Subject: [PATCH v2 6/7] target/ppc: Reorder PPC2 flags
Date: Thu, 20 Aug 2026 19:57:03 +0530	[thread overview]
Message-ID: <20260820142717.337686-7-rathc@linux.ibm.com> (raw)
In-Reply-To: <20260820142717.337686-1-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.
