...can provide me this information for all vector instructions. One way I can think of is, put this information along with the vector instruction description in the .td file. class vecInst<...,myInst s> : myInst<...> { myInst scalarVersion=s; } def AddV4 : vecInst<..., Add>; def SubV2 : vecInst<..., Sub>; ... def ORV4 : vecInst<..., OR>; Now, I can write a tablegen backend that can output a opcode->opcode map, which can be used by the pass. Is this and intended use case for Tablegen? Or, are tablegen backends supposed to be generic to all architecture backends?...

Manjunath, I asked this question recently, but instead of telling you to search the archive I'm going to take it as a chance to recall how to do it (because I'll do so anyway and even telling tablegen to use an enum for instructions is not as trivial to do as you might think : ) I wrote it up in the wiki at http://wiki.llvm.org/HowTo:_Add_arbitrary_properties_to_instructions Regards,

I want to add a set of "properties" to each instruction in my instruction set, and want to be able to query that in my machine-specific optimizations. My Insts.td file looks as follows : class InstProperty; def propX : InstProperty; def propY : InstProperty; def propZ : InstProperty; class myInst<..., list<InstProperty> props> : Instruction { ... ...
