Hello all,
I've been using 2.4.0 successfully for a while now. I've downloaded 2.5.0-rc1
and was able to compile it and use it to build GMP-ECM with no problems (it even
makes GMP-ECM a tiny bit faster). However, I wanted to run the tuneup program
to try to optimize mpir for my system. I read in the manual that I should be
able to:
cd tune
make tuneup
./tuneup
However, "make tuneup" gives a lot strange error messages. For some strange
reason, in order to build tuneup on my computer, I need to do:
cd tune
make tuneup.exe
./tuneup
This creates tuneup.exe just fine.
Then, when I run tuneup.exe, the program seemingly hangs at:
#define HGCD_THRESHOLD 30
#define GCD_DC_THRESHOLD
It turns out that it is not hanging, it gets to line 2374 of speed.h and
(somehow) a very large number is copied from s->reps into i. Then, since i is
so large, the following "do" loop just keeps going and going.
It took a while to track down the problem to this part of the code, and I'm not
quite sure:
1) how s->reps gets set
2) why s->reps is so large during this function and not any others
Has anyone come across this problem before? Is there a simple solution? Would
anyone need more information to help me figure this out? If so, what would you
like to know?
My environment is as follows:
Windows XP Pro x64 SP2, Msys shell, Mingw64 compiler, MPIR 2.4.0 and/or
MPIR-2.5.0-rc1.
Any pointers or suggestions on how to proceed would be much appreciated. Thanks
for your time.
-David C.
