            Bug ID: 65366
           Summary: gdbhooks.py is incompatible with Python3
           Product: gcc
           Version: 5.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: other
          Assignee: unassigned at gcc dot gnu.org
          Reporter: jan.kratochvil at redhat dot com
              Host: x86_64-linux-gnu

GDB Python support upstream has always been compatible with Python3.
Fedora since F-22 builds GDB with Python3 by default (<=F-21 GDB used Python2).

gdbhooks.py in GCC trunk is compatible with Python2 but not Python3.

gdb-7.9-10.fc23.x86_64
(gdb) source /home/jkratoch/redhat/gcchead/gcc/c/../gdbhooks.py
  File "/home/jkratoch/redhat/gcchead/gcc/c/../gdbhooks.py", line 372
    print format_[i]
                ^
SyntaxError: Missing parentheses in call to 'print'

Additionally after fixing the 'print' incompatibility one gets randomly:

dependence_info = {clique = 257, Python Exception <class 'NameError'> name
'long' is not defined:
base = 1}}}, type = }, 

I have a patch, going to post it.

Re-open.  Broke python 2 support.
