Summary: We now have two sets of generated TableGen files, one for R600 and one for GCN, so each sub-target now has its own tables of instructions, registers, ISel patterns, etc. This should help reduce compile time since each sub-target now only has to consider information that is specific to itself. This will also help prevent the R600 sub-target from slowing down new features for GCN, like disassembler support, GlobalISel, etc. Reviewers: arsenm, nhaehnle, jvesely Reviewed By: arsenm Subscribers: MatzeB, kzhuravl, wdng, mgorny, yaxunl, dstuttard, tpr, t-tye, javed.absar, llvm-commits Differential Revision: https://reviews.llvm.org/D46365 llvm-svn: 335942
