[Qemu-devel] [PATCH 0/4] introduce NEED_GLOBAL_ENV

[Paolo Bonzini <pbonzini@redhat.com>]

Let's start the cleanups from the feature required by Blue Swirl.
I also include here a baby step towards removing eminently TCG-related
stuff from cpu.h.

After this series, only a bunch of files will include exec-all.h,
instead of getting it indirectly from cpu.h.

Note that (as sworn in the previous submission) exec.h is only included
by files that need the global register variable (i.e. cpu-exec.c and
target-*/op_helper.c), and this is the same subset that gets
NEED_GLOBAL_ENV in this patchset.

i386 and sparc have functions declared in cpu.h that are in op_helper.c.
I checked that these do not need the global variable, but it would be
nice to cleanup those too.

Paolo Bonzini (4):
  remove unused stuff from */exec.h
  move cpu_pc_from_tb to target-*/exec.h
  remove exec-all.h inclusion from cpu.h
  require #define NEED_GLOBAL_ENV for files that need the global
    register variable
