------- Comment #25 from victork at il dot ibm dot com 2007-08-13 06:42 -------
Yesterday, I've tried to check if mainline passes boostrap with vectorization
enabled on ppc32 using latest mainline. Since I don't have the access to ppc32
machine, I've tried to imitate in on ppc64 using the following config:
../gcc/configure --build=powerpc-suse-linux --with-cpu=default32
--prefix=/home/victork/mainline/usr.trunk.127373
--enable-languages=c,c++,fortran
Unfortuantely, this bootstrap failed as shown below:

Zdenek, David, did you try to test bootstrap with vectoriaztion enabled
recently? Can you give me an access to ppc32 to try my hand at it?
