I had a look, but there is nothing there that is related - eventually
a latent alignment bug was fixed in IVOpt.
Excellent. Thanks for digging into what really hap

I had a look, but there is nothing there that is related - eventually
a latent alignment bug was fixed in IVOpt. Note that the bswap phase
currently inserts unaligned accesses irrespectively of STRICT_ALIGNMENT

Looking at PR77308, one of the issues is that the bswap optimization
phase doesn't work on ARM. This is due to an odd check that uses
SLOW_UNALIGNED_ACCESS (which is always true on ARM). Since the testcase
in PR77308 generates much better code with
