            Bug ID: 15629
           Summary: no access to line table from python
           Product: gdb
           Version: HEAD
            Status: NEW
          Severity: enhancement
          Priority: P2
         Component: python
          Assignee: unassigned at sourceware dot org
          Reporter: tromey at redhat dot com

There is no way to access the line table from Python.
I'd like to have some access so I can determine which
lines in a given source file are executable.
Insight can do this, see gdbtk-cmds.c:gdb_loadfile

--- Comment #1 from Phil Muldoon <pmuldoon at redhat dot com> ---
For this API I was thinking of a simple dictionary returned from a symtab
object.

linetable = foo.linetable()

The dictionary key would be the source line number, and the value would be a
tuple containing all the $pc locations associated with that line number (a line
can have multiple $pc locations for things like the "for" c statement, or
compound commands).

What do you think?

The only concern is that the resulting table may be "too big".  That
is, it's worth looking at what happens if you take this approach with
a large source file -- say, pick the longest one in gdb and try it.
If that result isn't too bad then I think this approach is fine.
