New Revision: 368718
URL: http://llvm.org/viewvc/llvm-project?rev=368718&view=rev
Log:
[Dwarf] Complete the list of type tags.
An incorrect verification error revealed that the list of type tags was
incomplete. This patch adds the missing types by adding a tag kind to
the Dwarf.def file, which is used by the `isType` function.
A test was added for the original verification error.
