I find a bug in document llvm/docs/WritingAnLLVMPass.html#debughints Since the PassManager class is in the namespace llvm, we should use command (gdb) break llvm::PassManager::run to set breakpoint. Otherwise we get error message: (gdb) break PassManager::run Can't find member of namespace, class, struct, or union named "PassManager::run...

I'm wondering if the documentation for LoopPass ( http://llvm.org/docs/WritingAnLLVMPass.html#LoopPass) is misleading or incorrect (or if I'm just missing something.)

Hello, I'm a little confused about the 3th and 4th arguments in the registration function, explained here: http://llvm.org/releases/3.3/docs/WritingAnLLVMPass.html e.g static RegisterPass<Hello> X("hello", "Hello World Pass", false /* Only looks at CFG */, false /* Analysis Pass */); "Lastly, we *register our class* <http://llvm.org/releases/3.3/docs/WritingAn...

...which the NPM does). I'll leave it to folks (Chandler probably has the most context here) to provide some more detail there if they can/have time. Historically speaking, all of the LLVM pass managers have been designed to support multithreaded compilation (check out the ancient history of the WritingAnLLVMPass <http://llvm.org/docs/WritingAnLLVMPass.html> doc if curious). The problem is that LLVM has global use-def chains on constants, functions and globals, etc, so it is impractical to do this. Every “inst->setOperand” would have to be able to take locks or use something like software transac...

I am trying to write a ModulePass which requires PostDominator sets for every function in the module. Now finding post dominators is a function pass. The link on the llvm.org website says that : "Currently it is illegal for a ModulePass<http://llvm.org/docs/WritingAnLLVMPass.html#ModulePass>to require a FunctionPass <http://llvm.org/docs/WritingAnLLVMPass.html#FunctionPass>. This is because there is only one instance of the FunctionPass<http://llvm.org/docs/WritingAnLLVMPass.html#FunctionPass>object ever created, thus nowhere to store information for all...

...the statement "using namespace llvm;" What I'm saying is that it has been my experience that when a pass Y depends on another pass X, i.e, Y is a required analysis of X, then Y must be defined within the llvm namespace rather than in an anonymous namespace as http://llvm.org/docs/WritingAnLLVMPass.html suggests it should be. I'm wondering if that is correct, or if I'm missing something. Regards, Ryan Devang Patel wrote: > On Sep 26, 2006, at 5:49 PM, Ryan M.

In a first phase, all intrinsic instructions are discarded after extracting their data into annotations attached to the relevant Function. Then, a second phase wipes out the
