Dear all,
I wanted to point out clues about why GCC manages the packed attribute
in this way.
The behavior is suspiciously similar to what the ARM RVDS compiler
(armcc) does with the __packed qualifier:

Dear Wolfgang Denk and Reinhard Meyer,
The compiler (4.4.1) generates the expected 32bit store instruction when using:
struct p {
int n;
} __attribute__ ((packed, aligned(4)));
In case of hardware registers, I have yet to see a case where this is not true.
Regards,
Francesco
