--- 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.
