This commit handles the reverse dependency tree of cairo in terms of atomic dependencies. There are two main changes: - cairo in fact no longer needs atomic operations. It can perfectly build without any __sync built-in, as was tested using an ARC toolchain without atomics, and a SPARC toolchain. Optionally, Cairo can use the __atomic builtins provided by gcc >= 4.7, so support for this is added as well. Thanks to this change, the BR2_ARCH_HAS_ATOMICS dependency is removed from cairo and all its reverse dependencies. - harfbuzz does require the __sync built-in for 4 bytes integers, so we add a dependency on BR2_TOOLCHAIN_HAS_SYNC_4 to harfbuzz and all its reverse dependency, the main one being the pango package. Due to this, the vast majority of gtk-related packages are moved to a dependency on BR2_ARCH_HAS_ATOMICS (which used to be due to cairo) to a dependency on BR2_TOOLCHAIN_HAS_SYNC_4 (due to pango -> harfbuzz). In detail: - cairo Remove BR2_ARCH_HAS_ATOMICS dependency, link against -latomic when gcc >= 4.8 in order to use the __atomic functions. - harfbuzz Add dependency on BR2_TOOLCHAIN_HAS_SYNC_4 - cairomm, gst-plugins-good, gst1-plugins-good, libgdiplus, libsvg-cairo, weston Remove BR2_ARCH_HAS_ATOMICS dependency (since cairo no longer needs atomics) - enlightenment, cwiid, gst-plugins-bad, gst-plugins-base, gst1-plugins-bad, gst1-plugins-base, gtkmm3, libevas-generic-loaders, libfm, libgail, libgtk2, libgtk3, librsvg, openbox, opencv, opencv3, pango, pangomm, pcmanfm, pinentry, rrdtool, webkit, webkitgtk24, xscreensaver Switch from a BR2_ARCH_HAS_ATOMICS dependency to a BR2_TOOLCHAIN_HAS_SYNC_4 (they depend on pango, harfbuzz, gtk, or some other related package) - directfb Remove BR2_ARCH_ATOMICS dependency of the BR2_PACKAGE_DIRECTFB_SVG (since cairo can build without atomics), but add a BR2_TOOLCHAIN_HAS_SYNC_4 dependency on BR2_PACKAGE_DIRECTFB itself since it does use __sync built-ins. This replaces the !BR2_sparc dependency. Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>

Pango is a library for laying out and rendering of text, with an
|
|
emphasis on internationalization. Pango can be used anywhere that
|
|
text layout is needed, though most of the work on Pango so far has
|
|
been done in the context of the GTK+ widget toolkit. Pango forms the
|
|
core of text and font handling for GTK+-2.x.
