MapView is a powerful linker map file analyzer and visualizer designed for embedded systems developers, firmware engineers, and anyone working with compiled binaries who needs to understand memory usage and optimize their code size. Now with experimental support for parsing ELF files. MapView also includes a command-line interface (CLI) tool for automated analysis and CSV export. To start the CLI version call mapview_cli from powershell or cmd. Mapview supports map files from the following compilers: * GCC / Binutils (ld map files) * GCC ARM (hosted) 5.4.0 - 15.2.0 * GCC ARM64 (hosted) 4.9.4 - 15.2.0 * GCC x86 (hosted) 5.5.0 - 15.2.0 * GCC HPPA (hosted) 14.2.0 - 15.2.0 * GCC LoongArch64, MIPS, PowerPC, RISC-V 32/64, S390x, Sparc (GCC 15.2.0) * GCC ARM bare-metal (arm-none-eabi) 7-2017-q4 - 14.3.Rel1 * GCC ARM bare-metal (arm-unknown) 13.2.0 - 15.2.0 * Intel oneAPI DPC++/C++ Compiler 2025.3 * Clang (LLD linker, x86-64 Linux) 3.2 - 22.1 * Microchip (hosted) MPLAB XC and C30 * IAR (hosted) 6.50 - 8.22 - experimental * ARM Compiler (hosted) 5.03 - 6.24 - experimental * MSVC (Microsoft Visual C++ map files) - experimental * ELF binaries (with DWARF debug info) - experimental Supported languages: * English * Čeština * Dansk * Deutsch * Ελληνικά * Español * Suomi * Français * Magyar * Italiano * Norsk * Nederlands * Polski * Português * Română * Svenska Note: Experimental parsers may not support all features.
