# Check whether memory alignment is required
#
# For some CPU types, unaligned memory access is either not supported at
# all (and so leads to a crash), requires a super-slow emulation via an
# exception handler, or just results in incorrect results.
# On the other hand, accessing data in a manner that works regardless of
# alignment can be a lot slower than regular access, so we don't want
# to use it if we don't have to.
#
# So we do the following: For CPU families where we know whether unaligned
# access is safe & fast, we enable / disable unaligned access accordingly.
# Otherwise, we just disable memory alignment.
#
# NOTE: In the past, for non-cross compiled builds, we would also run some code
# which would try to test whether unaligned access worked or not. But this test
# could not reliably determine whether unaligned access really worked in all
# situations (and across different implementations of the target CPU arch), nor
# whether it was fast (as opposed to slowly emulated by fault handlers). Hence,
# we do not use this approach anymore.
#
# NOTE: The only kinds of unaligned access we allow are for 2 byte and 4
# byte loads / stores. No promises are made for bigger sizes, such as 8
# or 16 byte loads, for which architectures may behave differently than
# for the smaller sizes.
