But note that there is no issue with -fsanitize=undefined on
return i - (-4096);
So the cause is the transformation of i + 4096 to i - (-4096).

For i + 4095:
add %g1, 4095, %g1
For i + 4096:
sub %g1, -4096, %g1
For i + 4097:
sethi %hi(4195328), %g1
srlx%g1, 10, %g1
add %g2, %g1, %g1

Not sure how useful this is but all of the following toss the same ICE :
long f(long arg){return arg + 4096;}
long f(long arg){return arg - 4096;}
long f(long arg){return 4096 + arg;}
