From d6c98ae63824854ea2175b362a10985cac7cfb32 Mon Sep 17 00:00:00 2001 From: Jyotsna Verma Date: Wed, 20 Feb 2013 16:13:27 +0000 Subject: Hexagon: Move HexagonMCInst.h to MCTargetDesc/HexagonMCInst.h. Add HexagonMCInst class which adds various Hexagon VLIW annotations. In addition, this class also includes some APIs related to the constant extenders. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@175634 91177308-0d34-0410-b5e6-96231b3b80d8 --- .../Hexagon/InstPrinter/HexagonInstPrinter.cpp | 44 ++++++++++++++-------- .../Hexagon/InstPrinter/HexagonInstPrinter.h | 17 +++++++-- lib/Target/Hexagon/InstPrinter/LLVMBuild.txt | 2 +- 3 files changed, 43 insertions(+), 20 deletions(-) (limited to 'lib/Target/Hexagon/InstPrinter') diff --git a/lib/Target/Hexagon/InstPrinter/HexagonInstPrinter.cpp b/lib/Target/Hexagon/InstPrinter/HexagonInstPrinter.cpp index c700354bda..36da6dfcc3 100644 --- a/lib/Target/Hexagon/InstPrinter/HexagonInstPrinter.cpp +++ b/lib/Target/Hexagon/InstPrinter/HexagonInstPrinter.cpp @@ -12,14 +12,14 @@ //===----------------------------------------------------------------------===// #define DEBUG_TYPE "asm-printer" -#include "HexagonInstPrinter.h" -#include "Hexagon.h" #include "HexagonAsmPrinter.h" -#include "HexagonMCInst.h" +#include "Hexagon.h" +#include "HexagonInstPrinter.h" +#include "MCTargetDesc/HexagonMCInst.h" +#include "llvm/MC/MCInst.h" #include "llvm/ADT/StringExtras.h" #include "llvm/MC/MCAsmInfo.h" #include "llvm/MC/MCExpr.h" -#include "llvm/MC/MCInst.h" #include "llvm/Support/raw_ostream.h" #include @@ -28,6 +28,8 @@ using namespace llvm; #define GET_INSTRUCTION_NAME #include "HexagonGenAsmWriter.inc" +const char HexagonInstPrinter::PacketPadding = '\t'; + StringRef HexagonInstPrinter::getOpcodeName(unsigned Opcode) const { return MII.getName(Opcode); } @@ -43,43 +45,42 @@ void HexagonInstPrinter::printInst(const MCInst *MI, raw_ostream &O, void HexagonInstPrinter::printInst(const HexagonMCInst *MI, raw_ostream &O, StringRef Annot) { - const char packetPadding[] = " "; const char startPacket = '{', endPacket = '}'; // TODO: add outer HW loop when it's supported too. if (MI->getOpcode() == Hexagon::ENDLOOP0) { // Ending a harware loop is different from ending an regular packet. - assert(MI->isEndPacket() && "Loop end must also end the packet"); + assert(MI->isPacketEnd() && "Loop-end must also end the packet"); - if (MI->isStartPacket()) { + if (MI->isPacketStart()) { // There must be a packet to end a loop. // FIXME: when shuffling is always run, this shouldn't be needed.
