The problem is that GCC poisoning complains on prototypes too. qemu-kvm.h references CPUState and includes cpu.h, so with the latest changes all files that include qemu-kvm.h break, even if they don't require qemu-kvm.h. With this patch they instead get the opaque definition via hw/hw.h (which includes cpu-common.h), and qemu-kvm.h can avoid including cpu.h. Another example is the new apic.h file created by Blue Swirl. It references CPUState. It includes apic_get_irq_delivered, so I placed apic_set_irq_delivered there too. But apic_set_irq_delivered is used by i8259.c which is compiled once. There are other similar cases. Without something like this patch as a stopgap measure, you have to make everything compile again per-target which is a huge mess of conflicts. Paolo

There are lot of other ways to handle the need without resorting to per-target build.

CPUState use only in kvm_save/load_lapic. But these functions could just as easily take APICState* as their parameter and the need to pass CPUState is gone.

I'd rather things be compiled per-target than adding a bunch of crud everywhere. Wouldn't it be easier to split up qemu-kvm.h into qemu-kvm-cpu.h and add the later include where it's needed (which should be very few places)? Regards, Anthony Liguori > Paolo

Well, this patch in particular removes more lines than it adds. :-P Anyway---me too, given how hairy it's coming out.

I won't have time to do this if you prefer that, I guess I'll have to leave it to Marcelo and Avi. Paolo

This patch allows to unpoison CPUState and env in once-compiled files. To achieve this, it defines an opaque struct CPUState in cpu-common.h. This also requires tweaking the relationship between CPUState and CPUXYZState in target files. Unpoisoning env is needed because it is widely used as the name for CPUState arguments. This is anyway safe, because references to the global register variable will not creep into target-independent files. To this end, the patch rationalizes inclusions at the head of target-*/exec.h. All exec.h files now include cpu.h before defining the global register variable env, so that inclusions from machine-independent context will error out in cpu.h even before env is defined. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> --- This patch is helpful for qemu-kvm, because some of the changes there use CPUState in hw/* files that are now compiled only once. It can also be used to compile more files once-only, but I'm not doing that here. cpu-common.h | 3 +++ cpu-defs.h | 1 + hw/poison.h | 3 --- target-alpha/cpu.h | 4 +--- target-alpha/exec.h | 6 ++---- target-arm/cpu.h | 6 +++--- target-arm/exec.h | 5 ++--- target-cris/cpu.h | 6 +++--- target-cris/exec.h | 6 +++--- target-i386/cpu.h | 6 +++--- target-i386/exec.h | 7 ++----- target-m68k/cpu.h | 6 +++--- target-m68k/exec.h | 6 +++--- target-microblaze/cpu.h | 7 +++---- target-microblaze/exec.h | 6 +++--- target-mips/cpu.h | 5 +---- target-mips/exec.h | 6 ++---- target-ppc/cpu.h | 3 +-- target-ppc/exec.h | 2 -- target-s390x/cpu.h | 6 +++--- target-s390x/exec.h | 7 +++---- target-sh4/cpu.h | 6 +++--- target-sh4/exec.h | 5 ++--- target-sparc/cpu.h | 6 +++--- target-sparc/exec.h | 6 +++--- 25 files changed, 56 insertions(+), 74 deletions(-)
