From ca97e3568e32ca58c4bc59b4cfb5a53592ad3a2e Mon Sep 17 00:00:00 2001 From: Nathan Rossi Date: Mon, 14 Nov 2022 08:17:18 +0000 Subject: [PATCH] oeqa/selftest/minidebuginfo: Create selftest for minidebuginfo Add a new selftest to validate minidebuginfo support. This selftest builds a complete target image with PACKAGE_MINIDEBUGINFO enabled. ELFs included in the image are expected to have minidebuginfo included in the resulting executables and shared libraries, the self test validates this by unpacking the image and checking for the associated ".gnu_debugdata" section on busybox and libc ELFs.
