[Bug lto/40902] New: LTO doesn't merge CV differences properly

Wed, 29 Jul 2009 06:36:40 -0700 

>From 464.h264ref we can see that for

t1.c
const int i[10] = { 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 };

t2.c
extern int i[10];
int main () { return i[0]; }

we should merge both decls, retaining the const qualification (the middle-end
considers both types compatible, lto_symtab_compatible doesn't).
