From 17f6c83fb5ebf7db4fcc94a5be4c22d5a7bfe428 Mon Sep 17 00:00:00 2001 From: Jiong Wang Date: Mon, 3 Dec 2018 17:27:54 -0500 Subject: mips: bpf: fix encoding bug for mm_srlv32_op For micro-mips, srlv inside POOL32A encoding space should use 0x50 sub-opcode, NOT 0x90. Some early version ISA doc describes the encoding as 0x90 for both srlv and srav, this looks to me was a typo. I checked Binutils libopcode implementation which is using 0x50 for srlv and 0x90 for srav. v1->v2: - Keep mm_srlv32_op sorted by value.
