You can still do

    d8 --trace-turbo                        \
       --trace-deopt                        \
       --code-comments                      \
       --redirect-code-traces               \
       --redirect-code-traces-to=code.asm   \
       --print-opt-code                     \
       your-file.js

and load resulting turbo.cfg and code.asm into IRHydra.

However most of the important features (like source and deopt-to-ir mapping) are broken.

I used to repair things in my free time - but I don't think I want to do it anymore.
