; bin/opt -passes=inline reduced.ll -S
target datalayout = "e-m:e-p270:32:32-p271:32:32-p272:64:64-i64:64-i128:128-f80:128-n8:16:32:64-S128"
target triple = "x86_64-unknown-linux-gnu"
define i64 @caller(ptr %p1, ptr %p2) {
%1 = call i64 %p1(ptr %p2)
%2 = call i64 @callee(i64 %1)
ret i64 %2
}
define i64 @callee(i64 range(i64 0, 7) %0) {
%i = tail call i64 @llvm.umin.i64(i64 %0, i64 %0)
ret i64 %i
}
```
```
Attribute after last parameter!
%1 = call i64 %p1(ptr range(i64 0, 7) %p2)
