Hi!
After seeing the config/t-slibgcc-fuchsia issue, I ran a dumb and slow
for f in `find . -type f`; do sz=`ls -l $f | awk '{print $5}'`; sz=`expr $sz /
2`; [ $sz = 0 ] && continue; if [ $sz -gt 16 ]; then dd if=$f of=/tmp/1 bs=1
count=16 2>/dev/null; dd if=$f of=/tmp/2 bs=1 skip=$sz count=16 2>/dev/null;
cmp -s /tmp/1 /tmp/2 || continue; fi; dd if=$f of=/tmp/1 bs=1 count=$sz
2>/dev/null; dd if=$f of=/tmp/2 bs=1 skip=$sz 2>/dev/null; cmp -s /tmp/1 /tmp/2
&& echo $f; done
command to discover similar cases of files that have both halves identical.

from which libgcc/config/t-slibgcc-fuchsia is fixed,
gcc/testsuite/gcc.c-torture/execute/ieee/pr29302-1.x is also a clear bug
that I've committed fix now and the rest most probably is intentional.
Committed to trunk as obvious.
