This must be some strange new definition of "branchless" with which I'm not previously familiar; the generated code is full of branches, conditional or otherwise. I don't think invoking some other tool to put branches into your code qualifies you as branchless.
Have you compared your parser to simdjson-go? I haven't looked specifically at the go rewrite, but I hear it's decent.
I was very excited to do branch free coding to parse JSON, but really only handled the 'lexing' portion of the task in branch free fashion. Certainly more of the task could be done branch free, especially if you are working on SIMD or GPGPU.
