From 5694c5fdb118773d746eb5fb2a4f4d76b65a9075 Mon Sep 17 00:00:00 2001 From: Daniel Sanders Date: Fri, 11 Sep 2015 14:34:41 +0000 Subject: [PATCH] [mips] Add missing MIPS-II disassembler tests. These tests were found by llvm-mc-fuzzer (see http://reviews.llvm.org/D12723) and were verified by checking the disassembler output is accepted by GAS. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@247414 91177308-0d34-0410-b5e6-96231b3b80d8 --- .../Disassembler/Mips/mips2/invalid-xfail.txt | 13 +++++++++++++ .../MC/Disassembler/Mips/mips2/valid-mips2.txt | 18 ++++++++++++++++++ .../MC/Disassembler/Mips/mips2/valid-xfail.txt | 13 +++++++++++++ 3 files changed, 44 insertions(+) create mode 100644 test/MC/Disassembler/Mips/mips2/invalid-xfail.txt create mode 100644 test/MC/Disassembler/Mips/mips2/valid-xfail.txt diff --git a/test/MC/Disassembler/Mips/mips2/invalid-xfail.txt b/test/MC/Disassembler/Mips/mips2/invalid-xfail.txt new file mode 100644 index 00000000000..b3fd1c49edc --- /dev/null +++ b/test/MC/Disassembler/Mips/mips2/invalid-xfail.txt @@ -0,0 +1,13 @@ +# RUN: llvm-mc %s -triple=mips-unknown-linux -disassemble -mcpu=mips2 | FileCheck %s +# XFAIL: * + +# Start with a valid instruction.
