Auto variables display

Hello, All.

In MS Visual Studio debugger there is a very convenient feature - "Auto"
watch window tab, which displays the variables, referenced at the current
program statement. I.e. when you step across "i=j;" it displays i and j,
when you step across "x=f(a+b,*c)" displays a,b and c, etc.
This allows to see automatically just the values that affect current step
execution and see the error when and where it happens.

The question is: does GDB support something like this and also are
there the debug info formats that provide the mapping of the source lines
(or code addresses) to the set of variables, references at the point?

TIA,
Konstantin.
