[jakub@gcc.gnu.org]

Synopsis: gcc-3.1 prerelease with -O3 generates invalid i386 code.

State-Changed-From-To: open->analyzed
State-Changed-By: jakub
State-Changed-When: Sun May 12 23:26:26 2002
State-Changed-Why:
    This is because xmame is buggy. It wants an 8-bit register,
    but uses a "g" constraint. It has to use "qm" instead.
