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.
