[antlr-interest] Reasonable performance expectations (v2.7.5)

[Bryan Ewbank]

So, I've got a compiler that takes a C-like language (around 25
tree-parsing passes) and does basic semantic analysis and some
optimizations (function inlining, constant propogation, etc).  I'm
using flex for the scanner, and C++ as my target language.

What does your gut tell you the expected execution time on a 10000
line input file would be?

I know this is a "shot in the dark" question, but I don't have much
intuition about how ANTLR performs.

Thanks,
