Kefu Chai 1b9ad6ca97 arch,cmake: compile ppc.c on all powerpc machines ... * cmake/modules/SIMDExt.cmake: define HAVE_PPC for 32-bit PowerPC. * src/arch/CMakeLists.txt: compile ppc.c for all PowerPC architectures, including powerpc (32-bit PowerPC), ppc64el (64-bit Little Endian PowerPC) and ppc64 (64-bit Big Endian PowerPC). before this change, ppc.c is only compiled if HAVE_POWER8 is defined. but Power8 is a 64-bit PowerPC architecture. while in src/arch/probe.cc, we check for `defined(__powerpc__) || defined(__ppc__)`, if this is true, ceph_arch_ppc_probe() is used to check for the support of Altivec. but on non-power8 PowerPC machines, the linker fails to find the symbols like ceph_arch_ppc_probe(), as ppc.c is not compiled on them. in this change, ppc.c is compiled on all PowerPC architectures, so that ceph_arch_ppc_probe() is also available on non-power8 machines. this change does not impact the behavior of non-power8 machines. because on them, the runtime check would fail to detect the existence of PPC_FEATURE2_VEC_CRYPTO instructions.
