# HOW IT WORKS
|
||
|
|
#
|
||
|
|
# - Gather all unresolved symbols and libraries needed by the programs
|
||
|
|
# and reduced libraries
|
||
|
|
# - Gather all symbols provided by the already reduced libraries
|
||
|
|
# (none on the first pass)
|
||
|
|
# - If all symbols are provided we are done
|
||
|
|
# - go through all libraries and remember what symbols they provide
|
||
|
|
# - go through all unresolved/needed symbols and mark them as used
|
||
|
|
# - for each library:
|
||
|
|
# - find pic file (if not present copy and strip the so)
|
||
|
|
# - compile in only used symbols
|
||
|
|
# - strip
|
||
|
|
# - back to the top
|
||
|
|
|
||
|
|
# TODO
|
||
|
|
# * complete argument parsing as given as comment in main
