# This BUILD_CONFIG option is a bit like bootstrap-debug, but rather# than comparing stripped object files, it compares compiler internal# state during stage3.  Both can be used simultaneously. # This makes it slower than bootstrap-debug alone, for there's# additional dumping and recompilation during stage3.# bootstrap-debug-big can avoid the recompilation, if plenty of disk# space is available.
