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.
thanks!
