[Bug go/63172] gccgo testcase cplx2.go execution provides incorrect answers on trunk for powerpc64, powerpc64le


https://gcc.gnu.org/bugzilla/show_bug.cgi?id=63172

--- Comment #3 from Dominik Vogt <vogt at linux dot vnet.ibm.com> ---
So the problem is that for some targets gcc's constant folding may yield a
different result for floating point calculations than the result if the
calculations were done on the target.  The attached test programs show this for
Go and C on s390, and maybe other platforms.
