In some cases, the patch to fix the behaviour for some
architectures may-or-may-not-(but-this-has-to-be-proven)
hurt performance or something on other architectures
while retaining correctness. In these cases, always if
the language does not have #ifdef, but even sometimes if
it does, it’s better to use the one correct, slower on
some architectures, codepath than to over-optimise – for
example, see the recent discussion here about unaligned
data access on various architectures, where it was even‐
tually agreed to use the “safe” codepath everywhere, to
avoid UB and other pitfalls.
