Synopsis: gcc-3.0 (release): array subscripting error (-1) in loop_p() in alias.c

State-Changed-From-To: open->closed
State-Changed-By: rth
State-Changed-When: Tue Apr  2 03:00:24 2002
State-Changed-Why:
    Actually, the condition described can never happen legitimately;
    Index -1 is ENTRY_BLOCK, which would indicate that there is
    an edge from entry to exit that flows through no block, which
    is illegal.  So the bug is whereever created such a CFG.
    
    That said, all this has been completely rewritten for gcc 3.1.
