Hi,

I guess that diag_printf can't handle long long type of integers, at least
as far as with the gcc for 32 bit mips.
Below is the program to prove it.

#include <cyg/infra/diag.h>     // diag_printf
#include <stdio.h>              // printf
void cyg_user_start(void)
{
        unsigned long t1=0xaa00aa00;
        unsigned long long t2=0x22002200bb00bb00;
        unsigned long long t3=0x33003300cc00cc00;

        diag_printf("diag : t1:%16lx t1:%16llx t3:%16llx\n",t1,t2,t3);
        printf("stdio: t1:%16lx t1:%16llx t3:%16llx\n",t1,t2,t3);
        diag_printf("diag : t2:%16llx t1:%16lx t3:%16llx\n",t2,t1,t3);
        printf("stdio: t2:%16llx t1:%16lx t3:%16llx\n",t2,t1,t3);
        diag_printf("diag : t2:%16llx t3:%16llx t1:%16lx\n",t2,t3,t1);
        printf("stdio: t2:%16llx t3:%16llx t1:%16lx\n",t2,t3,t1);
	for(;;);
}

The attachment is my patch for this problem. I think this works with
32-bit compiler. But I suspect it does so with 64 bit compiler.
If you find anything or have better idea, please suggest me. 

Thank you in advance.
