Hello
On the thread concerning GNU Octave in Japan, there was a report for jit
feature of octave-3.8.0 downloaded from http://mxeoctave.osuv.de/
octave-3.8.0-5, octave-3.8.1-rc3
Test
> a = 1; b = 1; tic; for i=1:1000; for j=1:1000; a = a + b; end; end; toc
Elapsed time is 1.5 seconds.
> jit_enable(1)
> a = 1; b = 1; tic; for i=1:1000; for j=1:1000; a = a + b; end; end; toc
(No response)
I have tested the same test on Ubuntu 12.04 LTS (32bit) on octave-3.8.0 built
by myself on my old notebook .
octave:1> a = 1; b = 1; tic; for i=1:1000; for j=1:1000; a = a + b; end; end;
toc
Elapsed time is 4.21553 seconds.
octave:2> jit_enable(1)
octave:3> a = 1; b = 1; tic; for i=1:1000; for j=1:1000; a = a + b; end; end;
toc
Elapsed time is 0.891052 seconds.
In this case jit feature worked correctly.
Have anyone met the same phenomena on mxe-build mingw octave ?
I would like confirm before filing bug report.
Regards
Tatsuro
