-/* VERY BIG NOTE: Change of structure alignment for NetBSD/arm.
- There are consequences you should be aware of...
-
- Normally GCC/arm uses a structure alignment of 32 for compatibility
- with armcc. This means that structures are padded to a word
- boundary. However this causes problems with bugged NetBSD kernel
- code (possibly userland code as well - I have not checked every
- binary). The nature of this bugged code is to rely on sizeof()
- returning the correct size of various structures rounded to the
- nearest byte (SCSI and ether code are two examples, the vm system
- is another). This code breaks when the structure alignment is 32
- as sizeof() will report a word=rounded size. By changing the
- structure alignment to 8. GCC will conform to what is expected by
- NetBSD.
-
- This has several side effects that should be considered.
- 1. Structures will only be aligned to the size of the largest member.
- i.e. structures containing only bytes will be byte aligned.
- structures containing shorts will be half word aligned.
- structures containing ints will be word aligned.
-
- This means structures should be padded to a word boundary if
- alignment of 32 is required for byte structures etc.
-
- 2. A potential performance penalty may exist if strings are no longer
- word aligned. GCC will not be able to use word load/stores to copy
- short strings.
-
- This modification is not encouraged but with the present state of the
- NetBSD source tree it is currently the only solution that meets the
- requirements. */
