From 59ee62d2418df8db499eca1ae17f5900dc2dcbba Mon Sep 17 00:00:00 2001 From: Evan Cheng Date: Mon, 11 Jul 2011 03:57:24 +0000 Subject: - Eliminate MCCodeEmitter's dependency on TargetMachine. It now uses MCInstrInfo and MCSubtargetInfo. - Added methods to update subtarget features (used when targets automatically detect subtarget features or switch modes). - Teach X86Subtarget to update MCSubtargetInfo features bits since the MCSubtargetInfo layer can be shared with other modules. - These fixes .code 16 / .code 32 support since mode switch is updated in MCSubtargetInfo so MC code emitter can do the right thing. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@134884 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/Target/SystemZ/SystemZInstrInfo.cpp | 12 ++++++++++++ lib/Target/SystemZ/SystemZSubtarget.cpp | 2 +- 2 files changed, 13 insertions(+), 1 deletion(-) (limited to 'lib/Target/SystemZ') diff --git a/lib/Target/SystemZ/SystemZInstrInfo.cpp b/lib/Target/SystemZ/SystemZInstrInfo.cpp index fae9a6a..ae41d68 100644 --- a/lib/Target/SystemZ/SystemZInstrInfo.cpp +++ b/lib/Target/SystemZ/SystemZInstrInfo.cpp @@ -21,6 +21,7 @@ #include "llvm/CodeGen/MachineInstrBuilder.h" #include "llvm/CodeGen/MachineRegisterInfo.h" #include "llvm/CodeGen/PseudoSourceValue.h" +#include "llvm/Target/TargetRegistry.h" #include "llvm/Support/ErrorHandling.h" #define GET_INSTRINFO_CTOR @@ -437,3 +438,14 @@ SystemZInstrInfo::getLongDispOpc(unsigned Opc) const { case SystemZ::MOV64Prm: return get(SystemZ::MOV64Prmy); } } + +MCInstrInfo *createSystemZMCInstrInfo() { + MCInstrInfo *X = new MCInstrInfo(); + InitSystemZMCInstrInfo(X); + return X; +} + +extern "C" void LLVMInitializeSystemZMCInstrInfo() { + TargetRegistry::RegisterMCInstrInfo(TheSystemZTarget, + createSystemZMCInstrInfo); +} diff --git a/lib/Target/SystemZ/SystemZSubtarget.cpp b/lib/Target/SystemZ/SystemZSubtarget.cpp index f6707f9..fe3046b 100644 --- a/lib/Target/SystemZ/SystemZSubtarget.cpp +++ b/lib/Target/SystemZ/SystemZSubtarget.cpp @@ -58,7 +58,7 @@ bool SystemZSubtarget::GVRequiresExtraLoad(const GlobalValue* GV, MCSubtargetInfo *createSystemZMCSubtargetInfo(StringRef TT, StringRef CPU, StringRef FS) { MCSubtargetInfo *X = new MCSubtargetInfo(); - InitSystemZMCSubtargetInfo(X, CPU, FS); + InitSystemZMCSubtargetInfo(X, TT, CPU, FS); return X; } -- cgit v1.1
