Configuration:
--target=armv7a-none-eabihf -march=v7-a -mthumb -mfloat-abi=hard -mfpu=neon -O3
In vectorize.c:
[vectorize.zip](https://github.com/llvm/llvm-project/files/13729421/vectorize.zip)
var_27 will be set to '1', which is not correct.
The reason is that in BasicBlock for.cond.for.cond.cleanup_crit_edge (pred is middle.block) the arr_14 array is overindexed.
I think that the problem is that tail-fold by masking happens, even though the invariant is used outside of the loop.
