sparse-llvm duplicate declarations of data

[Dibyendu Majumdar <mobile@xxxxxxxxxxxxxxx>]

Hi,

In the following test case:

static int once;
static int once = 1;
extern int printf(const char *, ...);
static int value(int *p)
{
 return *p;
}
int main(void)
{
 return value(&once) == 1 ? 0 : 1;
}

Sparse-llvm declares the global 'once' twice as there is a check
missing on whether the global has already been defined.

Regards
