Subject: [PATCH V2 1/2] gdb/arm: Rename arm_cache_is_sp_register to
Date: Thu, 7 Jul 2022 11:19:59 +0200 [thread overview]
Message-ID: <20220707091959.GC5239@gnbcxd0114.gnb.st.com> (raw)
In-Reply-To: <20220707091722.GB5239@gnbcxd0114.gnb.st.com>
All usage of this helper are really made to check if the register is
one of the alternative SP (MSP/MSP_S/MSP_NS/PSP/PSP_S/PSP_NS) with
ARM_SP_REGNUM case being handled separately.
