From 44aeb523c85f1433966f6355fff28f0c481ba363 Mon Sep 17 00:00:00 2001 From: Nathan Rossi Date: Thu, 3 Nov 2022 07:56:06 +0000 Subject: 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.
