vmjc and CallGraphSCCPass

Project Infrastructure LLVM Dev List Archives
#1

How can I vmjc to run CallGraphSCCPasses? I wrote a test pass that does nothing, and all vmjc says is:

vmjc: PassManager.cpp:1604: virtual void llvm::ModulePass::assignPassManager(llvm::PMStack&, llvm::PassManagerType): Assertion `!PMS.empty() && "Unable to find appropriate Pass Manager"' failed.
0 vmjc 0x08a6bfd8
Aborted

Running even a built in pass like prune-eh fails as well.

From what I can tell, this is because the only PassManager on the PMStack is a FunctionPassManager, and assignPassManager pops this off, leaving the PMStack empty. Then it fails.

Thanks,
Michael

Hi Michael,

Currently, you can only run Function passes with vmjc. To run module passes, you can take the resulting .bc and call the opt tool on it.
