Given that

FAIL: gcc.c-torture/execute/bswap-1.c -O3 -g execution test
FAILs even in older GCC releases on powerpc64-linux and so does on the trunk,
I'd say there is some target bug with the bswapdi2 implementation.
Though, I can't really reproduce this (compiling both tests in a trunk cross to
powerpc64-linux, tried both -mcpu=power10 -O2 and just -m64 -O2, running on
cfarm121.cfarm.net, both bswap-1.c and builtin-bswapg-1.c pass).
