We get the following ICE on alpha with 4.1 and 4.2. gcc 4.0 works.

------- Comment #2 from falk at debian dot org 2006-08-10 21:11 -------
Confirmed. This is a smaller test case:
int vformat(char *buffer) {
return buffer[32767];
}
This needs -mcpu=ev45. It is triggered by the synthetization
of the 8-bit load by 64-bit loads. ldb v0, x(a0) is done as
lda a0,x+1(a0)
ldq_u v0,-1(a0)
extqh v0,a0,v0
sra v0,56,v0
and if x=32767, this fails.
(Incidentally, maybe we should do
ldq_u t1,x(a0)
lda a0,x+1(a0)
extqh t1,a0,t1
sra t1,56,v0
and save one cycle at the cost of one extra register.)

Alpha is not a primary or secondary platform.
