This passed bootstrap and regtesting with no regressions. Ok for trunk? This bug is also on the GCC 12 and GCC 11 release branches. Ok there too assuming testing is clean? I can wait to push the gcc12 backport until after the release. Peter If there is a homogeneous struct with float128 members, they should be copied to vector register save area. The current code incorrectly copies only the value of the first member, not increasing the pointer with each iteration. Fix this.
