I was planning to do that in the next revision of this series. BTW, I
guess the following in the arm linkage.h of kernel is useful too. Any
thoughts?
#define __ALIGN .align 0
#define __ALIGN_STR ".align 0"
arm allows unaligned instruction execution ? i would have thought it'd
require higher alignment than that. i don't think that'd be a good default
for everyone ...
Unaligned instruction execution - No. ARM instruction should be 4 byte
aligned and Thumb instruction should be 2 byte aligned.
Unaligned data access - to a certain extent yes and is programmable.
IIRC, access to 32 bit integer is possible at 2 byte boundary but not
at an odd address.
Yes, I was also a little puzzled by that one.
