I wasn't watching top at the time, so I don't know how much swap was in use. Total available was 4 GB, which certainly seems like it ought to be enough. The swap was on both microSD and USB flash. I've run make clean in /usr/src/lib/clang/libllvm and restarted a -j4 buildworld with the -DNO_CLEAN option, and also set sysctl vm.pageout_update_period=0 to see what would happen. Within a few minutes buildworld stopped, the tail of the log file contained --- X86GenEVEX2VEXTables.inc --- llvm-tblgen -gen-x86-EVEX2VEX-tables -I /usr/src/contrib/llvm/include -I /usr/src/contrib/llvm/lib/Target/X86 -d X86GenEVEX2VEXTables.inc.d -o X86GenEVEX2VEXTables.inc /usr/src/contrib/llvm/lib/Target/X86/X86.td --- X86GenFastISel.inc --- llvm-tblgen -gen-fast-isel -I /usr/src/contrib/llvm/include -I /usr/src/contrib/llvm/lib/Target/X86 -d X86GenFastISel.inc.d -o X86GenFastISel.inc /usr/src/contrib/llvm/lib/Target/X86/X86.td --- X86GenDAGISel.inc --- Killed *** [X86GenDAGISel.inc] Error code 137 make[6]: stopped in /usr/src/lib/clang/libllvm 1 error make[6]: stopped in /usr/src/lib/clang/libllvm *** [all_subdir_lib/clang/libllvm] Error code 2 make[5]: stopped in /usr/src/lib/clang I'll try again, this time with USB swap turned off.
