Implementation Defined C90 and C99 behavior section is missing from spnu151.pdf

The TI compilers officially support only C89 although some features of C90 and C99 are provided as language extensions. Implementation defined behavior is described in Chapter 5 (ARM C/C++ Language Implementation) of the TMS470 Compiler Users Guide.

This wii article is also a good reference: http://processors.wiki.ti.com/index.php/TI_Compilers_and_Industry_Standards

Hello Aarti,

I looked into Chapter 5. Not asingle section mentons about the IMPLEMENTATION DEFINED parts of C89.

For example, accoding to C89, for SIGNED INTEGER RIGHT SHIFT, it can be either Arithmetic Right Shift or Logical Right Shift. That is IMPLEMENTATION SPECIFIC according to C89.

Can you please tell me which section of spnu151 defines the above mentioned implementation defined characteristic?

Thank you.

Regards

Pashan

Although that chapter is not explicitly titled "Implementation Defined" there are several aspects of implementation defined behavior described there. I agree with you that the implementation of signed integer right shift is not mentioned there. I will try to get you an answer on this.
