Der Wind River Compiler besteht aus folgenen Komponenten:

• Driver: Intelligent wrapper program invokes the compiler, assembler, and linker
• Assembler: Macro assembler invoked automatically by the driver program or as a complete standalone assembler generating object modules; includes the following key features:
  • Conditional macro assembler with more than 30 directives
  • Unlimited number of symbols
  • Debug information for source-level debugging of assembly programs
• Linker: Precisely controls allocation, placement, and alignment of code and data; includes the following key features:
  • Links object modules into absolute or relocatable modules
  • Reads/writes/mixes ELF and COFF object file
  • Generates fully EABI-compliant ELF/DWARF output for tool interoperability
• Libraries
  
  • Complete reentrant C libraries compliant with ANSI/ISO, POSIX, and SVID standards
  • Complete C++ library (STL)
  • Full complement of math libraries, including IEEE-754 appendix functions
  • Fast, efficient floating-point libraries
  • Library source code
• Archiver/librarian: Creates and maintains libraries
• Instruction set simulator: Simulates the core instructions of the target processor and allows it to run C and C++ programs with the simulated environment
• Profiler: Profiling options instrument application code that when executed saves profile information for viewing by the profiler. Profile data can also be automatically fed back to the compiler for additional code optimization based on execution path
• Object file converter: Provides conversion routines for generating S-Record or IEEE-695 output formats and also provides the following:
  • Symbol table management
  • Detailed code size reports
  • C++ symbol name demangler
  • Munch routine
• Documentation: Wind River Compiler includes extensive documentation specific to the chosen architecture, with all manuals available in PDF formats; a detailed “Getting Started” manual enables users to get up to speed quickly and enhances the out-of-the-box experience
