Hi All, One thing I believe also bothers someone else. Say we have the following code snippet: bits<32> insnEncoding; let insnEncoding{15-12} = 0b0100; Can we write the let expression with range list like this, with the same meaning? let insnEncoding{12-15} = 0b0100; I take a look on TGParser::ParseRangePiece (lib/TableGen/TGParser.cpp), seems the answer is YES. Can anyone confirm this? Thanks. Re...

Personally I find it pretty scary that we support the second form at all. It's mixing two different endiannesses with no real indication of which one will win. Tim.
