6 years ago It isn't a warning, it is an informational note. The var-tracking optimization pass has an internal limit to avoid using too much time or memory. If the limit is exceeded, then it tries doing less work, and if that still fails it skips the function. You can increase the limit with --param max-vartrack-size=X. If you specify X as 0, then the size is unlimited.
I don't know anything about a libdummy.so, but I see a libdummy_rocc.so. Perhaps that is what you want? If so, try --extension=dummy_rocc.

spike --extension=dummy couldn't find extension 'dummy' (or library 'libdummy.so')
why I am getting warning related to disasm.cc I am trying to use spike for a dummy or sha3 accelerator but I could not do it. thanks
