Compiling byte-based switches as lookup tables

[Reuben Thomas]

Is it possible to make GNU C compile a switch whose switch value is
byte-sized (e.g. a char in most implementations) into a lookup table without
a bounds check. I'm implementing a byte-code interpreter. Since I want to
write pure ANSI C, I can't use any GNU tricks like computed gotos.

I'm using egcs 2.91 on the Pentium.

(I'd appreciate replies CCed by email, as I don't usually read this group,
but understand entirely if you don't feel like it.)
