--- Comment #3 from Dominique d'Humieres <dominiq at lps dot ens.fr> ---
I suspect that the code is not testing what it is expected to test. IMO the
lines
key = mod(n,10) + 1
should be replaced with
key = mod(i,10) + 1
With the change I get
GOTO costs totally 3.377 (s)
SELECT CASE costs totally 4.455 (s)
IF-Goto costs totally 1.553 (s)
IF-noGoto costs totally 1.572 (s)
IF-ELSE costs totally 1.547 (s)
GCC 4.8.5 is significantly slower
GOTO costs totally 6.594 (s)
SELECT CASE costs totally 7.215 (s)
IF-Goto costs totally 4.512 (s)
IF-noGoto costs totally 4.601 (s)
IF-ELSE costs totally 4.581 (s)
