I tried this experiment with both gcc-4.0.x and gcc-4.1.x, replacing the --with-target option with a --target option. In both cases, I see that code is being scheduled for an SB-1 cpu. I verified this by compiling a small testcase with -O2 -dS -fsched-verbose=2. This dumps some instruction scheduling info to stderr. This output has lines like this: ;; 14--> 23 $f0=$f12*$f0 :sb1_fp1 which proves that SB-1 scheduling info is being used. -- Jim Wilson, GNU Tools Support, http://www.specifix.com
