[llvm-dev] ERROR:Segmentation fault

[Dylan McKay via llvm-dev]

This is failing because in the file you attached to me you’re defining an
empty register class.

include "llvm/Target/Target.td"

def Abc : Target
{
}

class Reg<string n> : Register<n> {
  let Namespace = "SYMPL";
}

def R1 : Reg<"r1">;

def NOReg : RegisterClass<"SYMPL", [ i32 ], 32, (add R1)>;

Here’s what it looks like when you define a register ‘r1’ and add it to the
register class. I had to add a bunch of stuff at the top to get TableGen to
compile it on its own.

When I run llvm-tblgen -gen-register-info SYMPLRegisterInfo.td it succeeds.
