[avr-gcc-list] testsuite saga continues

[Paulo Marques]

Hi all,

I'm still trying to get the testsuite to pass all tests cleanly.

Yesterday I've done a patch to mark as unsupported tests that used the 
"double" type. This helps float-floor.c pass the test (as unsupported) 
but 538 tests (just in execute.exp) are also marked as unsupported 
because of this.

It seems like a bad trade-off, so I'll try to come up with a way to 
change just float-floor.c to "#ifdef" on the size of the double type, so 
that it doesn't fail, and we can keep all the other tests.

In the meantime, I tried to not mark "long long" as unsupported, with 
similar results.

Without "no_long_long" there are more 32 tests that fail, but less 556 
tests are marked as unsupported. Which means that 64 bit "long long"'s 
are mostly supported in fact.

The question is: are "long long"'s officially supported? Should we be 
running the tests that use them?

BTW: 64 bit long long is really hard for a 8 bit microcontroller. At 
least one of the tests (with -O0 optimization) was initially failing 
from timeout, which means that it was taking more than 500 million 
cycles to execute. Increasing the timeout to 2 billion cycles solved the 
problem, though.
