CMC (CodeMaster C Compiler) generates extremely compact code for Cortex-M devices!

• Supports the ARM7, ARM9, Cortex-M0, Cortex-M1, Cortex-M3 and Cortex-M4 microcontrollers. See the device list
• Sold as a CodeMaster-ARM IDE license or as a stand alone CMC licence to be used with third parties' IDEs
• Free 30 days trial - download a fully functional CodeMaster IDE with the compiler and simulator. Buy on-line.

• Efficient support for ARM/Thumb mode switching
• Mixing ARM and Thumb code in the same source file
• Libraries for all the modes, including the interworking mode

• Full conformity to ANSI/ISO 9899-1990 standard
• Some extensions conforming to the ISO 9899-1999 standard, in particular:
  • C++ stile comments
  • Macros with variable number of arguments
  • Syntax of enumerations and initializer lists
• Special extensions for embedded software development:
  • Binary constants
  • Automatic calls of special functions in prologue/epilogue
  • Assigning variables to absolute addresses
  • Control for static variables initialization
• Platform-dependent extensions for implementation of the:
  • Interrupt handlers
  • Monitor functions
• Set of intrinsic functions providing access to low-level processor resources and generation of special instructions
• Built-in inline assembler

• Generates extremely compact and fast executing code
• Significantly more compact code than one generated by the GCC GCC compiler
• Allowed optimizations include (but not limited to):
  • Efficient allocation of local and temporary variables
  • Optimization of high-level intermediate representation
  • Platform-dependent low-level optimizations

• Standard C library (free-standing implementation)
• IEEE-754 compliant single and double precision floating-point arithmetic library
• Header files with description of special function registers of most popular target microcontrollers

• Allows assigning C types to variables and functions
• Supports conditional assembly
• Provides strict operand type checking
• Includes extensive set of 32-bit arithmetic and logical operators
• Supports local names (labels) in functions and macros
• Powerful macro capabilities
• Easy and safe integration with the compiler and CodeMaster debuggers

• EABI support, in particular:
  • Placement of base and aggregate data types
  • Convention on registers and stack usage
  • Calling convention
  • Operations with volatile objects
• Generation of ELF/DWARF output format
• CMSIS support
• Support of some non-standard C language extensions implemented by leading compiler manufacturers
• Extended symbol information for source code debugging

• Intended to be used by third parties in their IDEs.
• Includes:
  • Executable files of the CMC compiler, CMA assembler and CMLINK linker
  • Include files
  • Libraries
  • User's guides and integration guidelines
  • Stand alone license manager and updater
• Can be executed in the command line mode or launced from the IDE
• Subject of an OEM agreement between Phyton and an integrater
