Unfolded additions of constants after promotion of @llvm.ctlz.i16 on SystemZ
Hi,
SystemZ supports @llvm.ctlz.i64() natively with a single instruction
(FLOGR), and lesser bitwidth versions of the intrinsic are promoted to i64.
For some reason, this leads to unfolded additions of constants as shown
below:
This function:
define i16 @fun(i16 %arg) {
%1 = tail call i16 @llvm.ctlz.i16(i16 %arg, i1 false)
ret i16 %1
}
,gives this optimized DAG as input to instruction

[3.7 Release] Let's fix the release notes!
Dear everyone,
The in-progress release notes for 3.7 [1,2] make it look like we
didn't do very much over the past six months. Obviously that's not the
case at all, so let's get them in shape!
If you've been thinking "I should probably add this to the release
notes at some point", now is the time :-)
I have a list below of changes that might be worth mentioning. I
