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.
