No change. I have arranged to get the MVME172 card back for an afternoon later
this week (11-Feb-2005). I will have a look then.

You can't just increase the alignment as that would break the ABI.

My copy of the 68060 user manual says that the MC68060ISP does contain an
emulation for unaligned CAS.

The Colfire operates the same as the x86 in that the cache/bus unit will
automagically handle una

Even the 68020 should already show slight improvement when using 4 byte
aligment due to the 32 bit data bus (the 68000/010 only have a 16 bit data
bus).
Adding an aligned attribute to the _Atomic_int type doesn't

Does this mean the instruction in question (cas) in atomicity.h cannot be used
on the 68060 if the stack can be aligned to a 2 byte boundary ?
Would a stack aligned this way cause a slow down if the call

--- Additional Comments From schwab at suse dot de 2004-11-03 22:25 ---
On the m68k the biggest alignment has traditionally only been 2 bytes
(inherited from the Sun compiler, AFAIK), and it's only overridden on NetBSD
(and previously on some configurations that are removed now) or when

Joel, you might want to talk to the m68k maintainers.
Take your pick:

m68k port (?) Jeff Law[EMAIL PROTECTED]

I emailed Chris privately. The stack is properly aligned. But his target is
not setup at the moment and he would have to build a special toolset without his
workwound/fix in place. He won't be able to do this
