Okay.
Hmm, it doesn't apply cleanly.
The trunk version of simd_clone_create also contains: 'Fix ICE for SIMD
clones usage in LTO' (
https://gcc.gnu.org/ml/gcc-patches/2015-10/msg00434.html ), which adds
the 'in_other_partition' propagation in simd_clone_create.
That's also not a release regression (reproduces with 4.9.0 release, not
supported in 4.8), and still reproduces on 4.9 and 5 branches.
OK to backport 'Fix ICE for SIMD clones usage in LTO' to 4.9/5 branch?
Thanks,
