[IRBuilder] Improve setting of DebugLoc in SetInsertPoint. #147091

abidh · 2025-07-04T17:25:37Z

Currently, in SetInsertPoint(BasicBlock *TheBB, BasicBlock::iterator IP) if the IP is pointing to the end of the TheBB, the debugLoc is not changed although the insertion point now points to a different location. This has been source of many problems in the OMPIRBuilder.

In OMPIRBuilder, the following code pattern is quite common.

  auto OldIP = Builder.saveIP();
  Builder.SetInsertPoint(/* some new location */);
  // Generate some code.
  Builder.restoreIP(OldIP);

An example can be seen here. If the OldIP is pointing to the end of the BasicBlock, SetInsertPoint will not call SetCurrentDebugLocation and we have a mismatch between InsertPoint and the DebugLoc. This causes many subtle bugs like 147063.

I fixed it by by using the debug location of the last instruction in the BasicBlock if the InsertPoint is at the end. Some clang OpenMP tests needed minor adjustments to work with this change.

Fixes #147063.

Polite ping.

SLTozer · 2025-07-16T10:36:35Z

I'm not sure I agree with the principle of this change; the current behaviour of not getting a DebugLoc when setting the insertion point to the end of a BasicBlock is long-standing and this change might have unexpected knock-on effects (although if we do make this change, it must also be extended to the setInsertPoint(BasicBlock*) version of this function to avoid a confusing difference). I think the more reasonable version of this change would be to save and restore the old debug location explicitly - the RAII version of this pattern, llvm::InsertPointGuard, has this behaviour. Updating the InsertPoint class and every consumer of its API would be onerous, but has less risk of introducing surprising results; modifying just the code that causes #147063 to save and restore a debug location would be preferable to this, at least imo. I'm open to changing my mind if there's a good argument that this behaviour is correct in principle, however.

I'm open to changing my mind if there's a good argument that this behaviour is correct in principle, however.

Thanks @SLTozer for your comments. I started fixing the individual cases which cause #147063 but then thought that it may be good to fix the problem in more general sense. Although I think the current behavior is not the right one but I do agree that it is long standing one and there may be dependency on this behavior in the clients. On the positive side, the adjustments required in testcases were quite small which indicates that dependency on this behavior may not be very deep (and the debug location in those testcases after this change look better imho).

The rationale for change was that if we are inserting at the end of a BB, the DebugLoc of the last instruction in that BB is better match then the DebugLoc of a random BB (which is some cases may not even be in the same function). May be the problem is absence of DebugLoc in InsertPoint which requires us to guess DebugLoc to use instead of it being part of InsertPoint like it is for llvm::InsertPointGuard.

This fixes llvm#147063. I tried to fix this issue in more general way in llvm#147091 but the reviewer suggested to fix the locations which are causing this issue. So this is a more targeted approach. The problem is that InsertPoint class does not hold the debug location. It is obtained from the instruction at the current position. But if the current position is at the end of the block, we just leave the debug location as is (see SetInsertPoint). We have 2 scenarios that we need to handle: In first situation, we have the location before hand and we can save the correct debug location. For example, in the following code, even if the line 3 does not end up setting the debug location, we can save it before line 1 and then restore it. This can be done either manually or using the llvm::InsertPointGuard as shown below. 1. auto curPos = builder.saveIP(); 2. builder.restoreIP(/* some new pos */); 3. builder.restoreIP(curPos); { llvm::InsertPointGuard IPG(builder); builder.restoreIP(/* some new pos */); } For the 2nd scenario, look at the code below. 1. void fn(InsertPointTy allocIP, InsertPointTy codegenIP) { 2. builder.setInsertPoint(allocIP); 3. // generate some alloca 4. builder.setInsertPoint(codegenIP); 5. } The fn can be called from anywhere and we can't assume the debug location of the builder is at the valid location. So if line 4 does not update the debug location because the codegenIP points at the end of the block, the rest of the code can end up using the debug location of the allocaIP. The solution here is to use the locaiton of the last instruction in that block for such case. I have added a wrapper function over restoreIP that could be called for such cases.
