Ok, here's a new attempt with SRCDIR and OBJDIR constant between the two builds. This time, /boot/kernel/kernel, /boot/loader, /boot/pxeboot and /boot/zfsloader differ. According to strings(1), the only difference is the timestamp. E.g. the kernel: < @(#)FreeBSD 9.0-CURRENT #0 r215143: Thu Nov 11 22:58:34 CET 2010 < FreeBSD 9.0-CURRENT #0 r215143: Thu Nov 11 22:58:34 CET 2010 --- > @(#)FreeBSD 9.0-CURRENT #0 r215143: Thu Nov 11 23:29:17 CET 2010 > FreeBSD 9.0-CURRENT #0 r215143: Thu Nov 11 23:29:17 CET 2010 Since the SVN rev. is recorded, I think a timestamp is redundant. Any ideas where I can disable the timestamps in the source? Also, /usr/bin/[clang|clang++|tblgen] differ, i.e.: 248735,248736c248735,248736 < N135_GLOBAL__N__usr_home_erik_freebsd_head_src_lib_clang_libllvmcore_.._.._.._contrib_llvm_lib_VMCore_PrintModulePass.cpp_00000000_E8B12D4D15PrintModulePassE < N135_GLOBAL__N__usr_home_erik_freebsd_head_src_lib_clang_libllvmcore_.._.._.._contrib_llvm_lib_VMCore_PrintModulePass.cpp_00000000_E8B12D4D17PrintFunctionPassE --- > N135_GLOBAL__N__usr_home_erik_freebsd_head_src_lib_clang_libllvmcore_.._.._.._contrib_llvm_lib_VMCore_PrintModulePass.cpp_00000000_BDCFB9C615PrintModulePassE > N135_GLOBAL__N__usr_home_erik_freebsd_head_src_lib_clang_libllvmcore_.._.._.._contrib_llvm_lib_VMCore_PrintModulePass.cpp_00000000_BDCFB9C617PrintFunctionPassE I'm not sure what to do with this except pass it on to the LLVM lists.
