Leon3 GR-XC3S-1500 FPU problem

[Luis Mollinedo Herrera]

Hello,

We are working with a GR-XC3S-1500 board
(http://www.gaisler.com/cms/index.php?option=com_content&id=74&Itemid=63&limit=9\
&limitstart=153) with the GRLIB-1.0.22 + GRFPU-Lite configuration bitfile
(http://gaisler.com/products/boards/gr-xc3s-1500_bitfiles.zip).

The dhrystone and whetstone benchmarks works, but the problem starts with our
own code written in C and compiled with the RTEMS cross-compiler. With the next
compilation options:

"sparc-rtems-gcc -O2 -mv8 -mcpu=v8 -mhard-float *.c GNC_SW_nRT -I . -lm"

And with the RTEMS_FLOATING_POINT attribute
(http://www.rtems.com/wiki/index.php/Floating_Point_Support) we can perform
floating point operations included in the main file (GNC_SW_nRT.c), but the
floating point operations stored in secondary files does not work, and the
program finish without any warning or error message.

With the LEON3 configuration bitfile without hard FPU, and the -msoft-float
compilation option, the program works perfectly (very slow, but it works).

Could someone help us with this problem?

Thanks in advance.

Best regards,
Luis Mollinedo
