Synopsis: [x86 SSE2] incorrect code generated
State-Changed-From-To: open->closed
State-Changed-By: hubicka
State-Changed-When: Sun Apr 6 13:11:33 2003
State-Changed-Why:
The testcase looks wrong to me - the addition uses uninitialized operand, GCC decides to initialize to 0 and thus eliminates it. This is valid transformation. I believe the pand also has correct order of operands.
