Mikhail Fursov commented on HARMONY-3691:
-----------------------------------------

I checked the fix with 'build test' on Linux and Windows both.
EM64T plaftorm is not affected by the fix.

> While working on HARMONY-3652 I found that BTR pass handles DefScope_SemiTemporary incorrectly.
> Here is a test to reproduce:
> public class Test {
>     public static void main( String argv[] ) {
>         System.out.println(foo());
>     }
>     static int foo() {
>         int a  = 10;
>         boolean b = false;
>         if ( (a > 10 ? 20 : 30) == 30 ) {
>             b = true;
>         }
>         if (!b) {
>             return 40;
>         }
>         return 50;
>     }
> }
> RI and JET print '50' and -Xem:opt  prints '40' here.
> I'm going to fix this bug today.
