I am wondering whether they did analysize the Bigloo (Scheme) results:
[according to Manuel based on code by S. Gonzi; see comp.lang.scheme]
Compiler usr+usr
-----------------------------------------------------------+---------------
ocamlopt -unsafe -noassert -inline 2: 95.01s
bigloo -Obench -jvm (jdk1.3.1): 55.73s
java (jdk1.3.1): 52.53s
bigloo -Obench -copt "-ffast-math -fomit-frame-pointer -O3": 40.57s
gcc -ffast-math -fomit-frame-pointer -O3: 38.37s
Btw: the Stalin compiler produces code (note: common Scheme operators)
which runs faster than the C++ version even.
