# Find exported symbols that can be made non-exported.
|
|
#
|
|
# Noting that (a) parsing these commands is a pain, the output is quite irregular and (b) I'm fumbling in the
|
|
# dark here, trying to guess what exactly constitutes an "import" vs an "export" of a symbol, linux linking
|
|
# is rather complex.
|
|
#
|
|
# Takes about 5min to run on a decent machine.
|
|
#
|
|
# The standalone function analysis is reasonable reliable, but the class/method analysis is less so
|
|
# (something to do with destructor thunks not showing up in my results?)
|
|
#
|
|
# Also, the class/method analysis will not catch problems like
|
|
# 'dynamic_cast from 'Foo' with hidden type visibility to 'Bar' with default type visibility'
|
|
# but loplugin:dyncastvisibility will do that for you
|
