It's even a goto in a switch statement, cause
switch(a)
{
case 0: ...
break;
case 1: ...
break;
default:
...
}
translates to something like this (6809 assembly to keep it simple)
LDA #a
ASLA
LDX #jump_table
JMP [A,X]
or
LDA #a
CPMA #0
BNE x1
...a...
BRA x3
x1: CMPA #1
BNE x2
...b...
BRA x3
x2:
...default...
x3:
As an assembly programmer I would prefer the first solution whereas
compilers (to my knowledge) tend to like the second one which is a 1:1
translation of a switch/case statement.
