From 30fcf51e11c167ce6e7efab0706e958017657109 Mon Sep 17 00:00:00 2001 From: Max Filippov Date: Sun, 7 Jun 2015 22:43:49 +0300 Subject: [PATCH] xtensa: make sure ar_base is initialized ar_base is uninitialized for cores w/o windowed registers as their regmap doesn't have register 0x0100. Check that ar_base is initialized and if not initialize it with a0_base. gdb/ * xtensa-tdep.c (xtensa_derive_tdep): Make sure ar_base is initialized.
