Subject: [PATCH 6/7] target/ppc: Reorder PPC2 flags
Date: Wed, 15 Jul 2026 18:26:33 +0530 [thread overview]
Message-ID: <20260715125634.2107320-7-rathc@linux.ibm.com> (raw)
In-Reply-To: <20260715125634.2107320-1-rathc@linux.ibm.com>
Consolidation of different variations of Power ISA 2.07 flags
into the PPC2_ISA207 flag has left gaps in the flag encoding.
This patch reorders them, restoring the expected incremental order
without any gaps, freeing up bits for future use.
