Portability Analyzer — New

Instead of regex-based checks, this uses a compiler IR (e.g., LLVM IR, WASM) to detect:

Yocto/Buildroot users now run portability-analyzer new against their SDK. It detects endianness mismatches (PowerPC vs ARM), alignment traps, and Linux kernel CONFIG options missing in the target defconfig. Instead of regex-based checks, this uses a compiler IR (e

One of the "new" features gaining traction is modularity. Previously, buying a portable analyzer meant committing to one gas type (e.g., O2 only). New models feature hot-swappable electrochemical or NDIR (Non-Dispersive Infrared) cartridges. A technician can measure CO2 in the morning, swap to H2S for a landfill project in the afternoon, and switch to refrigerant leak detection by evening.

For decades, software portability has been a holy grail. The classic tools—autotools, CMake find_package, or Java’s “WORA” (Write Once, Run Anywhere)—were reactive. They told you at compile time if something was missing. The old guard of portability analyzers (e.g., ldd, depends.exe, scanelf) answered one question: “Does this binary have unresolved symbols?”

The new generation of portability analyzers answers a far more valuable question: “Given this source code or container, what will break on Target X before you spend CPU cycles building it?”

We are witnessing a shift from static dependency checkers to semantic and environmental predictive engines.
