Be interesting for others to try the below script!
I will be looking at "flx" to see if I can swap the compiler, i.e. an option
like
flx --cxx=g++
flx --cxx=clang++
so I can compile Felix generates C++ with different compilers.
Just so you know: MacBook Pro, OSX Snow Leopard.
~/felix>gcc --version
i686-apple-darwin10-gcc-4.2.1 (GCC) 4.2.1 (Apple Inc. build 5666) (dot 3)
~/felix>clang --version
clang version 3.3 (trunk 168409)
Target: x86_64-apple-darwin10.8.0
Thread model: posix
~/felix>ocamlopt -version
3.11.1
Bash Script, run from repository:
echo "C-clang"
clang -O1 -m64 speed/ack/c/ack.c -o clang-ack && ./clang-ack
echo "C-gcc"
gcc -O2 -m64 speed/ack/c/ack.c -o gcc-ack && ./gcc-ack
echo "Felix: clang"
flx -O1 -c --static -o flx-ack speed/ack/felix/test.flx && ./flx-ack
echo "Ocaml"
ocamlopt.opt -o ocaml-ack unix.cmxa speed/ack/ocaml/test.ml && ./ocaml-ack
Results:
~/felix>sh perf.sh
C-clang
Ack(3,13): 65533
7.585431
C-gcc
Ack(3,13): 65533
8.391670
Felix: clang
Ack(3,13): 65533
7.71534
Ocaml
Ack(3,13): 65533
6.965121
Ocaml wins, Felix is second (beating both gcc and clang).
And look at this:
C: gcc 4.2.1 -O1
Ack(3,13): 65533
25.048595
disgusting.
Results vary a bit between runs:
~/felix>sh perf.sh
C: clang 3.3 -O1
Ack(3,13): 65533
7.430569
C: clang 3.3 -O2
Ack(3,13): 65533
8.148011
C: gcc 4.2.1 -O1
Ack(3,13): 65533
27.203562
C: gcc 4.2.1 -O2
Ack(3,13): 65533
11.149214
Felix: clang -O1
Ack(3,13): 65533
7.94626
Ocaml 3.11.1
Ack(3,13): 65533
7.956184
I'm working on web pages to display results.
