For the testcase:
/home/razya/mainline_new_3/gcc/gcc/testsuite/gcc.c-torture/execute/20021111-1.c,
when using fipa-cp, a new vfersion is created
for aim_callhandler(). the static variable is copied twice into the
unexpanded_var_list of the versioned function.
Looking at this test, even without enabling ipa-cp, the local variables
multiplies after inlining.(as shown in the dump below)
For example :
in 20021111-1.c.t23.alias1:
aim_callhandler (sess, conn, family, type)
{
int D.1449;
int sess;
int conn;
short unsigned int family;
short unsigned int type;
static int i = 0;
int D.1457;
int D.1456;
int i.0;
int D.1458;
int D.1449;
int D.1435;
int sess;
int conn;
short unsigned int family;
short unsigned int type;
static int i = 0;
int D.1443;
int D.1442;
int i.0;
int D.1444;
int D.1435;
int D.1421;
int sess;
int conn;
short unsigned int family;
short unsigned int type;
static int i = 0;
int D.1429;
int D.1428;
int i.0;
int D.1430;
int D.1421;
int D.1407;
int sess;
int conn;
short unsigned int family;
short unsigned int type;
static int i = 0;
int D.1415;
int D.1414;
int i.0;

try dumping with -fdump-tree-*-uid, they are probably different copies. You
can
try http://gcc.gnu.org/ml/gcc-patches/2005-08/msg00314.html to avoid having
unused versions dumped.

It doesn't help.
The decls are actually inserted to unexpanded_var_list more than once by the
inliner. Thanks.
