For the purposes of my compiler, I was compiling the nonsense
function at the bottom

I noticed that the bytecodes produced included the following:

  90 iconst_0
  91 goto 94
  94 ifne 31

and that there are no other references to "byte 94". So these three
instructions do absolutely nothing

Needless to say, the Sparc code faithfully reproduces the compiled code.

Block #6
    001. 30800000 ba,a ... //branch #7#
Block #7
    001. 80a00000 sub.cc %0, %0 => %0
    002. 12800000 bne ... //branch #2#
    003. 01000000 nop

int a = 10; int b = 20; int c = 30; int d = 40; int e = 50;
baz(a, b, c, d, e);
for (int i = 0; baz(b, c, d, e, a), i < 10; i = Math.abs(i)) {
baz(c, d, e, a, b);
if (i == 3) {
baz(d, e, a, b, c);
break;
}
baz(e, a, b, c, d);
}
baz(c, d, e, a, b);
return 10;
    }

    public static void baz(int a, int b, int c, int d, int e) { }
