With the avrtest simulator, I observe the following problem with the -m option (max instruction count):
>avrtest var-expand2.exe -mmcu=avr51 -m 1019948
exit status: TIMEOUT
reason: instruction count limit reached
program: var-expand2.exe
exit address: 000318
total cycles: 1483103
>avrtest var-expand2.exe -mmcu=avr51 -m 1019949
[...avrtest hangs...]
So there is a barrier: for all -m values >= 1019949 avrtest hangs, for
-m <= 1019948 avrtest stops as desired.
I am using avrtest as of
http://winavr.cvs.sourceforge.net/viewvc/winavr/avrtest/
All this blocks my work on avr-gcc, because I use avrtest as simulator
to run regression tests. FYI, I attached the avr-elf32 executable
var-expand2.exe (as tar, because mailing list rejects .exe).
Is there a place that hosts updated versions of avrtest or is there a
site with more stable simulator that can run avr regression tests?
Thanks for any hints on that.
At current, I use the setup described in
http://lists.gnu.org/archive/html/avr-gcc-list/2009-09/msg00016.html
Besides that, I observed that my test results differ completely from
the results posted by Mike Stein in
http://gcc.gnu.org/ml/gcc-testresults
Unfortunately, his exact setup is not displayed, i.e. what simulator
(version) he uses and how he start the testsuite and what .exp he uses.
