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 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. CodeView Reader - Support for CodeView/PDB.
