The file shows the symbols and sections contained in a binary. The linker also provides the memory address and size for each symbol. \n\nThe map files are usually text files, where in most cases each line represents a symbol with its size and position in memory. In many cases the symbols are arranged alphabetically in the file, for example:\n\n```\n_dspCol                0x000005c2     0x1  Data  Gb  display.o [1]\n_dspDataIdx            0x000005b0     0x2  Data  Gb  spi0.o [1]\n_dspDataLen            0x000005b2     0x2  Data  Gb  spi0.o [1]\n_dspFont               0x000005c3     0x1  Data  Gb  display.o [1]\n_dspGoto               0xfffa417d    0x13  Code  Gb  display.o [1]\n_dspHLine              0xfffa411b    0x62  Code  Gb  display.o [1]\n_dspInit               0xfffa4875   0x22b  Code  Gb  display.o [1]\n_dspIntCol             0x000005c0     0x1  Data  Gb  display.o [1]\n```\n\n## What is mapalizer\n\nMapalizer interprets the map files and extracts all information about symbols. This information is presented in a clear manner, giving the user a better overview of the memory organization.\n\nThe user has the option to:\n- sort the symbols by name, address, size, type and section.\n- filter the symbols by section.\n- search a symbol by name.\n\nMapalizer can help you:\n- identify the potential location of buffer overflows (by checking how the symbols are organized in memory).\n- identify the most memory-expensive symbols and their sections.\n- identify all memory used (or available) for data and code.\n\nThe following compilers/linkers are supported: IAR, Keil\n\n## How to compile mapalizer\n\nmapalizer was created in Qt5 + Microsoft Visual C\n\n## How to run mapalizer\n\nWindows: download the `bin/mapalizer.exe` and execute it.\n(MD5 Checksum: 044b9e6aaf42896c469b1e1442c08e8f)\n\n## To do\n\n- Add support for more compilers/linkers.\n- Add support for other platforms.\n- Add CSV export/import.\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Figor-marinescu%2Fmapalizer","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Figor-marinescu%2Fmapalizer","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Figor-marinescu%2Fmapalizer/lists"}
