Current mainline (revision 127590) still gets this ICE for i686-pc-linux-gnu
with either bid or dpd decimal float support. The current line number for the
ICE is reload1.c:2001.

The following test case is miscompiled with GCC 4.2:
extern void abort (void);
volatile int N = 5;
void foo (void)
{
int i;
char *p, value[10];
value[0] = 0x42;
for (i = 0; i N; i++)
if (i 0)
{
p = (char *)i - 1;
*(value + (int) p) = (char) i;
}

Oh you are correct but this still worked in 4.1.1 though, I have not looked
into what changed between 4.1.1 and 4.2.0 with respect of scev yet.

The IR is the same but scev did something different:
Visiting statement:
p_10 = i.0_9 - 1B;
(analyze_scalar_evolution
(loop_nb = 1)
(scalar = p_10)
(get_scalar_evolution
(scalar = p_10)

Why use %.9e, %.17e, and %.36Le to write the binary float values to a
string, instead of using lengths of FLT_DIG, DBL_DIG, and LDBL_DIG? For
i686-linux those are 6, 15, and 18.
