[PATCH v2 0/1] gdb: add 'set print shadowed' to hide shadowed variables

[Stephan Rohr <stephan.rohr@intel.com>]

From: "Rohr, Stephan" <stephan.rohr@intel.com>

Hello all,

this is version 2 of the patch adding a new print option "set print
shadowed on|off".  You can find v1 of the patch at:

https://sourceware.org/pipermail/gdb-patches/2026-August/229335.html

Simon posted feedback:

https://sourceware.org/pipermail/gdb-patches/2026-August/229420.html

I addressed the feedback from v1 and implemented the following:

  * Added an option '-shadowed on|off' to the 'info locals' command.
  * Rephrased the "use 'set print shadowed on|off' .." message.
  * Fixed the corner case identified by Simon:

      Breakpoint 1, main () at test.c:3
      3           { int x = 2; x = x + 1; /* bp */ return x; }
      (gdb) set print shadowed off
      (gdb) info locals -t double
      No matching locals.
      Some shadowed variables were omitted, use 'set print shadowed on'
      to include them.

  * Avoid printing the "use 'set print shadowed' .." hint for every
    frame in the backtrace command.

I appreciate your feedback.

Thanks
Stephan
