From 47d6e4d0091ef425b1bb72627b140b0b7c186738 Mon Sep 17 00:00:00 2001 From: Colin LeMahieu Date: Wed, 4 Feb 2015 17:52:06 +0000 Subject: [PATCH] [Hexagon] Adding encoding information for absolute-reg mode stores. Xfailing a test until constant extenders are correctly put in the same packet. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@228158 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/Target/Hexagon/HexagonInstrInfo.cpp | 12 +- lib/Target/Hexagon/HexagonInstrInfoV4.td | 208 ++++++++++++++--------- test/CodeGen/Hexagon/always-ext.ll | 3 +- 3 files changed, 140 insertions(+), 83 deletions(-) diff --git a/lib/Target/Hexagon/HexagonInstrInfo.cpp b/lib/Target/Hexagon/HexagonInstrInfo.cpp index d61b9353b9c..f8de14ced0a 100644 --- a/lib/Target/Hexagon/HexagonInstrInfo.cpp +++ b/lib/Target/Hexagon/HexagonInstrInfo.cpp @@ -1533,14 +1533,14 @@ int HexagonInstrInfo::GetDotNewOp(const MachineInstr* MI) const { switch (MI->getOpcode()) { default: llvm_unreachable("Unknown .new type");
