Subject: [PATCH v3 25/25] powerpc/opcodes: Remove unused PPC_INST_XXX macros
Date: Mon,  9 May 2022 07:36:23 +0200	[thread overview]
Message-ID: <8c28636126f69141419953b5638b4a908c184dc1.1652074503.git.christophe.leroy@csgroup.eu> (raw)
In-Reply-To: <cover.1652074503.git.christophe.leroy@csgroup.eu>

The following PPC_INST_XXX macros are not used anymore
outside ppc-opcode.h:
	- PPC_INST_LD
	- PPC_INST_STD
	- PPC_INST_ADDIS
	- PPC_INST_ADD
	- PPC_INST_DIVD

Remove them.
