CODECOMPOSER: Bug report: Warning False positive when variable is set in function call.

Hi George,

Thanks for answer.

Considering your example, I can see why the compiler would generate this warning.

I'm raising this issue because this behavior is, as far as I can tell, unusual.

As you can see, we don't see this behavior in the 3 major compilers gcc, clang and msvc:

godbolt.org/.../c9q9eqMvz

Having the TI compiler behave differently can cause frictions, in my opinion. 

Regards,

Gabriel

I respect your opinion.  

At the same time, the handling of compiler diagnostics is not specified in the language standards. That is why the TI Arm compiler supports methods to control many (not all) diagnostics.  This particular diagnostic is among those you can control.  For instance, it can be suppressed with the option --diag_suppress=552.  For details, including yet other methods, please search the TI ARM compiler manual for the sub-chapter titled Understanding Diagnostic Messages.

Thanks and regards,

-George

Ok that make sense. Regarding suppressing the warning, I don't think I want to do that, as it can be useful.

From now on, I will considerer this issue as a "feature request" instead of a "bug reports" .

I can also close it as "resolved" if you wish.

Make sense.

Thanks for your suggestion. I don't think the new compiler supports the TI Hercules series of MCU.
