How to define a MachineFunctionPass requireing one of the register allocation passes being executed first? Should there be a PassInfo for register allocation in Pass.h?

While trying to add a pass to the ARM back end I'm getting quite a lot of this assertion failure: Pass.cpp:255: llvm::Pass* llvm::PassInfo::createPass() const: Assertion `NormalCtor && "Cannot call createPass on PassInfo without default ctor!"' failed. A simple way to get it is to add two lines to ARMTargetMachine.cpp: #include "llvm/Transforms/Scalar.h" and PM.add(createSinkingPass()); in addIns...

How do i create PassInfo for a Pass and then register it on the PassRegistry? I need to add TargetLibraryInfoWrapperPass to the registry, because addImmutablePass() function asserts because it doesn't find Info for the pass.

...ng at the LoopInfo Analysis pass as an example, and found it defined the isAnalysis() method to return true. I assumed the method was overriden from some superclass (Pass, probably) and present in all analysis passes. However, a better look turns out that the method isn't really used anywhere. PassInfo does define the same method which is used, but PassInfo is not a superclass of LoopInfo. AFAICS, LoopInfo::isAnalysis (include/llvm/Analysis/LoopInfo.h:924) is unused and can/should be removed? Removing the method doesn't break compilation for me. Gr.

Hi, We use LLVM libraries to compile C++ code and noticed slow downs when multiple threads of a process were compiling at once. *perf *indicated that most of the CPU time was spent in a spin lock, which was being locked/unlocked from llvm::PassRegistry::getPassInfo(). We read the relevant LLVM code and found out that PassRegistry is a ManagedStatic and is shared among all threads in case of a multi-threaded setup. This sharing requires locking in PassRegistry's method, which becomes source of the contention. To get rid of the contention, we made a change...
