我会怀疑一个编译器错误。您正在使用什么编译器? 这个帖子提到编译器故障而导致米斯拉10.1采用TI公司的编译器时/ R故障。
The following code fails on a MISRA check. The concrete error message is:
(MISRA-C:2004 10.1/R) The value of an expression of integer type shall not be implicitly converted to a different underlying type if it is not a conversion to a wider integer type of the same signedness
typedef enum _MyEnum { One, Two } MyEnum;
MyEnum MyVariable;
int foo(void)
{
int result = 1;
if (One == MyVariable) // fails here with MISRA-C:2004 10.1/R
{
result = 2;
}
return result;
}
One
and MyVariable
?Edit: The compiler is a TI "MSP430 C/C++ Compiler v4.0.0" with included MISRA rules check.
I would suspect a compiler bug. What compiler are you using? This post mentions a compiler bug causing Misra 10.1/R failures when using TI's compiler.
