Subject: [PATCH 19/26] gdbserver: fix the declared type of register_status in regcache
Date: Tue, 28 Feb 2023 12:28:17 +0100 [thread overview]
Message-ID: <0c082e1edb5933f2ac5a7aac06197f8957099628.1677582745.git.tankut.baris.aktemur@intel.com> (raw)
In-Reply-To: <cover.1677582744.git.tankut.baris.aktemur@intel.com>
The register_status field of regcache is declared as `unsigned char *`.
This is incorrect, because `enum register_status` from
gdbsupport/common-regcache.h is based on signed char and
REG_UNAVAILABLE is defined as -1. Fix the declared type.
The get/set methods already use the correct type, but we update cast
operations in two places.
