[PULL 01/21] configure: Allow passing extra Objective C compiler flags

[Philippe Mathieu-Daudé]

From: Philippe Mathieu-Daudé <f4bug@amsat.org>

We can pass C/CPP/LD flags via CFLAGS/CXXFLAGS/LDFLAGS environment
variables, or via configure --extra-cflags / --extra-cxxflags /
--extra-ldflags options. Provide similar behavior for Objective C:
use existing flags from $OBJCFLAGS, or passed via --extra-objcflags.

[PULL 02/21] tests/fp/berkeley-testfloat-3: Ignore ignored #pragma directives

[Philippe Mathieu-Daudé]

From: Philippe Mathieu-Daudé <f4bug@amsat.org>

Since we already use -Wno-unknown-pragmas, we can also use
-Wno-ignored-pragmas. This silences hundred of warnings using
clang 13 on macOS Monterey:

  [409/771] Compiling C object tests/fp/libtestfloat.a.p/berkeley-testfloat-3_source_test_az_f128_rx.c.o

  #pragma STDC FENV_ACCESS ON
               ^
  1 warning generated.

[PULL 05/21] hvf: Remove deprecated hv_vcpu_flush() calls

[Philippe Mathieu-Daudé]

From: Philippe Mathieu-Daudé <f4bug@amsat.org>

When building on macOS 11 [*], we get:

  In file included from ../target/i386/hvf/hvf.c:59:
  ../target/i386/hvf/vmx.h:174:5: error: 'hv_vcpu_flush' is deprecated: first deprecated in macOS 11.0 - This API has no effect and always returns HV_UNSUPPORTED [-Werror,-Wdeprecated-declarations]
      hv_vcpu_flush(vcpu);
      ^
  /Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/System/Library/Frameworks/Hypervisor.framework/Headers/hv.h:364:20: note: 'hv_vcpu_flush' has been explicitly marked deprecated here
  extern hv_return_t hv_vcpu_flush(hv_vcpuid_t vcpu)
                     ^

Since this call "has no effect", simply remove it ¯\_(ツ)_/¯

Not very useful deprecation doc:
https://developer.apple.com/documentation/hypervisor/1441386-hv_vcpu_flush

[*] Also 10.15 (Catalina):

From: Philippe Mathieu-Daudé <f4bug@amsat.org>

When configuring QEMU with --enable-modules we get on macOS:

  --- stderr ---
  Dependency ui-dbus cannot be satisfied

ui-dbus depends on pixman and opengl, so add these dependencies
to audio-dbus.

Without this change audio_bug aborts when the bug condition is met,
which discards following useful logs. Call abort after such logs.

[PULL 10/21] coreaudio: Always return 0 in handle_voice_change

[Philippe Mathieu-Daudé]

From: Akihiko Odaki <akihiko.odaki@gmail.com>

handle_voice_change() is a CoreAudio callback function as of CoreAudio type
AudioObjectPropertyListenerProc, and for the latter MacOSX.sdk/System/
Library/Frameworks/CoreAudio.framework/Headers/AudioHardware.h
says "The return value is currently unused and should always be 0.".

[PULL 11/21] audio: Rename coreaudio extension to use Objective-C compiler

[Philippe Mathieu-Daudé]

From: Philippe Mathieu-Daudé <f4bug@amsat.org>

The coreaudio library includes Objective-C declarations (using the
caret '^' symbol to declare block references [*]). When building
with a C compiler we get:

  [175/839] Compiling C object libcommon.fa.p/audio_coreaudio.c.o
    In file included from /Library/Developer/CommandLineTools/SDKs/MacOSX12.sdk/System/Library/Frameworks/CoreAudio.framework/Headers/CoreAudio.h:18,

          |  ^
    FAILED: libcommon.fa.p/audio_coreaudio.c.o

Rename the file to use the Objective-C default extension (.m) so
meson calls the correct compiler.

[PULL 12/21] osdep: Avoid using Clang-specific __builtin_available()

[Philippe Mathieu-Daudé]

From: Philippe Mathieu-Daudé <f4bug@amsat.org>

Remove the Clang specific __builtin_available() to allow building
with GCC, otherwise we get:

        |                                  )

Beside, on macOS Catalina we get 2254 times:

Fix by using a stricker toolchain version low range, replacing
MAC_OS_X_VERSION_MAX_ALLOWED by MAC_OS_X_VERSION_MIN_REQUIRED.

Commit 235b523dba ("meson: Use find_program() to resolve the
entitlement.sh script") didn't correctly fixed the issue, as
the script is still resolved for each target. Move the check
earlier, before processing each target.

[PULL 17/21] ui/cocoa: add option to disable left-command forwarding to guest

[Philippe Mathieu-Daudé]

From: Carwyn Ellis <carwynellis@gmail.com>

When switching between guest and host on a Mac using command-tab the
command key is sent to the guest which can trigger functionality in the
guest OS. Specifying left-command-key=off disables forwarding this key
to the guest. Defaults to enabled.

Also updated the cocoa display documentation to reference the new
left-command-key option along with the existing show-cursor option.

[PULL 18/21] ui/cocoa: release mouse when user switches away from QEMU window

[Philippe Mathieu-Daudé]

From: Carwyn Ellis <carwynellis@gmail.com>

This resolves an issue where using command-tab to switch between QEMU
and other windows on the host can leave the mouse pointer visible.

By releasing the mouse when the user switches away, the user must left
click on the QEMU window when switching back in order to hide the
pointer and return control to the guest.

This appraoch ensures that the calls to NSCursor hide and unhide are
always balanced and thus work correctly when invoked.

[PULL 19/21] ui/cocoa: capture all keys and combos when mouse is grabbed

[Philippe Mathieu-Daudé]

From: Gustavo Noronha Silva <gustavo@noronha.dev.br>

Applications such as Gnome may use Alt-Tab and Super-Tab for different
purposes, some use Ctrl-arrows so we want to allow qemu to handle
everything when it captures the mouse/keyboard.

However, Mac OS handles some combos like Command-Tab and Ctrl-arrows
at an earlier part of the event handling chain, not letting qemu see it.

We add a global Event Tap that allows qemu to see all events when the
mouse is grabbed. Note that this requires additional permissions.

[PULL 20/21] ui/cocoa: add option to swap Option and Command

[Philippe Mathieu-Daudé]

From: Gustavo Noronha Silva <gustavo@noronha.dev.br>

On Mac OS X the Option key maps to Alt and Command to Super/Meta. This change
swaps them around so that Alt is the key closer to the space bar and Meta/Super
is between Control and Alt, like on non-Mac keyboards.

It is a cocoa display option, disabled by default.

[PULL 21/21] MAINTAINERS: Volunteer to maintain Darwin-based hosts support

From: Philippe Mathieu-Daudé <f4bug@amsat.org>

While I am not an experienced Darwin OS user, I now have to
use a macOS based workstation and alike CI, meaning I should
easily spot regressions and test fixes. I therefore volunteer
to collect Darwin related patches and keep QEMU in good state
on macOS, and to some extent iOS.
