can. You seem to be describing what GCC calls "simple IPA

Hello,
If local_function_and_variable_visibility was not a simple IPA pass it
would not have been called once per file but once per function (as it is
with GIMPLE pass).
I feel this is normal that this pass is run 2 times because it is run
before any link operations.
However, I don't know ex

Yes,
function bodies, and if so
how is this achieved? cgraph_function_body_availability seems to only be
half the story.
I am using GCC 4.6.0 with the gold linker plugin (binutils 2.21).
