2.8.1 Supported Macros

The c6x_migration.h migration header file redefines macros that were defined internally by the C6000 compiler toolchain. The definitions map to the appropriate C7000 definitions.

  • C6000 Target Macros: All of the following target macros map to __C7000__.
    • __TMS320C6X__
    • _TMS320C6X
  • C6000 Subtarget Macros: All of the following subtarget macros currently map to __C7100__.
    • _TMS320C6600
    • _TMS320C6740
    • _TMS320C6700_PLUS
    • _TMS320C67_PLUS
    • _TMS320C6700
    • _TMS320C64_PLUS
    • _TMS320C6400_PLUS
    • _TMS320C6400
  • Endian Macros: The following are deprecated. The C7000 compiler defines __big_endian__ or __little_endian__, which should be used instead.
    • _BIG_ENDIAN
    • _LITTLE_ENDIAN
  • EABI Macros: The following is deprecated. __TI_EABI__ should be used instead.
    • __TI_ELFABI__
