I dont think thats the case. It always generates the call to __floatdidf At -O1 and below it is called and > still produces incorrect results :-( Oh well, I give up for now. > All I have to test is qemu running OE/ppc603e. So i tried this test on qemu/uclibc and it seems to work for me at O1/O2/O3 using gcc 4.4.4 and minimal-uclibc distro. I would also try with eglibc but I need to build it. > Vitus > > -- > Vitus Jensen, Hannover, Germany, Universe (current) > pgp public key available from keyservers > > _______________________________________________ > Openembedded-devel mailing list > [email protected] > http://lists.linuxtogo.org/cgi-bin/mailman/listinfo/openembedded-devel > _______________________________________________ Openembedded-devel mailing list [email protected] http://lists.linuxtogo.org/cgi-bin/mailman/listinfo/openembedded-devel
