I don't execute the ctors until coverage is enabled because I have to manually find the symbols. The linker doesn't actually generate a ctor section for functions in text.startup in spite of what Juniper's linker commit would lead one to believe - presumably they have a private linker script in addition to a private gcov port. Thus, it really could just work fine as a module. Nonetheless, everything to be profiled needs to be compiled with instrumentation, so separating it out makes very little sense to me. Although, I suppose ctfconvert + dtrace module is somewhat analogous. > The modest increase in activation energy for that task seems worth it > for the short-term gains of reduced integration cost (this code will > greatly improve our ZFS-on-Linux test coverage.) > > Rod rightly points out that we haven't accepted SPDX tags alone as > license statements.
