Hmm, this looks target-specific. It may be bad RTL coming out of the
tree-ssa passes. I doubt I can reproduce it on another target, but
could you post a .i file?
If you can reproduce this with -fdisable-simple, then the problem may
not be in the gimplifier nor the tree optimizers.
If you can reproduce this with -fdisable-tree-ssa, then the problem is
in the tree optimizers.
If you can reproduce this with -fdisable-simple but it works with
mainline, then we have a bigger problem because -fdisable-simple
completely disables GIMPLE and the tree optimizers, resulting in a
compiler that should behave exactly like mainline.
Thanks. Diego.
