Dynamic C 10.72 makes RCM4000 run slow

Rabbit

However, same source code assembled with DC 10.11 runs normally fast.

All instructions run slower; eg.

with 10.72: LD a,(var1) uses .42uS time
with 10.11: LD a,(var1) uses .21uS time

and

with 10.72: LD DE,19 uses .30uS time
with 10.11: LD DE,19 uses .10uS time

CPU clock doubler shows enabled according to register GCDR
The peripheral CLK is running at 59MHz (normal apeed)

Thanks for any help.
Mike.

Did you check under DC10.70?

Can you send sample code that we can run to duplicate your issue?
