I've got a simpler testcase that seems to trigger the same ICE, if this is =
of
any help.

$ cat lra.c
int a, c;

void f(long long p)
{
    long long b;

    if(b)
        b =3D p ? : 0;

    for (; p; p++)
        p *=3D a & (c =3D p *=3D !a < 2);

    a =3D b +=3D !(b & 3740917449);
}

$ xgcc -O1 -m32 -w lra.c
lra.c: In function =E2=80=98f=E2=80=99:
lra.c:14:1: internal compiler error: in assign_by_spills, at lra-assigns.c:=
1217
 }
