...allow an apostrophe as a digit group separator in integers, a la C++). Perhaps there are some syntactic enhancements that would make .td files easier to read and write. Perhaps there are common portions of .td files that can be factored out to reduce future duplications, as with Automaton.td and SearchableTable.td. Perhaps there are common portions of TableGen backends that can be factored out to reduce future efforts, resulting in some general-purpose library methods. Perhaps there are new features in TableGen that, coupled with enhanced or new C++ files, would open up possibilities for using TableGen...

...e main requirement was to add a slot to the RecordVal class to hold the source location of the statement that defined the field. To make that easier to use, I added a third PrintFatalError() method that accepts a RecordVal and grabs the source location from it. To test these ideas, I worked on the SearchableTable backend. It now includes in every message at least the record location and often the field definition location. I also reworded some message to make them more consistent. I will submit a patch to Phabricator soon. The problem now is that every backend has to be modified to take advantage of these...

I'd like to store a tablegen generated enumeration in a record field/value. Clearly this enumeration isn't available yet so it seems that a code fragment should be the escape mechanism I need. Looking at the other backends for examples, I see things like [{ return Imm >= 0 && Imm < 64; }] // promising code Requires = [{ {} }];
