...are the steps I propose to implement the feature. 1. Define debug metadata and intrinsic functions for labels. First of all, we need to record debug information in LLVM IR. In LLVM IR, LLVM uses metadata and intrinsic function to keep debug information. So, I need to define new kind of metadata, DILabel, and new intrinsic function, llvm.dbg.label, to associate DILabel with label statement. DILabel will contain name of the label, file metadata, line number, and scope metadata. Intrinsic function llvm.dbg.label uses DILabel metadata as its parameter. 2. Create MI instruction DBG_LABEL. I create...

When the basic block is inlined it will be ambiguous to which function the DILabel belongs. For instructions, we store the inline information in the inlinedAt: field of its DILocation. In order to handle inlining for DILabels we have two options: 1. Also attach a DILocation to b...

Hi, I try to use llvm-dis to disassemble the result after opt, my pass will add a intrinsic after the load instruction, like following: bool fpscan::ldAddMetadata (Instruction *Inst, StringRef c) { std::vector<Metadata *> dataTuples; // Add metadata in list dataTuples.push_back(MDString::get(Inst->getContext(), c)); MDNode* N = MDNode::get(Inst->getContext(),

...nity of merging offsets into the generated load/store instructions. [r332015](https://reviews.llvm.org/rL332015). * An initial version of the llvm-strip tool was introduced. This is ultimately intended to be a drop-in replacement for binutils strip. [r331663](https://reviews.llvm.org/rL331663). * DILabel metadata and the llvm.dbg.label intrinsic have been introduced to LLVM. These allow debug info on labels to be emitted, which ultimately enables debuggers to set breakpoints on labels. [r331841](https://reviews.llvm.org/rL331841). * HexagonMCCodeEmitter was refactored to use data tables to handle...
