Works when linking in comm.o main.o order.
FWIW one can construct test cases where neither order works, e.g.,
cat main.c \EOF
extern int i;
int j;
int main(void)
{
i = 0;
return i;

Cary, can you give advice and/or fix gold and/or the linker plugin?

It works with the llvm plugin for gold. I also find the gold output funny. What
the llvm plugin does is
if (I-syms[i].resolution == LDPR_PREVAILING_DEF ||
(I-syms[i].def == LDPK_COMMON

The llvm change is
http://llvm.org/viewvc/llvm-project?view=revrevision=64616
so I still don't know why gold is not returning LDPR_PREVAILING_DEF for the
common symbol definition.

Works when linking in comm.o main.o order. I guess the linker
resolution handling is bogus.

I see
2
main.o 2
78 PREVAILING_DEF main
81 RESOLVED_IR i
comm.o 1
78 RESOLVED_IR i
which is obviously bogus for comm.o.
