rui314/mold: README-based editorial guide

rui314/mold describes itself in the README as "mold: A Modern Linker 🦠". This article keeps to facts that can be checked in the repository. Stars, forks, and promotional badges are signals of attention, not proof of quality. Under "mold: A Modern Linker", the README says: mold is a faster drop-in replacement for existing Unix linkers. It is several times quicker than the LLVM lld linker, the second-fastest open-source linker, which I initially developed a few years ago.. That establishes the project's stated boundary, not a production test.

The README's "How to use" section gives a useful starting point for deciding whether the project fits: For GCC before 12.1.0: the -fuse-ld option does not accept mold as a. If that problem is not yours, popularity is a poor reason to adopt it. Project names, commands, and component names are kept as written so a reader can return to the primary source without guessing at terminology. Another checkable README item is: For GCC before 12.1.0: the -fuse-ld option does not accept mold as a. It can shape a first test, but it does not replace testing in the intended environment.

The operating model is spread across sections such as "mold: A Modern Linker". The source evidence includes: | Program (linker output size) | GNU ld | GNU gold | LLVM lld | mold |-------------------------------|--------|----------|----------|------ | MySQL 8.3 (0.47 GiB) | 10.84s | 7.47s | 1.64s | 0.46s | Clang 19 (1.56 GiB) | 42.07s | 33.13s | 5.. This article does not turn missing architecture, performance, or security details into claims. A real deployment still needs a look at the repository layout, configuration files, and release history.

Start installation from the README's documented entry point. A command that can be checked in the source is: git clone --branch stable https://github.com/rui314/mold.git cd mold sudo ./install-build-deps.sh cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_CXX_COMPILER=c++ -B build cmake --build build -j$(nproc) sudo cmake --build build --target install When the README contains no runnable command, this article does not invent one. Open its "Why does linking speed matter?" section and confirm system dependencies, default ports, and first-run initialization before using a public server.
