      build: simplify and fix fix-obj-vars · 2a8e6c7a
      由 Paolo Bonzini 提交于 
      fix-obj-vars has the undesired side effect of breaking -cflags
-objs and -libs variables in the toplevel Makefile.objs.  The
variables in the toplevel Makefile.objs do not need any fix,
so fix-obj-vars need not do anything.

Since we are touching it, remove the now unnecessary $(if)
in the callers.

      module: implement module loading · e26110cf
      由 Fam Zheng 提交于 
      This patch adds loading, stamp checking and initialization of modules.

The init function of dynamic module is no longer directly called as
__attribute__((constructor)) in static linked version, it is called
only after passed the checking of presense of stamp symbol:

    qemu_stamp_$RELEASEHASH

where $RELEASEHASH is generated by hashing version strings and content
of configure script.

With this, modules built from a different tree/version/configure will
not be loaded.

The module loading code requires gmodule-2.0.

Modules are searched under
 - CONFIG_MODDIR
 - executable folder (to allow running qemu-{img,io} in the build
   directory)
 - ../ of executable folder (to allow running system emulator in the
   build directory)

Modules are linked under their subdir respectively, then copied to top
level of build directory for above convinience, e.g.:
    $(BUILD_DIR)/block/curl.so -> $(BUILD_DIR)/block-curl.so

      rules.mak: introduce DSO rules · 17969268
      由 Fam Zheng 提交于 
      Add necessary rules and flags for shared object generation.
The new rules introduced here are:

1) %.o in $(common-obj-m) is compiled to %.o, then linked to %.so.

2) %.mo in $(common-obj-m) is the placeholder for %.so for pattern
matching in Makefile. It's linked to "-shared" with all its dependencies
(multiple *.o) as input. Which means the list of depended objects must
be specified in each sub-Makefile.objs:

    foo.mo-objs := bar.o baz.o qux.o

in the same style with foo.o-cflags and foo.o-libs. The objects here
will be prefixed with "$(obj)/" if it's a subdirectory Makefile.objs.

3) For all files ending up in %.so, the following is added automatically:

    foo.o-cflags += -fPIC -DBUILD_DSO

Also introduce --enable-modules in configure, the option will enable
support of shared object build. Otherwise objects are static linked to
executables.

      rules.mak: allow per object cflags and libs · 5c0d52bc
      由 Fam Zheng 提交于 
      Adds extract-libs in LINK to expand any "per object libs", the syntax to define
such a libs options is like:

        foo.o-libs := $(CURL_LIBS)

in block/Makefile.objs.

Similarly,

        foo.o-cflags := $(FOO_CFLAGS)

is also supported.

"foo.o" must be listed in a nested var (e.g. common-obj-y) to make the
option variables effective.

      rules.mak: fix $(obj) to a real relative path · ba1183da
      由 Fam Zheng 提交于 
      Makefile.target includes rule.mak and unnested common-obj-y, then prefix
them with '../', this will ignore object specific QEMU_CFLAGS in subdir
Makefile.objs:

    $(obj)/curl.o: QEMU_CFLAGS += $(CURL_CFLAGS)

Because $(obj) here is './block', instead of '../block'. This doesn't
hurt compiling because we basically build all .o from top Makefile,
before entering Makefile.target, but it will affact arriving per-object
libs support.

The starting point of $(obj) is passed in as argument of unnest-vars, as
well as nested variables, so that different Makefiles can pass in a
right value.

      win32: fix compilation again · fba90ac1
      由 Paolo Bonzini 提交于 
      While commit c02817e5 fixed compilation
without an installed libtool, moving the dependencies to rules.mak does
not work because the version-*-y variables are not defined yet.  Building
in a clean tree thus fails.

Revert the commit and remove the dummy /bin/false assignment to LIBTOOL.
This makes the build work, at the price of slightly worse errors when
there are Makefile bugs.

      rules.mk: Fix build breakage · 7e7da8e3
      由 Dunrong Huang 提交于 
      The following error occurs when building dtc module:

        CHK version_gen.h
         CC libfdt/fdt.o
cc1: error: dtc: No such file or directory [-Werror]
cc1: all warnings being treated as errors
make[1]: *** [libfdt/fdt.o] Error 1
make: *** [subdir-dtc] Error 2

In rules.mak, "-I$(<D) -I$(@D)" was expanded to "-Idtc -I." when
building submodule dct. Due to the using of "-Wmissing-include-dirs,
a warning would be rarsed. To avoid it, add "-I$(<D) -I$(@D)" to
QEMU_INCLUDES instead of QEMU_CFLAGS so that QEMU_CFLAGS does not
contain the "-Idtc".

      Support using a different compiler for Objective-C files · 3c4a4d0d
      由 Peter Maydell 提交于 
      MacOSX 10.8 ("Mountain Lion") requires us to compile our one
Objective-C source file with clang even if the rest of QEMU
requires a real gcc, because the system headers we use make
use of Apple's "Blocks" extension to C/ObjC, and mainline
gcc doesn't support that. Since we only need to use a true
gcc for the parts of QEMU that use the fixed-register
env variable, we can simply use clang to build the ObjC
file: it will link to the gcc-built objects with no problems.

Add the necessary support for an OBJCC variable in the
makefile and configure machinery; we default to clang
if we have it, otherwise whatever CC is (since gcc
might be the Apple gcc which does support Blocks).
