# 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.
