From a35e2be4724a9c517fd4ead83ca9f47e44a70cea Mon Sep 17 00:00:00 2001 From: Abid Qadeer Date: Mon, 14 Jul 2025 17:17:09 +0100 Subject: [PATCH] [OMPIRBuilder] Don't drop debug loc from LocationDescription. LocationDescription contains both the instruction pointer and the debug location. When LocationDescription is available, it is better to use updateToLocation which will update both then restoreIP(Loc.IP) which may not. I am not checking the return value of updateToLocation because that is checked just a few lines above in all cases and we would have returned early if it failed. --- llvm/lib/Frontend/OpenMP/OMPIRBuilder.cpp | 7 +++---- 1 file changed, 3 insertions(+), 4 deletions(-) diff --git a/llvm/lib/Frontend/OpenMP/OMPIRBuilder.cpp b/llvm/lib/Frontend/OpenMP/OMPIRBuilder.cpp index 170224616ac64..cbae2e33cbc30 100644 --- a/llvm/lib/Frontend/OpenMP/OMPIRBuilder.cpp +++ b/llvm/lib/Frontend/OpenMP/OMPIRBuilder.cpp @@ -1161,7 +1161,7 @@ OpenMPIRBuilder::InsertPointTy OpenMPIRBuilder::emitTargetKernel( Builder.restoreIP(AllocaIP); auto *KernelArgsPtr = Builder.CreateAlloca(OpenMPIRBuilder::KernelArgs, nullptr, "kernel_args"); - Builder.restoreIP(Loc.IP); + updateToLocation(Loc); for (unsigned I = 0, Size = KernelArgs.size(); I != Size; ++I) { llvm::Value *Arg = @@ -1189,7 +1189,6 @@ OpenMPIRBuilder::InsertPointOrErrorTy OpenMPIRBuilder::emitKernelLaunch( if (!updateToLocation(Loc)) return Loc.IP; - Builder.restoreIP(Loc.IP); // On top of the arrays that were filled up, the target offloading call // takes as arguments the device id as well as the host pointer.
