Thanks Greg.  Would like to know what drove that decision.

Why are Zcmt opcodes using FP opcodes?  Is this a final decision by the committee?


This is what is proposed by the Code Size Reduction TG.  Tariq can comment on the reasons why.


Any "final decision" by the AR committee will only come when it reviews the final spec being proposed.  (But if I remember right, Tariq and the TG have good reasons for resorting to reusing some of the DP FP encoding space.  And I forget what related "working" feedback has come from other AR members to Tariq in the past.)


So, for now, this issue is in the TG's hands as part of developing the final spec.
