Laurent Vivier 74912f6dad tcg: fix 16-byte vector operations detection
configure tries to detect if the compiler
supports 16-byte vector operations.

As stated in the comment of the detection
program, there is a problem with the system
compiler on GCC on Centos 7.

This program doesn't actually detect the problem
with GCC on RHEL7 on PPC64LE (Red Hat 4.8.5-28).

This patch updates the test to look more like
it is in QEMU helpers, and now detects the problem.

The error reported is:

  CC      ppc64-softmmu/accel/tcg/tcg-runtime-gvec.o
  ..//accel/tcg/tcg-runtime-gvec.c: In function ‘helper_gvec_shl8i’:

Michael S. Tsirkin 9edc19c939 make: switch from -I to -iquote
Our rule right now is to use <> for external headers,
"" for internal ones. The idea was to avoid conflicts
between e.g. a system file named <trace.h> and an
internal one by the same name.

Unfortunately we use -I compiler flag so it does not
help: a system file doing #include <trace.h> will
still pick up ours first.

To fix, switch to -iquote which is supported by both
gcc and clang and only affects #include "" directives.

As a side effect, this catches any future uses of
 #include <> for internal headers.

Because only recent versions of Linux include the support, they
are disabled by default.  Note that it also has to be disabled
for QEMU to run under Wine.

Thomas Huth 7e563bfb8a Polish the version strings containing the package version
Since commit 67a1de0d19 there is no space anymore between the
version number and the parentheses when running configure with
--with-pkgversion=foo :

 $ qemu-system-s390x --version
 QEMU emulator version 2.11.50(foo)

But the space is included when building without that option
when building from a git checkout:

 $ qemu-system-s390x --version
 QEMU emulator version 2.11.50 (v2.11.0-1494-gbec9c64-dirty)

The same confusion exists with the "query-version" QMP command.
Let's fix this by introducing a proper QEMU_FULL_VERSION definition
that includes the space and parentheses, while the QEMU_PKGVERSION
should just cleanly contain the package version string itself.
Note that this also changes the behavior of the "query-version" QMP
command (the space and parentheses are not included there anymore),
but that's supposed to be OK since the strings there are not meant
to be parsed by other tools.

Gerd Hoffmann 0e39c4aa7e build: try improve handling of clang warnings
This patch disables the pragma diagnostic -Wunused-but-set-variable for
clang in util/coroutine-ucontext.c.

This in turn allows us to remove it from the configure check, so the
CONFIG_PRAGMA_DIAGNOSTIC_AVAILABLE will succeed for clang.

With that in place clang builds (linux) will use -Werror by default,
which breaks the build due to warning about unaligned struct members.

Just turning off this warning isn't a good idea as it indicates
portability problems.  So make it a warning again, using
-Wno-error=address-of-packed-member.  That way it doesn't break the
build but still shows up in the logs.

Now clang builds qemu without errors.  Well, almost.  There are some
left in the rdma code.  Leaving that to the rdma people.  All others can
use --disable-rdma to workarounds this.

Gerd Hoffmann 1ef1ec2a44 audio: rename CONFIG_* to CONFIG_AUDIO_*
This avoids a name clash for CONFIG_SDL, which is used by both sdl video
support and sdl audio support.  It also more clear that this is a audio

Gerd Hoffmann 2373f7d581 ui/curses: build as module
Also drop curses libs from libs_softmmu.  Add CURSES_{CFLAGS,LIBS}
variables so we can use them for linking the curses module.

Also make target/unicore32/helper.o depend on curses which uses curses
directly for some reason ...

Alice Frosi 12f15c9155 Fix configure for s390 qemu on alpine and other busybox environments
In alpine docker image the qemu-system-s390x build is broken and
it throws this error:
qemu-system-s390x: Initialization of device s390-ipl failed: could not
load bootloader 's390-ccw.img'

The grep command of busybox uses regex. This fails on binary data
(e.g. stops on every \0), so it does not identify the string
BiGeNdIaN in the test case big/little. Therefore, it assumes
that the architecture is little endian.

This fix solves the grep problem by printing the content of
TMPO with strings

Marc-André Lureau d83414e1fd ucontext: annotate coroutine stack for ASAN
It helps ASAN to detect more leaks on coroutine stacks, and to get rid
of some extra warnings.

Before:

/basic/lifecycle
/basic/lifecycle: ==20781==WARNING: ASan doesn't fully support
makecontext/swapcontext functions and may produce false positives in
some cases!
==20781==WARNING: ASan is ignoring requested __asan_handle_no_return:
stack top: 0x7ffcb184d000; bottom 0x7ff6c4cfd000; size: 0x0005ecb50000
(25446121472)
False positive error reports may follow
For details see https://github.com/google/sanitizers/issues/189
OK

After:

tests/test-coroutine -p /basic/lifecycle
/basic/lifecycle: ==21110==WARNING: ASan doesn't fully support
makecontext/swapcontext functions and may produce false positives in
some cases!
OK

A similar work would need to be done for sigaltstack & windows fibers
to have similar coverage. Since ucontext is preferred, I didn't bother
checking the other coroutine implementations for now.

Update travis to fix the build with ASAN annotations.

Peter Maydell b1cef6d02f Drop remaining bits of ia64 host support
We dropped support for ia64 host CPUs in the 2.11 release (removing
the TCG backend for it, and advertising the support as being
completely removed in the changelog).  However there are a few bits
and pieces of code still floating about.  Remove those, too.

We can drop the check in configure for "ia64 or hppa host?"
entirely, because we don't support hppa hosts either any more.

The SDL 2.0 release was made in Aug, 2013:

  https://www.libsdl.org/release/

That will soon be 4 + 1/2 years ago, which is enough time to consider
the 2.0 series widely supported.

Thus we deprecate the SDL 1.2 support, which will allow us to delete it
in the last release of 2018. By this time, SDL 2.0 will be more than 5
years old.

Daniel P. Berrange b7715af2b3 ui: deprecate use of GTK 2.x in favour of 3.x series
The GTK 3.0 release was made in Feb, 2011:

  https://blog.gtk.org/2011/02/10/gtk-3-0-released/

That will soon be 7 years ago, which is enough time to consider
the 3.x series widely supported.

Thus we deprecate the GTK 2.x support, which will allow us to
delete it in the last release of 2018. By this time, GTK 3.x
will be almost 8 years old.
