Log: Experimental scanner: pass -b to re2c.
It seems to generate a bit faster scanner.
From re2c doc:
-b: Implies -s. Use bit vectors as well in the attempt to coax better code
out
of the compiler. Most useful for specifications with more than a few
keywords (e.g. for most programming languages).
-s: Generate nested ifs for some switches. Many compilers need this assist
to
generate better code.
