[Spice-devel] [PATCH spice-gtk v5 0/5] Repair macOS builds for spice-gtk

[Christophe de Dinechin]

From: Christophe de Dinechin <dinechin at redhat.com>

This patch set contains various fixes that repair macOS builds for
spice-gtk (and presumably clang builds as a side effect), notably:

- Fixes for clang-specific warnings, notably on alignment
- Addition of macOS detection in configure script
- A couple minor portablity fixes

This requires an update to spice-common, see
https://lists.freedesktop.org/archives/spice-devel/2017-May/037505.html.
The reference to submodule  in this patch serie is updated with a
reference that can be fetched from https://github.com/c3d/spice-common.git.

Version 2 takes into account comments by Frediano Ziglio and Pavel Grunt,
specifically:

- Clarify purpose and behavior of macros in patch commit message
- Change one case to 'unaligned'
- Improve way to avoid 'unused variable' warning

Acked by: Christophe Fergeau <cfergeau at redhat.com>

Version 3 takes into account comments made by Christophe Fergeau in
his ack message, specifically:

- Improve the log message description of SPICE_(UN)ALIGNED_CAST.
  Hopefully the new one is better.

- Make spaces after commas consistent

In addition, v3 re-enables ucontext on macOS, following comments
that this is the right thing to do for performance. This required the
elimination of one more alignment warning.

Version 4 takes into account comments made by Pavel and Frediano,
specifically:

- Reorder the previous iteration to group things more logically
- Add a TODO comment for macOS in set_mouse_accel

Version 5 adds the --enable-alignment-checks configuration option
and disables all runtime checks by default.

Christophe de Dinechin (5):
  Add check for macOS
  Avoid clang warnings on casts with stricter alignment requirements
  Avoid warning about snprintf on non-Linux platforms
  Remove warning about unused variable when building on macOS
  Add configure option --enable-alignment-checks
