[cfe-dev] use of 'restrict' pointer

[Arvind Sudarsanam]

Hi,

 

I have C source code which qualifies some of the pointers using the
'restrict' keyword and used clang to generate the llvm IR code.

Here is the C source code:

 

int restrict1(void)

{

            int* restrict a;

            int* restrict b;

            int x[10];

            int y[10];

            

            *a = x[2];

            *b = x[3];

            return(x[4]);

}

 

The 'restrict' information seems to be lost in the generated IR code. Am
I doing something wrong here?

 

Thanks

Arvind
