The last sentence is unprecise, this would rather be: "Do not ca

There is a further subtlety in the second temp allocation when the expression
doesn't use the alias set of its type. In that case, we cannot pass the type
to set_mem_attributes. In fact, since assign_stack_temp_for_type already
calls the appropriate set_mem_* r

Hi,
when testing a patch of mine on sparc64-linux, I came across an Ada
bootstrap failure due to a structure DECL which was marked addressable
but had a register DECL_RTL (and therefore mem_ref_refers_to_non_mem_p
failed to trigger on it).
Mode of the structure was TI (16 bytes int) and it was mi
