Could we expose predicates defined in the target InstrInfo.td file to the MachineVerifier? We use BuildMI() to create many instructions after ISEL, but the predicates are not being checked at this point. Thus, I could forget to check the target and build an instruction that is illegal for a specific configuration. In such a case it would be nice if the MachineVerifier could detect this for me.

What is the purpose of tablegen created files for fast-isel? If I make the following change to Makefile in lib/Target/Mips BUILT_SOURCES = MipsGenRegisterInfo.inc MipsGenInstrInfo.inc \ MipsGenAsmWriter.inc MipsGenCodeEmitter.inc \ MipsGenDAGISel.inc MipsGenCallingConv.inc \ - MipsGenSubtargetInfo.inc MipsGenMCCodeEmitter.inc \ +
