LLVM 21.1.0, released on August 26, introduces the AMD GFX1250 target, enhancements to the AMDGPU backend, support for NVIDIA GB10 CPUs, RISC‑V improvements, and LLDB debugger upgrades, and is freely available for download from the official GitHub releases page.
This article introduces the fundamentals of source-level debugging for WebAssembly, explains core debugging principles, discusses native and managed program debugging, examines various debugging information formats such as SourceMap and DWARF, and compares several practical debugging solutions—including Chrome DevTools, LLDB with wasmtime or iwasm, and WasmInspect.
This article describes a comprehensive LLDB‑plugin based monitoring framework that intercepts Xcode’s Script Bridge API to measure and report precise debugging latency for Swift projects, outlines the implementation details, timing scenarios, data reporting, and includes a recruitment notice for the ByteDance client infrastructure team.
This article explains why C/C++ binaries become black boxes on mobile platforms, how to inspect DWARF debug information, and provides step‑by‑step LLDB commands and a Python‑driven lldbinit script to automatically map remote source paths for seamless debugging on iOS and Android.
This article explains how ByteDance's DanceCC team improved debugging speed for large Swift iOS projects by customizing the LLDB toolchain, disabling costly Swift type‑resolution features, fixing static‑framework loading, optimizing external module searches, and introducing shared symbol caches, achieving up to ten‑fold reductions in variable‑view and expression‑evaluation times.
The Youku iOS team investigated why first‑breakpoint pauses could exceed three minutes after a massive Swift migration, analyzed LLDB internals and external module dependencies, tried and discarded several refactoring and compiler‑flag approaches, and finally achieved a dramatic speedup by tweaking LLDB settings and adding a small Swift helper for missing property prints.
LLDB is a high‑performance debugger integrated with Xcode that supports C, Objective‑C, and C++ development; this article introduces its command‑line syntax, explains key commands such as help, expression, thread, breakpoint, watchpoint, and image, and provides usage examples to improve debugging efficiency.
This guide explains how to configure Android Studio and LLDB to perform native debugging of the Dalvik virtual machine on Android devices, covering both scenarios with and without app source code, required environment setup, useful LLDB commands, and step‑by‑step procedures for remote debugging.
This article explains how iOS developers can retrieve crash logs from simulators, test devices, and App Store releases, then use LLDB and custom crashlog scripts to symbolicate, inspect stack traces, and resolve hard‑to‑reproduce crashes caused by memory‑management issues such as over‑release.
This article introduces the most commonly used LLDB commands for iOS development, covering command syntax, help utilities, expression evaluation, printing, thread management, breakpoints, and watchpoints, and provides practical code examples to improve debugging efficiency in Xcode.
This article explains how iOS developers can use Xcode's breakpoint features—including basic toggles, conditional breakpoints, ignore counts, actions like LLDB commands and log messages, exception breakpoints, and symbolic breakpoints—to pause execution, inspect state, and streamline debugging workflows.
This guide introduces the open‑source LLDB debugger and the Facebook‑maintained Chisel plugin for iOS, covering installation via Homebrew, configuration of .lldbinit, and a comprehensive set of custom commands that simplify UI inspection, view hierarchy analysis, and autolayout debugging within Xcode.
Learn how to efficiently debug MySQL source code on macOS using Visual Studio Code and LLDB, covering installation of LLDB via Homebrew, configuring VS Code extensions, setting up local and remote debugging parameters, breakpoint management, and essential command-line steps for seamless development.
