From de40303b54bc458d7df0d4b4ee1d296df7fe98c7 Mon Sep 17 00:00:00 2001 From: Christophe Leroy Date: Thu, 7 Jul 2022 16:55:16 +0200 Subject: [PATCH] powerpc/ppc-opcode: Define and use PPC_RAW_SETB() We have PPC_INST_SETB then build the 'setb' instruction in the user. Instead, define PPC_RAW_SETB() and use it.
