From: Chris Lattner Date: Sat, 17 Dec 2005 07:04:29 +0000 (+0000) Subject: Use the shared AsmPrinter code for some basic stuff. No functionality X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=1dbed16fec1de205a7e69cc5c63798ec18e17f4c;p=oota-llvm.git Use the shared AsmPrinter code for some basic stuff. No functionality change except for fewer .section directives emitted git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@24764 91177308-0d34-0410-b5e6-96231b3b80d8 --- diff --git a/lib/Target/Sparc/SparcAsmPrinter.cpp b/lib/Target/Sparc/SparcAsmPrinter.cpp index a21f4993589..8473c1556fb 100644 --- a/lib/Target/Sparc/SparcAsmPrinter.cpp +++ b/lib/Target/Sparc/SparcAsmPrinter.cpp @@ -18,6 +18,7 @@ #include "llvm/DerivedTypes.h" #include "llvm/Module.h" #include "llvm/Assembly/Writer.h" +#include "llvm/CodeGen/AsmPrinter.h" #include "llvm/CodeGen/MachineFunctionPass.h" #include "llvm/CodeGen/MachineConstantPool.h" #include "llvm/CodeGen/MachineInstr.h" @@ -33,21 +34,8 @@ using namespace llvm; namespace { Statistic<> EmittedInsts("asm-printer", "Number of machine instrs printed"); - struct SparcV8AsmPrinter : public MachineFunctionPass { - /// Output stream on which we're printing assembly code. - /// - std::ostream &O; - - /// Target machine description which we query for reg. names, data - /// layout, etc. - /// - TargetMachine &TM; - - /// Name-mangler for global names. - /// - Mangler *Mang; - - SparcV8AsmPrinter(std::ostream &o, TargetMachine &tm) : O(o), TM(tm) { } + struct SparcV8AsmPrinter : public AsmPrinter { + SparcV8AsmPrinter(std::ostream &O, TargetMachine &TM) : AsmPrinter(O, TM) {} /// We name each basic block in a Function with a unique number, so /// that we can consistently refer to them later.
