Rule 10.6: \"u\" Suffix to all unsigned constants

[Manni]

Hello

I have a disagreement with a supporter of a bigger MISRA-C:2004 rule checking tool.

He means, that the following is MISRA-C:2004 compliant :

Code:

void foo(UINT b)
{
UINT a;

a = b + 30;
}

I mean, it is not compliant . There must be \"u\"-Suffix:

Code:

void foo(UINT b)
{
UINT a;

a = b + 30[b]u[/b];
}

1. reason:
\"Rule 10.6 (required): A \"U\" suffix shall be applied to all constants of unsigned type.\"

I think, it is a clear case, when I read this rule. There is spoken from \"all\" constants of unsigned Type. So why there should be no \"u\" Suffix?




2. reason:

In \"Rule 10.1 (required):\" in MISRA-C:2004, are examples for this:

MISRA-C:2004 in Rule 10.1/10.2

Code:

... u8a + 5 /* not compliant */

... u8a + 5U /* compliant */

For me it is really a clear case, there must be a \"u\" suffix at the constant. But we need to clarify it, with an official answer for this tiny problem.

Thanks
