Compile the following with -O2 --param calls-threshold-global-var=0 .
(Note, this --param was added on 2004-01-19 to enable easier reporting of bugs dependent on
GLOBAL_VAR; the original is sixtrack in SPEC2000).
Observe the ICE beginning:
small2.c:3: error: Missing definition
for SSA_NAME: i_12
in statement:
i_1 = PHI <i_12(0), i_33(1)>;
This used to work, and was apparently introduced sometime in early January.
===========================
extern void __Bar (char *, int, char *, int);
static char bez0[11200];
int foo () {
static int i;
static int irecuin;
static char iqq[80];
static char iss[32];
irecuin = 0;
__Bar (&iss[0],16,"",1);
__Bar (&iss[16],16,"",1);
for ( i=1; i<=5; i++)
__Bar (&iqq[(i-1)*16],16,"",1);
for ( i=1; i<=5; i++)
__Bar (&bez0[(i-1)*16],16,"",1);
Bax(&irecuin);
}

Dale, can you still reproduce this with version 3.5-tree-ssa 20040203? I haven't
been able to.

It still fails for me with a top-of-tree-ssa-branch checkout
as of 3 Feb 14:16 (PST).
