kra@googlemail.com> Sema: Don't crash when trying to emit a warning for a duplicate value in an invalid enum.

Fixes PR15693. A null check on a pointer returned from cast<> is a very dubious
construct, do we have a checker for this somewhere?

a734a0eab27678262bea07786b6ff30d5c7a6356 22-Dec-2012 Ted Kremenek <kremenek@apple.com> Add back -Wduplicate-enum which I mistakenly removed.

This was removed with -Wunique-enum, which is still removed. The
corresponding thread on cfe-comments for that warning is here:


If we get specific user feedback for -Wduplicate-enum we can evaluate
whether or not to keep it.

43f8c40b05482894d94a8779a5ccd0f9a35420f3 18-Sep-2012 Ted Kremenek <kremenek@apple.com> Per discussion on cfe-dev, remove -Wunique-enums entirely. There
is no compelling argument that this is a generally useful warning,
and imposes a strong stylistic argument on code beyond what it was
intended to find warnings in.

9f6419f96d6cad3f7bd39f444cfc784ccbbdcd65 30-Aug-2012 Richard Trieu <rtrieu@google.com> Add -Wduplicate-enum warning. Clang will emit this warning when an implicitly
initiated enum constant has the same value as another enum constant.

For instance:
enum test { A, B, C = -1, D, E = 1 };
Clang will warn that:
A and D both have value 0
B and E both have value 1

A few exceptions are made to keep the noise down. Enum constants which are
initialized to another enum constant, or an enum constant plus or minus 1 will
not trigger this warning. Also, anonymous enums are not checked.
