Attachement for bugreport #9085

(I pressed 'submit', forgot to set Submitter-Id, and then
 it reset my attachement without me noticing it...)

To be sure, here's the code attached:

/**
 * Compile with -c -Os -mregparm=2 -fschedule-insns -march=k6
 */

class Test
{
   unsigned char track;   // 0..79
   unsigned char head;    // 0..1
   unsigned char sector;  // 1..18

   int e1, e2;

public:
   void f( unsigned p1, unsigned p2, unsigned p3 );
};

void
Test::f( unsigned p1, unsigned p2, unsigned lb )
{
   e1 = p1;
   e2 = p2;    // without this one it will work

   // convert logical block to physical, this actually depends on drive parameters
   sector = lb%18 + 1;    // 1..18
   head   = (lb/18)&1;    // 0..1
   track  = lb/36;        // 0..79
}
>How-To-Repeat:
see #9085
