Access to symbol table data maintained by GDB on the inferior
is exposed to Python via two objects: gdb.Symtab_and_line and
gdb.Symtab. Symbol table and line data for a frame is returned
from the find_sal method in gdb.Frame object.
See Frames In Python.
For more information on GDB’s symbol table management, see Examining the Symbol Table, for more information.
A gdb.Symtab_and_line object has the following attributes:
The symbol table object (gdb.Symtab) for this frame.
This attribute is not writable.
Indicates the start of the address range occupied by code for the current source line. This attribute is not writable.
Indicates the end of the address range occupied by code for the current source line. This attribute is not writable.
Indicates the current line number for this object. This attribute is not writable.
A gdb.Symtab_and_line object has the following methods:
Returns True if the gdb.Symtab_and_line object is valid,
False if not. A gdb.Symtab_and_line object can become
invalid if the Symbol table and line object it refers to does not
exist in GDB any longer. All other
gdb.Symtab_and_line methods will throw an exception if it is
invalid at the time the method is called.
A gdb.Symtab object has the following attributes:
The symbol table’s source filename. This attribute is not writable.
The symbol table’s backing object file. See Objfiles In Python. This attribute is not writable.
The name and possibly version number of the program that
compiled the code in the symbol table.
The contents of this string is up to the compiler.
If no producer information is available then None is returned.
This attribute is not writable.
A gdb.Symtab object has the following methods:
Returns True if the gdb.Symtab object is valid,
False if not. A gdb.Symtab object can become invalid if
the symbol table it refers to does not exist in GDB any
longer. All other gdb.Symtab methods will throw an exception
if it is invalid at the time the method is called.
Return the symbol table’s source absolute file name.
Return the global block of the underlying symbol table. See Blocks In Python.
Return the static block of the underlying symbol table. See Blocks In Python.
Return the line table associated with the symbol table. See Line Tables In Python.
