cairo, harfbuzz: rework atomic dependencies
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.
