Although not perfect, but may i suggest to consider putting the
attached contrib/unused_functions.py into our tree?
Just for fun i'm attaching output for fortran, c, cp as per the
"Examples" comment in the header of the script.
sample line for cp:
gcc/cp/cvt.o: Symbol 'cp_get_callee_fndecl(tree_node*)' declared extern but never referenced externally
sample for c:
gcc/c/c-decl.o: Symbol 'pending_invalid_xref_location' declared extern but never referenced externally
gcc/c/c-decl.o: Symbol 'pending_invalid_xref' declared extern but never referenced externally
I may find time to take care of the fortran spots later on, fwiw.
As per the comment inline, one could add support for extracting
archive-members. This would allow to optionally put the script
near the actual linking of e.g the compilers to see unwarranted extern
symbols quickly. But OTOH maybe that's a bit too much. :)
HTH
PS: I have to admit that flagging unused fields is a nice thing. Does
somebody know of an existing gcc plugin that does that? Or a secret LTO
knob to track or flag these?
