Move the tcg related files into tcg/ subdirectory, which will make
the code more clean in qemu. Next step, we will base on those changes 
to disable tcg.

You should also move cpu-exec.c, cpu-exec-common.c and cputlb.c.

Also, feel free to squash everything in a single patch.
Thanks,

The LICENSE file in tcg directory contains this:

---------------------------------------------------------------------
All the files in this directory and subdirectories are released under
a BSD like license (see header in each file). No other license is
accepted.
---------------------------------------------------------------------

All source files have an explicit BSD license except tcg-runtime.h
which has none and aarch64 files which are licensed under GPL.  So we
are already not following the rule expressed in LICENSE.

tcg-runtime.c is BSD
tci.c is GPL
translate-all.[ch] are GPL
translate-common.c is GPL
cpu-exec.c cpu-exec-common.c cputlb.c are GPL

I guess the LICENSE file has become obsolete and so should be removed
(and Fabrice Bellard should perhaps be let know about that just in
case).

Thanks,

Laurent

We can change it to "The TCG backend files", followed by a list of
files.  But even then, aarch64 files are GPL...

  In fact, there are other two patchsets for those files. Since this patchset
  is only for moving TCG backend files into tcg/ subdirectory, i firstly upload
  this patchset.

  Let me explain my plan here, 

  In order to disable tcg, the first phase is to split some
  tcg code and separate those tcg related files into one
  directory. The next phase will disable tcg more easily and
  cleanly.

  In the first phase, there are three patchsets to
  deal with split code and separate the files.
  1) split the tcg exec code.
     a)split the tcg accelerators from accel.c file and re-name
       tcg accelerator to tcg-all.c, like kvm-all.c did.
     b)create one accel directory, which will include kvm,
       tcg and general exec files.
     c)move tcg exec files into ./accel/tcg directory.
  2) move tcg related backend files into tcg/ directory
     those files include translate-all.(ch), translate-common.c,
     tci.c and tcg-runtime.c.
  3) move kvm exec and exec.c file.
     a)move kvm related exec files into ./accel/kvm directory.
     b)move exec.c in ./accel directory.

  after 1) and 3) done, the file tree like below:
  accel/
  ├── accel.c
  ├── exec.c
  ├── kvm
  │   ├── kvm-all.c
  │   ├── kvm-stub.c
  │   ├── Makefile.objs
  │   └── trace-events
  ├── Makefile.objs
  └── tcg
      ├── cpu-exec.c
      ├── cpu-exec-common.c
      ├── cputlb.c
      ├── Makefile.objs
      ├── tcg-all.c
      └── trace-events
  
  please help me check whether this kind of arrange is suitable?

  for the tcg/ subdirectory, i will make those 6 patchset to one single patch. thanks!

Oh, I see now.  I think translate-all.[ch] and translate-common.c belong
in accel/tcg more than tcg/.
