sparse-llvm array size computation issue

[Dibyendu Majumdar <mobile@xxxxxxxxxxxxxxx>]

Hi,

I am investigating an issue with following test case:

int main(void)
{
const char *names[] = {
"dibyendu",
"majumdar",
NULL,
};
return 0;
}

The issue here is that sparse-llvm thinks the array size is zero:

define i32 @main() {
L0:
  %names_0000026DE9D2DDA8. = alloca [0 x i8*]

It appears that sparse is correctly calculating the size of the array
in examine_node_type() in symbol.c, but by the time the symbol gets to
sparse-llvm the bit_size is somehow changed to -1. I haven't yet
tracked down where this is happening.

Thanks and Regards
Dibyendu
