d865f30739 target-xtensa: fix CCOUNT for conditional branches
Taken conditional branches fail to update CCOUNT register because
accumulated ccount_delta is reset during translation of non-taken
branch. To fix it only update CCOUNT once per conditional branch
instruction translation.

This fixes guest linux freeze on LTP waitpid06 test.

9d70c4b7b8 exec: fix TB invalidation after breakpoint insertion/deletion
tb_invalidate_phys_addr has to be called with the exact physical address of
the breakpoint we add/remove, not just the page's base address.
Otherwise we easily fail to flush the right TB.

This breakage was introduced by the commit f3705d5329 "memory: make
phys_page_find() return an unadjusted".

This appeared to work for some guest architectures because their
cpu_get_phys_page_debug implementation returns full translated physical
address, not just the base of the TARGET_PAGE_SIZE-sized page.

bbbc0e244e w32: Fix broken build (missing include file)
dump.c was recently added to the code. It unconditionally
includes sys/procfs which is not available with MinGW (w32, w64).

It looks like this file is not needed at all (tested on Linux),
so I removed it completely.

Some other include statements are also redundant because they are
already included in qemu-common, therefore they were removed, too.

3294ce1893 do not include <libutil.h> needlessly or if it doesn't exist
<libutil.h> and <util.h> on *BSD (some have one, some another)
were #included just for openpty() declaration.  The only file
where this function is actually used is qemu-char.c.

In vl.c and net/tap-bsd.c, none of functions declared in libutil.h
(login logout logwtmp timdomain openpty forkpty uu_lock realhostname
fparseln and a few others depending on version) are used.

Initially the code which is currently in qemu-char.c was in vl.c,
it has been removed into separate file in commit 0e82f34d07
Fri Oct 31 18:44:40 2008, but the #includes were left in vl.c.
So with vl.c, we just remove includes - libutil.h, util.h and
pty.h (which declares only openpty() and forkpty()) from there.

The code in net/tap-bsd.c, which come from net/tap.c, had this

Author: Mark McLoughlin <markmc@redhat.com>

    net: split all the tap code out into net/tap.c

Note this commit not only moved stuff out of net.c to net/tap.c,
but also rewrote large portions of the tap code, and added these
completely unnecessary #includes -- as usual, I question why such
a misleading commit messages are allowed.

Again, no functions defined in libutil.h or util.h on *BSD are
used by neither net/tap.c nor net/tap-bsd.c.  Removing them.

And finally, the only real user for these #includes, qemu-char.c,
which actually uses openpty().  There, the #ifdef logic is wrong.
A GLIBC-based system has <pty.h>, even if it is a variant of *BSD.
So __GLIBC__ should be checked first, and instead of trying to
include <libutil.h> or <util.h>, we include <pty.h>.  If it is not
GLIBC-based, we check for variations between <*util.h> as before.

This patch fixes build of qemu 1.1 on Debian/kFreebsd (well, one
of the two problems): it is a distribution with a FreeBSD kernel,
so it #defines at least __FreeBSD_kernel__, but since it is based
on GLIBC, it has <pty.h>, but current version does not have neither
<util.h> nor <libutil.h>, which the code tries to include 3 times
but uses only once.

99100dc3b5 build: move rules for nesting to Makefile.objs
At this point we will start adding nesting behavior to other files
than Makefile.target.  Because Makefile.objs is included by
Makefile.target, it is simpler to move the processing of
subdirectories there.

To enable this, only add per-target files to obj-y.  Use a separate
variable for the linker dependencies, all-obj-y.  This variable includes
obj-y and also all objects that are taken from other directories.

This adds the 'magic' rules that take care of subdirectories.
The subdirectory makefiles in the source tree are not complete; they
only define some variables (listed in nested-vars) according to the

The magic rules descend into subdirectory makefiles and gather the
evaluated values of those variables.  The values from all subdirectories
are joined together, each prefixed with the subdirectory name, and used
by the "real" makefiles.
