Description
I'd like to concatenate the signal src<63> 63 times to make a single 64-bit field "top". The response time of this code processing is too high... More than 2-3 minutes. The example follows.
top = src<63>::src<63>::src<63>::src<63>::src<63>::src<63>::src<63>::src<63>::
src<63>::src<63>::src<63>::src<63>::src<63>::src<63>::src<63>::src<63>::
src<63>::src<63>::src<63>::src<63>::src<63>::src<63>::src<63>::src<63>::
src<63>::src<63>::src<63>::src<63>::src<63>::src<63>::src<63>::src<63>::
src<63>::src<63>::src<63>::src<63>::src<63>::src<63>::src<63>::src<63>::
src<63>::src<63>::src<63>::src<63>::src<63>::src<63>::src<63>::src<63>::
src<63>::src<63>::src<63>::src<63>::src<63>::src<63>::src<63>::src<63>::
src<63>::src<63>::src<63>::src<63>::src<63>::src<63>::src<63>::src<63>;

Can be reproduced even with 24-times concatenation. Parsing tree gets too big (number of possible states increasing) and this significantly slows down parsing. The issue is related to ANTLR and parsing grammar. Need to think how to optimize it.

That's funny :).
locationExpr
: locationVal (DOUBLE_COLON^ locationExpr)*
;
replaced with
locationExpr
: locationVal (DOUBLE_COLON^ locationExpr)?
