Both packages are coupled, so both are bumped and build-tested. The atomics' support patch is no longer needed, and neither is the autoreconf option, and SPARC64 is no longer broken. To make sure of this, one config of each of the following archs was tested (base defconfig in parens): - PowerPC (qemu_ppc_g3beige_defconfig) - SPARC (qemu_sparc_ss10_defconfig) - SPARC64 (qemu_sparc64_sun4u_defconfig) Signed-off-by: Mario J.

# See src/google/protobuf/stubs/platform_macros.h for supported archs.

# On PowerPC, the __atomic_*() built-ins for 1-byte, 2-byte and 4-byte
|
|
# types are available built-in. However, the __atomic_*() built-ins for
|
|
# 8-byte types is implemented via libatomic, so only available since gcc
|
|
# 4.8.
|
|
#
|
|
# In Buildroot, to simplify things, we've decided to simply require gcc
|
|
# 4.8 as soon as the architectures has at least one __atomic_*() built-in
|
|
# variant that requires libatomic.
|
|
#
|
|
# Since protobuf most likely only uses the 1, 2 and 4-byte variants, it
|
|
# *could* technically build with gcc 4.7. This is probably not a big deal,
|
|
# and we can live with requiring gcc 4.8 on PowerPC to build protobuf.
|
|
#
|
|
# host-protobuf only builds on certain architectures
