Features

• Binary Size Regression Tracking - Isolates specific symbols or functions responsible for size regressions by comparing different binary versions.
• Debug Symbol Resolvers - Provides mechanisms to resolve symbols in stripped binaries using build identifiers and external debug information.
• Compilation Unit Profilers - Maps binary size back to specific source files by analyzing debug line information to identify bloated translation units.
• Stripped Binary Debugging Tools - Restores symbol and compile unit information for stripped binaries using external debug files and build IDs.
• Executable Format Support - Provides comprehensive parsing support for ELF, Mach-O, PE/COFF, and WebAssembly executable formats.
• Byte-Level Symbol Attribution - Maps every individual byte of a binary to a specific symbol or compile unit for precise size attribution.
• Binary Diffing - Compares two binary versions to identify structural changes and areas of size growth or shrinkage.
• Executable Format Analyzers - Parses binary and archive formats to analyze internal structure, including linker sections and memory segments.
• Binary Size Reporters - Provides utilities for calculating and displaying the total memory footprint and disk size of compiled programs.
• Multi-Format Binary Loaders - Implements loaders for ELF, Mach-O, PE/COFF, and WebAssembly formats to extract size and symbol data.
• Symbol Size Profilers - Measures and aggregates the memory footprint of individual binary symbols and sections into hierarchical reports.
• Inlining Analysis - Analyzes binary space consumed by inlined functions by correlating binary addresses with debug line information.
• Binary-to-Source Mapping - Associates binaries with source map files to enable compile unit and inline profiling.
• Symbol Aggregation Rules - Allows the creation of custom grouping rules using regular expressions to aggregate binary symbols or sections.
• Section Size Analysis - Reports the size of individual binary sections and segments across multiple executable formats.
• Linker Section Analysis - Groups binary data by linker sections to identify which atomic regions are consuming the most space.
• Memory Footprint Analysis - Distinguishes between the virtual memory footprint and the physical file size during binary analysis.
• Symbol Demanglers - Translates mangled C++ symbol names into human-readable formats to identify space-consuming functions.
• Object File Size Profiling - Breaks down the size of static libraries by analyzing the individual object files they contain.
• Segment Permission Analysis - Determines how memory is mapped with specific read, write, and execute permissions via runtime loader segments.
• Inlining Analysis - Identifies the amount of binary space consumed by inlined functions from header files using debug information.
• Hierarchical Reports - Generates nested reports that visualize the structural relationship between binary segments, sections, and symbols.
• Infrastructure and Configuration - Profiles binary size to identify bloat.
• Binary Analysis - Profiles binary size to understand what consumes space.
