I haven't explored it too deeply myself, but from what I understand, a
jump table is only generated if there are a large number of branches (over
50).Â If it's just a handful of branches, it simply subtracts values from
the input corresponding to the differences between the case labels, and
jumping to the next subtraction if there's a mismatch, or to the else block
if it goes negative.Â I'm not sure what it does for strings though.

I would need a clarification about the way the case statement is
translated into assembler by FPC. When the list of alternatives is
continous, does the compiler generate a jump table? And if yes, there is
some conditions for which a fall-through is performed anyway?
Thank you, Marco Borsari
