Jakob, One more question. You had suggested 'ValueCols' as of type list<list<string> >. Does the TableGen know how to extract it? It appears to me that we may have to add support for that.

Hal, that’s a good point. There are more manually-maintained tables in the X86 backend that should probably be tablegened: the memory-folding tables and ReplaceableInstrs, to name a couple. If you have ideas on how to get these auto-generated, please let us know.

Hi Everyone, After some more thoughts to the Jacob's suggestion of using multiclasses for Opcode mapping, this is what I have come up with. Please take a look at the design below and let me know if you have any suggestions/questions. I have tried to keep the design target independent so that other targets could benefit from it. 1) The idea is to add 3 new classes into

Hi all, Imagine I have a matrix and the first colum is a list that repeats the same names, I want to sum the second column on each unique name on first column. Imagine this: Pepe 2 Pepe 3 Pepe 4 Jose 2 Jose 5 Manuel 4 Manuel 2 I want to make a new matrix that calculates and recognizes that there are 3 different names ans sum second column. But a priori I don´t know the list of the different

Hello LLVM, My target has a complex relaxation hierarchy. Perhaps a modest TableGen extension would help consolidate most of the work involved in choosing a relaxed opcode. I also notice the x86 relaxation code with a comment wondering if TableGen could improve life. Does the following outline sound interesting? 1) Add a new field of type 'Instruction' to the Instruction class called
