[Icc-avr] How to get rid of Warning 'Illegal storage class const '

[Ivan Vernot]

Hello All,

I have just upgraded to latest ICCAVR 7.16A and am faced with 'upgrading' my
code to take into account the new __flash keyword

 

To get something compiling I enabled 'Treat 'const' as '_flash' option in
Complier options but I get the following warnings never-the-less.

 

!W
D:\Real_Time_Designs\Clients\CathRx\3DREMO~1\Source\usart128.h(122):[warning
] Illegal storage class const for parameter 'data'. Storage class removed.



Complains about the following function prototype 

extern void     USART1_cputch(const INT8U data);

 

and similarly 

!W
D:\Real_Time_Designs\Clients\CathRx\3DREMO~1\Source\usart128.c(124):[warning
] Illegal storage class const for parameter 'data'. Storage class removed.

 

Complains about the function

void USART1_cputch(const INT8U data)

{

}

 

1.     How do I stop it complaining about code that compiled without warning
previously?

2.     Is it safe to ignore these warnings?

3.     Is there anything documented/discussed as to a possible strategy to
upgrade existing code?

 

Thank you in advance

Ivan Vernot
