      configure: Put tempfiles in a subdir of the build directory · 8cd05ab6
      由 Peter Maydell 提交于 
      When libtool support was added to configure, the new temporary files
were left out of the list of files cleaned up on exit; this results
in a lot of stale .lo files being left around in /tmp. Worse, libtool
creates a /tmp/.libs directory which we can't easily clean up.

Put all our temporary files in a single temporary directory created
as a subdirectory of the build directory, so we can easily clean it up,
and don't need fragile or complicated code for creation to avoid it
clashing with temporary directories from other instances of QEMU
configure or being subject to attack from adversaries who can write
to /tmp.

Since the temporaries now live in the build tree, we have no
need to jump through hoops with a trap handler to try to remove
them when configure exits; this fixes some weird bugs where hitting
^C during a configure run wouldn't actually make it stop, because
we would run the trap handler but then not stop. (It is possible
to get the trap handler semantics right but it is convoluted largely
because of bugs in dash, so it is simpler to just avoid it.)

Note that "temporary files go in the build directory, not /tmp" is
the way autoconf behaves.

      gitignore: cleanups #2 · 5d77c8f9
      由 Michael Tokarev 提交于 
      A few more cleanups for .gitignore file.
The final goal is to have only files in there which
are generated during build.  Things like .orig or
.gdbinit are definitely not generated during build.
Also, anchor a few more build-time directories.

      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.

      gitignore: anchor all ignored names · 5556332a
      由 Michael Tokarev 提交于 
      by default, patterns/names in .gitignore are applied
recursively to all subdirectories.  So any name mentioned
in .gitignore is ignored in all subdirectores.  This is good
for, say. object files (*.o), but not good for particular
names which should be ignored only in one directory.  For
example, qemu-img.1 file is generated in the top directory,
and it should be ignored only there, not in some subdir.

At first, this might not matter much, but we have lots of
examples already where it actually does not help at all.
For example, top-level .gitignore ignores a file/dir named
"patches" (which is very questionable by itself), but it
is applied recursively, so git also ignores, for example,
debian/patches/ which should not be ignored.

So anchor all the names where appropriate.  .gitignore
should be cleaned up further, which will be addressed in
a subsequent patch.

    gitignore: ignore more files

I'm not sure how this went in.  The thing is that
ignoring *.patch, in my opinion, is just wrong.
Especially for downstreams who apply patches for
real.

      Add a DTrace tracing backend targetted for SystemTAP compatability · b3d08c02
      由 Daniel P. Berrange 提交于 
      This introduces a new tracing backend that targets the SystemTAP
implementation of DTrace userspace tracing. The core functionality
should be applicable and standard across any DTrace implementation
on Solaris, OS-X, *BSD, but the Makefile rules will likely need
some small additional changes to cope with OS specific build
requirements.

This backend builds a little differently from the other tracing
backends. Specifically there is no 'trace.c' file, because the
'dtrace' command line tool generates a '.o' file directly from
the dtrace probe definition file. The probe definition is usually
named with a '.d' extension but QEMU uses '.d' files for its
external makefile dependancy tracking, so this uses '.dtrace' as
the extension for the probe definition file.

The 'tracetool' program gains the ability to generate a trace.h
file for DTrace, and also to generate the trace.d file containing
the dtrace probe definition.

Example usage of a dtrace probe in systemtap looks like:

  probe process("qemu").mark("qemu_malloc") {
    printf("Malloc %d %p\n", $arg1, $arg2);
  }

* .gitignore: Ignore trace-dtrace.*
* Makefile: Extra rules for generating DTrace files
* Makefile.obj: Don't build trace.o for DTrace, use
  trace-dtrace.o generated by 'dtrace' instead
* tracetool: Support for generating DTrace data files
