Doing loops with TCG is a bad idea as it is very inefficient.
Did you read the code? There is no loop in TCG here, that's exactly
what I
was saying.
The labels are for conditionals only and for exiting the non-loop.
If you have a better suggestion, please say so as this is one of
the dyngen
ops that keep me from working on the conversion on my own system.
Going for a helper might be better for larger sequences of TCG ops;
Fabrice mentions a threshold of about 20 ops. And your replacement
is certainly larger than 20 ops :-) Plus given it uses brcond, it
would
prevent TCG liveness analysis from doing its job in the basic block
containing that instruction.
