enabling turbofan doesn't output hydrogen.cfg

[tusharmath]

Hi @mraleph following your directions as explained here — http://mrale.ph/irhydra/2/# I am facing this issue. Setup

Node: v7.0.0
V8:   5.4.500.36
----------------

Command

node \
--turbo
--trace-hydrogen \
--trace-phase=Z \
--trace-deopt \
--code-comments \
--hydrogen-track-positions \
--redirect-code-traces \
--redirect-code-traces-to=code.asm \
profile.js

Expected Creates hydrogen.cfg and code.asm files

Actual only code.asm file is created.

IRHydra does not support TurboFan (it uses an entirely different IR form).

You can use turbolizer to view TF IR. (Though I don't think it supports deoptimization matching similar to IRHydra).

There are currently no plans to support TurboFan in IRHydra.
