llvm-debuginfo-analyzer is a command line tool that processes debug info contained in a binary file and produces a debug information format agnostic “Logical View”, which is a high-level semantic representation of the debug info, independent of the low-level format. The code has been divided into the following patches: 1) Interval tree 2) Driver and documentation 3) Logical elements 4) Locations and ranges 5) Select elements 6) Warning and internal options 7) Compare elements 8) ELF Reader 8a) Memory Management 9) CodeView Reader Full details: https://discourse.llvm.org/t/llvm-dev-rfc-llvm-dva-debug-information-visual-analyzer/62570 This patch: This is a high level summary of the changes in this patch. Memory Management - Use Bump allocators for memory management. As the logical elements are only allocated in one pass (debuginfo parsing) and they are never manipulated/created/destroyed later, use the SpecificBumpPtrAllocator for the memory management.
