From 3d793962becf3a345cfff96202f3c6c27a1fb5d4 Mon Sep 17 00:00:00 2001 From: Johnny Chen Date: Thu, 24 Mar 2011 01:40:42 +0000 Subject: [PATCH] Load/Store Multiple: These instructions were changed to not embed the addressing mode within the MC instructions We also need to update the corresponding assert stmt. Also add two test cases. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@128191 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/Target/ARM/Disassembler/ARMDisassemblerCore.cpp | 8 ++++---- test/MC/Disassembler/ARM/arm-tests.txt | 6 ++++++ 2 files changed, 10 insertions(+), 4 deletions(-) diff --git a/lib/Target/ARM/Disassembler/ARMDisassemblerCore.cpp b/lib/Target/ARM/Disassembler/ARMDisassemblerCore.cpp index d92a019c13e..e000cab815b 100644 --- a/lib/Target/ARM/Disassembler/ARMDisassemblerCore.cpp +++ b/lib/Target/ARM/Disassembler/ARMDisassemblerCore.cpp @@ -1235,13 +1235,13 @@ static bool DisassembleStMiscFrm(MCInst &MI, unsigned Opcode, uint32_t insn, } // The algorithm for disassembly of LdStMulFrm is different from others because -// it explicitly populates the two predicate operands after operand 0 (the base) -// and operand 1 (the AM4 mode imm).
