It's actually quite instructive to look through these goto
statements.
About 60% are in the finite state machine that is part of the
SPITBOL pattern matching unit. I have always felt that gotos
are a very natural representation of the arcs of a finite
state machine, and I invite people to look at the code of
g-spipat.adb to see if you agree :-)
Another section are for the finite state machine in the scanner.
Another big bunch are continue gotos. Ada lacks a continue
statement, and thus this facility must be simulated with a goto
as in
loop
if ... then goto Continue;
<<Continue>> null;
end loop;
This is actually quite a structured use of goto
There are only about 8 other instances of gotos in the
several hundred thousand lines of sources.
