           Summary: operand to volatile asm incorrectly removed
           Product: gcc
           Version: 3.4
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: inline-asm
        AssignedTo: rth at gcc dot gnu dot org
        ReportedBy: rth at gcc dot gnu dot org
                CC: gcc-bugs at gcc dot gnu dot org
 GCC build triplet: i686-linux
  GCC host triplet: i686-linux
GCC target triplet: i686-linux

The first attached test case canaries the problem by generating an
obviously bogus "used before set" warning with -Wall.  An x86-specific
modification yields a test case that demonstrates the loss of an
input operand to a volatile inline asm.
