search for: rangelist

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

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.

If object::ObjectFile would contain fragmented sections then we need a solution of how that could work. One possibility is to create...

Yup. (as we've touched on before, we don't use aranges at Google - instead relying on CU's ranges which are just a little more expensive to retrieve - but no need to duplicate the data in both places - if consumers really find the aranges worthwhile to avoid parsing a few attributes o...
