[LLVMdev] Pass Incompatibility
...ve a transformation where I'd like to use both DominatorTree (for ExtractCodeRegion), and DemoteRegisterToMemory (i.e., reg2mem). The transformation is phased, so all occurrences of getAnalysis<DominatorTree>(Function) happen before any occurrence of getAnalysisID<FunctionPass>(&DemoteRegisterToMemoryID, Function).
If I register these two passes with DominatorTree first, I get the following assert.
PassAnalysisSupport.h:239: AnalysisType& llvm::Pass::getAnalysisID(const void*, llvm::Function&) [with AnalysisType = llvm::DominatorTree]: Assertion `ResultPass && "Unable to fin...

I believe that reg2mem is a transform pass, correct? If so, then you
should not be making it a prerequisite for your pass. Instead, whatever
is scheduling the set of transform passes (e.g, the user on the opt
command line or the source code that schedules your pass to be run with...

[LLVMdev] run -mem2reg and -reg2mem programmably from within a Pass
I guess AU.addRequiredID(DemoteRegisterToMemoryID) would do the trick.

[LLVMdev] run -mem2reg and -reg2mem programmably from within a Pass
I am currently building a BasicBlock pass which requires to run -reg2mem
before it, and need to run -mem2reg after it to clean up.
So, I want to specify -reg2mem as one of the pre-requisite passes to it, as:
class MyPass: public BasicBlockPass{
virtual void getAnalysisUsage(AnalysisUsage &AU){
...
AU.addRequired<RegToMem>();
...
}
};

[LLVMdev] Specify dominator for BasicBlock to avoid "Instruction does not dominate all uses!"
Hi, I tried adding the PHI nodes in BB_unique, and it works for the simple
case described here, but in case the nodes were declared in some
predecessors of ExitBB1 and used in ExitBB1_redirect and its successors, it
won't work, unless I create entries for all of them in BB_unique.
B1 (declares PHI_1) B3
