From 5166ed9c9c6f60859295d932b65c5c5a19984dfd Mon Sep 17 00:00:00 2001 From: Jan Vrany Date: Tue, 4 Feb 2025 13:56:49 +0000 Subject: gdb/python: add subblocks property to gdb.Block This commit adds new propery "subblocks" to gdb.Block objects. This allows Python to traverse block tree starting with global block.
