           Summary: Significant slowdown when compiling computed-goto code
                    in Parrot
           Product: gcc
           Version: 3.4
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: c
        AssignedTo: unassigned at gcc dot gnu dot org
        ReportedBy: ahaas at airmail dot net
                CC: gcc-bugs at gcc dot gnu dot org
  GCC host triplet: i586-pc-linux-gnu

The GCC-3.4 development snapshots take 5x or 6x as long to compile the
computed-goto heavy 'core_ops_cg.c' in Parrot. GCC-3.3 compiles this file in
about five or six minutes on my slow machine - GCC-3.4 takes 30 or more minutes.
The memory usage appears to be roughly the same as that of GCC-3.3 as indicated
by top.

Parrot is the engine on what will be Perl 6. The 'core_ops_cg.c' file is
generated automatically by the Parrot build process and is about 280K in size.
Parrot can be downloaded from
