Hi list
Thinking more about the alignment problems on arm and elsewhere, I was
wondering how hard it would be to implement something like gcc's
-Wcast-align. Here's a description from the man page:
Warn whenever a pointer is cast such that the required alignment of the
target is increased. For example, warn if a "char *" is cast to an "int
*" on machines where integers can only be accessed at two- or four-byte
boundaries.
This would really help to catch problematic code before things get out
of hand and you have to wait for segfault/sigbus before you know where
the problems are.
