...version. On the original call that creates this class, I'd like to pass the address of the address of the TargetLoweringBase class. That way I can insert a function pass before this pass which examines the function attributes and changes the pointer. So we would get: ImmutablePass * llvm::createBasicTargetTransformInfoPass(const TargetLoweringBase **TLI_) { return new BasicTTI(TLI); } we would add the variable TargetLoweringBase **TLI_ and at the beginning of each pass TLI = *TLI_; Maybe there is a more elegant way to do this but this is essentially what I need to do.

...sisPasses(FPManager); Here is what the target does: void X86TargetMachine::addAnalysisPasses(PassManagerBase &PM) { // Add first the target-independent BasicTTI pass, then our X86 pass. This // allows the X86 pass to delegate to the target independent layer when // appropriate. PM.add(createBasicTargetTransformInfoPass(this)); PM.add(createX86TargetTransformInfoPass(this)); } > LV: The Widest type: 32 bits. > LV: The Widest register is: 32 bits. This strongly looks like no target has added a target transform info pass so we default to NoTTI. But, it could also be that you don’t have the right sub tar...

I would need this to work when calling the vectorizer through the function pass manager. Unfortunately I am having the same problem there: LV: The Widest type: 32 bits. LV: The Widest register is: 32 bits. It's not picking the target information, although I tried with and without the target triple in the module. Any idea what could be wrong?

That may depend on what CPU is picks by default; Frank,
