Re: [avr-libc-dev] calculating benchmarks

[Sean D'Epagnier]

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.
