Shift-by-signext - sext is bad for analysis - ignore it's use count?
...%o1 = sub i32 32, %o0
%r = shl i32 %5, %o1
While
int shl1(int x, unsigned char y) {
return x << (32 - y);
}
produces
%n0 = zext i8 %6 to i32
%n1 = sub i32 32, %n0
%r = shl i32 %5, %n1
(as one would expect)
And here we again don't need sign-extension:

In my eyes, that doesn't completely invalidate

i still think it is a good idea, but clearly we *also* need
something else, more generic.
My first thought would be CVP and LVI, but i did not look yet..

OT: question on setting up an email server
Hi guys,
I realize that this might be considered to be off topic, but the
machine I want to use is running Cent OS.
Ok, this is what I'm thinking about trying, and mainly just to see
if I can do it. I've got a total of 3 linux machines here, and I was
thinking about setting one of them up as an email server. Now, I'm not
talking about setting the machine up so that all I

The thing is, we *don't* "not demand" those high bits.
We *don't* not care what's in those bits - IR shifts don't mask their
shift amounts.
I.e we can't replace `x >> (32-y)` with `x >> (-y)`,
which would be legal transform should we not demand those bits.
We very much demand them. We just know those bits to be zero.
And i'm not sure how to convey
