# This script is intended to be used by binary_search_state.py, as
|
|
# part of the binary search triage on the Android source tree. This script
|
|
# symlinks a list of object files from the 'bad' build tree into the working
|
|
# build tree, for testing.
|
|
#
|
|
# It is highly recommended to not use --noincremental with these scripts. If the
|
|
# switch scripts are given non incremental sets of GOOD/BAD objects, make will
|
|
# not be able to do an incremental build and will take much longer to build.
