unexpected failure for scc001

[Joachim Breitner]

Hi,

it seems that adding the oneShot annotation to the interface causes
scc001 to fail:


Actual prof output differs from expected:

*** unexpected failure for scc001(profasm)

Now after reading some of the code it seems that the output is
normalized considerably before comparing.

But I’m not fully sure what is being checked here. So things change: Is
that change a regression? An improvement? Or just an a wobble that
should not worry me?

Greetings,
Joachim
