Hi,
Are you able to run this script with the latest simulavr? As soon as
I try to call either floating or fixed point routines, I am getting
errors:
rm: cannot remove `core_avr_dump.core': No such file or directory
Then if I delete the part in the script that tries to delete this file, I get:
...
<td>__addsf3 (1.234, 5.678)</td>
<td>7</td>
<td>7</td>
...
Which is obviously wrong. I tried running simulavr on the program
manually, and I get errors about address out of bounds. Maybe I need
an older simulavr? I am using cvs. It would be good to know if you
can run the script without errors and what simulavr version it is.
