None, extract_bit_field/store_bit_field are the right devices for this purpose.
What I have objections against is to have types that are less aligned t

The version of STRICT_ALIGNMENT with a mode argument is
SLOW_UNALIGNED_ACCESS (from GCC's perspective, there isn't much difference
between "unaligned accesses don't work at all"

Hi,
I'm trying to teach our expander how to deal with misaligned MEM_REFs
on strict alignment targets. We currently generate code which leads
to bus error signals due to misaligned accesses.
I admit my motivation is not any target in particular but simply being
able to produce misaligned MEM_REF
