From: Alexander Fedotov Date: Sat, 30 Sep 2017 09:31:37 +0000 (+0300) Subject: Add new mnemonics for VLE multiple load instructions X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=d2e6c9a3682f0ac811ac1676d221c55162938b61;p=binutils-gdb.git Add new mnemonics for VLE multiple load instructions opcodes/ * ppc-opc.c (vle_opcodes): Add e_lmvsprw, e_lmvgprw, e_lmvsrrw, e_lmvcsrrw and e_lmvcsrrw as official mnemonics for VLE multimple load/store instructions. Old e_ldm* variants are kept as aliases.
