[Spice-devel] [PATCH spice-gtk v2 0/4] Another set of macOS pre-enablement patches

[Christophe de Dinechin]

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

This patch set eliminates warnings detected by clang with respect
to type alignments. Vittorio Toso had submitted something
similar. In this version, I took into account comments by
Christophe Fergeau regarding how to know which casts were
aligned and which ones were not aligned. I added some
instrumentation to detect the two cases.

The casts that are supposed to be aligned will issue a warning
if data is actually misaligned.

The casts that are known to be misaligned can still be checked
by setting environment variable SPICE_DEBUG_ALIGNMENT=1

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

Christophe de Dinechin (4):
  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 check for macOS, disable ucontext on macOS (deprecated)
