I'm trying to follow-along on page 89 of Robert Morgan's "Building an
Optimizing Compiler" where he is describing the algorithm he has for
detecting single- and multi-entry loops.
He's being a little loose with the data types there - freely mixing
"LoopNodes" and "Blocks", and then I see his pseudo-code references
something called 'Z', in this line:
LoopEntry(X) = Z;
but - Z doesn't appear to be defined anywhere..
This makes me think I have an older edition - but I couldn't find any
newer printing, and I couldn't find an errata anywhere.
Does anyone pointers to an errata? Does anyone have contact info for
- Thanks! -

p.s. I checked on Amazon - the book is going for more than $450 these
days! Maybe I should just hold on to my two copies and use them for
my retirement one day!
