I thought that these two were already solved by these patches:
https://reviews.llvm.org/D25923  - beamformer
https://reviews.llvm.org/D25924  - telecomm-fft

These 3 should have been fixed by this patch:

These are harder to modify to make them pass with contract on and off.
I recommend adding CFLAGS += "-ffp-contract=off"
