--- Comment #5 from Dominique d'Humieres <dominiq at lps dot ens.fr> --- Compiling the test with '-O3 -fno-align-jumps' gives GOTO costs totally 1.242 (s) SELECT CASE costs totally 1.253 (s) IF-Goto costs totally 1.507 (s) IF-noGoto costs totally 1.518 (s) IF-ELSE costs totally 1.514 (s) comparable with the timing for '-O1' (comment 4).
