This article explains how the size of a Rust‑based Android dynamic library, initially 495 KB, was dramatically reduced to 95 KB through compiler optimization levels, link‑time optimization, panic handling changes, stripping unused sections, and custom linker scripts, providing practical tips for mobile developers.
This article details how the author reduced the size of a Rust‑based Android JNI dynamic library from 495 KB to 95 KB by adjusting compiler optimization levels, enabling LTO, switching panic handling to abort, removing unused strings, applying panic_immediate_abort, and crafting a custom linker script, while providing code snippets and size comparison tables.
This article details Tongcheng Travel's comprehensive iOS app slimming process, covering background importance, size‑reduction techniques, multi‑dimensional analysis, Python‑based detection scripts, compiler LTO optimization, resource governance, platform automation, and the resulting 29% package size decrease that boosted download conversion.
The article details Baidu APP’s comprehensive compiler‑optimization strategy, including GCC‑Oz size reduction, Swift‑Osize with whole‑module optimization, link‑time optimization, symbol stripping, dead‑code removal, asset catalog compression, minimizing C++ virtual functions, slimming third‑party SDKs, dropping unused ARM architectures, Xcode 14 binary‑size tweaks, and eliminating built‑in Swift libraries by raising the minimum iOS version.
This article details Baidu APP’s iOS package‑size optimization series, focusing on compiler tweaks (GCC, Swift, LTO, symbol stripping, dead‑code removal, asset catalog settings, C++ virtual‑function reduction, third‑party SDK slimming), instruction‑set pruning, Xcode‑14 improvements, and Swift dynamic‑library handling, together with concrete Xcode configuration steps and measured size gains.
This article explains how Meituan engineers shrink Android native .so libraries by analyzing ELF sections, simplifying dynamic symbols, removing dead code, using link‑time optimization, garbage‑collecting sections, applying size‑focused compiler flags, disabling exceptions/RTTI, and merging or extracting libraries, achieving 30‑60% APK size reductions and faster load times.
The article details OMAX’s end‑to‑end platform for large‑scale C/C++ service compilation, covering optimization flags, profile‑guided and link‑time techniques, Facebook BOLT post‑link tuning, and real‑world results that cut CPU use, latency and deployment time while shrinking binary size.
After a week-long delay, Linus Torvalds announced the official release of Linux kernel 5.12, highlighting support for Intel Xe GPU variable refresh rates, C language link‑time optimization (LTO), kernel fencing (KFENCE), and overclock profiles for AMD Radeon RX 6000 series, while noting it’s a modest update ahead of the larger 5.13.
