Subject: [PATCH 2/2] 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.
