New Revision: 214375

URL: http://llvm.org/viewvc/llvm-project?rev=214375&view=rev
Log:
Don't fail tablegen immediately after failing to set a value.

Instead allow the variable to be declared, but don't attach an initializer. This allows more than a single error to be emitted before we exit.

Test case to follow soon in another patch.
