I think this means that the Polly passes have not been registered 
(`initializePollyPasses` must be called someway in opt/clang_cc1/bugpoint). 
Linking from static libraries will NOT include `Polly.o` (and run its static 
initializers) unless it is needed to resolve at least one symbol.

PLEASE run `make/ninja check-polly` before uploading a patch.



================
Comment at: llvm/tools/opt/opt.cpp:533
-#ifdef LINK_POLLY_INTO_TOOLS
-  polly::initializePollyPasses(Registry);
-#endif
----------------
Where is the equivalent for this in your change? I see it's been done for 
`clang_cc1`, but not for `opt`/`bugpoint`.


================
Comment at: polly/CMakeLists.txt:210
 set_target_properties(polly-update-format PROPERTIES FOLDER "Polly")
-
----------------
[nit] Whitespace change


================
Comment at: polly/lib/CMakeLists.txt:27
 add_library(PollyCore OBJECT
+  Polly.cpp
   Analysis/DependenceInfo.cpp
----------------
Why this change? `Polly.cpp` should only be necessary for the loadable module, 
but not for `LLVM_LINK_POLLY_INTO_TOOLS`.
