I have tried this, reverting the revision #192687 would fix this issue. But as the comment of the patch specifies "In big-endian mode, modes greater than word size (i.e. DFmode) are stored in VFP registers in little-endian order. We can't describe that accurately to GCC, so avoid taking subregs of such values.". Reverting the patch would adversely affect the big-endian toolchain. Hence, I assume that we should have an alternate fix.
