c7c431f88e bx_instr_mem_data_access became completely obsolete with new stack optimization merged into SVN.
It already had limited usability before. With stack direct access optimization the callback won't be called for stack accesses as well.
See note by Brian Slechta:

=== Cut Hete ===
While using Bochs as a reference model for simulations, the simulator needs
information about what loads/stores are taking place with each instruction.
Presumably,  that  is  what  the BX_INSTR_MEM_DATA() instrumentation macros
cover (which is the place where our simulator hooks up).

The RETnear_xxx() functions call access_linear() directly, rather than call
read_virtual_xxx()  functions. This is a problem for code making use of the
BX_INSTR_MEM_DATA()   hook  because  it  does  not  get  called  for  these
instructions.  Should  this  be  changed along with some other instructions
that exhibit this?
=== Cut Hete ===

For Bryan's usage bx_instr_lin_access and bx_instr_phy_read/bx_instr_phy_write callbacks should be used.

e7a4a1bec8 surprisingly, opensuse 12.1 requre alignment check support in hardware so I can't disable it by default for all configurations.
but in case you want a few %% of extra emulation performance - it is still possible to disable it with configure option.
most guests I saw do not use it !

d4688e8b95 - Do not compile support for alignment check (#AC exception) by default
for CPU emulation performance reasons, the alignment check compilation
    still can be enabled using configure option --enable-alignment-check.

There is no software in the world which enable #AC exception checking, this
x86 feature is completely legacy but its emulation support costs up to 3-5%
emulation speed.

The checking for #AC exception enable still will be done, if

 CPL == 3, EFLAGS.AC = 1 and CR0.AM = 1

but the alignment check is not compiled in, the Bochs will PANIC with corresponding message.
You can press 'always continue' and ignore the PANIC, the simulation will continue as if alignment checking is not enabled.
