TI Compilers and Industry Standards
Contents
Programming Language Standards[edit]
C standard[edit]
The TI compilers for all devices support
- C89 (ISO/IEC 9899:1990, also known as ANSI X3.159-1989)
- C99 (ISO/IEC 9899:1999). C99 support is incomplete.
The TI compiler does not support
- C11 (ISO/IEC 9899:2011)
See those links for details of the implementation and variations from the standard.
C++ standard[edit]
The TI compilers for ARM and MSP devices now support
The other targets do not yet support C++11 or C++14. They support:
- C++98 (ISO/IEC 14882:1998)
- C++03 (this is a bug fix update to C++98)
These other targets do not support
- C++ TR1
- C++11 (ISO/IEC 14882:2011)
- C++14 (ISO/IEC 14882:2014)
See those links for details of the implementation and variations from the standard.
Validation[edit]
TI performs extensive regression validation tests to ensure that the compiler generates correct programs for conforming C and C++ code.
IEEE 754[edit]
The TI ARM and C6000 C/C++ Compilers support 32-bit and 64-bit format binary floating point numbers conformant to that part of IEEE-754 (ISO/IEC/IEEE 60559) available in C89 features, with the following caveats:
- Only when using a device that natively supports floating-point arithmetic
- The --fp_mode=strict option must be specified
- The --fp_reassoc=off option must be specified
- Only one NaN, qNaN (quiet NaN) is supported
- Only "round to nearest/even" mode is supported
- The compiler may perform optimizations which do not preserve the floating-point exception behavior at run time
See IEEE 754 Support in TI Compilers for more details.
MISRA-C[edit]
The compiler provides options to check for select MISRA-C rules. See the C/C++ Compiler User's Guide for your target.
Other industry standards[edit]
Additional industry specific tests such as IEC61508 safety tests, automotive TÜV safety tests are the responsibility of the user.
