Description Andrew Pinski 2004-06-06 01:22:43 UTC 
struct a{int i;};
static const struct  a b = {1};
int g(){return b.i;}

This should be optimized to just
int g(){return 1;}

Confirmed with mainline of today. A case for scalarization.

mine
Comment 4 Steven Bosscher 2004-08-31 21:01:02 UTC 
simple patch not good enough, and no clue how to 
handle "x = a.b.c.d.e[2].f[4].g"
