Modify dwarf verification JSON to include detailed counts by sub-category (#128018) To help make better use of dwarfdump verification for identifying and fixing issues with debug information, the JSON will now emit details (sub-categories) where relevant. First modification concerns missing tags as those were recently missing for BOLT debug names. Test: test files for JSON output were previously added, so modify here to expect the new JSON keys. One test has sub-categories and another is empty. ninja check-llvm-tools-llvm-dwarfdump Also build the tool and run with a local executable to verify. ninja llvm-dwarfdump
Welcome to the LLVM project!
This repository contains the source code for LLVM, a toolkit for the construction of highly optimized compilers, optimizers, and run-time environments.
The LLVM project has multiple components. The core of the project is itself called “LLVM”. This contains all of the tools, libraries, and header files needed to process intermediate representations and convert them into object files. Tools include an assembler, disassembler, bitcode analyzer, and bitcode optimizer.
C-like languages use the Clang frontend. This component compiles C, C++, Objective-C, and Objective-C++ code into LLVM bitcode -- and from there into object files, using LLVM.
Other components include: the libc++ C++ standard library, the LLD linker, and more.
Consult the Getting Started with LLVM page for information on building and running LLVM.
