<div>
<pre>Given the following reproducer:
short s() {
return 32768.0;
}
char c() {
return 128.0;
}
We get the warnings:
warning: implicit conversion from 'double' to 'short' changes value from 32768
to 32767
and
warning: implicit conversion from 'double' to 'char' changes value from 128 to
127
HOWEVER, the LLVM-IR emitted actually replaces the 'ret' with ret i16 undef and
ret i8 undef respectively.
We should make this consistent, either by altering the commit message or by
changing the behavior.</pre>
