Hi, I'd like to propose extending the supported syntax for AssemblerPredicates to allow sets of SubtargetFeatures to be listed, but where only one in the list has to be enabled for the predicate to be true. The condition string which forms a AssemblerPredicate already allows multiple features to be defined, separated by commas, and this means all of these features must be pr...

Hi All, I have faced decoding conflict of DisassemblerTables from TableGen. I have instructions with same encoding and different mnemonic among different architecture versions. I have used Predicates and AssemblerPredicates to distinguish them on Codegen and Assembler but it does not work on Disassembler. When I look at TableGen/FixedLenDecoderEmitter.cpp, once there is decoding conflict, tablegen does not generate table entry. I think it means even though there are predicates, it does not affect to the table entry. C...
