Register information.
The sum of numFPDestRegs(), numIntDestRegs(), numVecDestRegs(), numVecElemDestRegs() and numVecPredDestRegs() equals numDestRegs(). The former two functions are used to track physical register usage for machines with separate int & FP reg files, the next three are for machines with vector and predicate register files.

Detailed Description

Base, ISA-independent static instruction class.

The main component of this class is the vector of flags and the associated methods for reading them. Any object that can rely solely on these flags can process instructions without being recompiled for multiple ISAs.

Constructor & Destructor Documentation

StaticInst()

StaticInst::StaticInst ( const char *  _mnemonic, ExtMachInst  _machInst, OpClass  __opClass  )

inlineprotected

Constructor.

It's important to initialize everything here to a sane default, since the decoder generally only overrides the fields that are meaningful for the particular instruction.

Member Function Documentation

advancePC()

virtual void StaticInst::advancePC ( TheISA::PCState &  pcState ) const

pure virtual

Referenced by GenericISA::M5DebugFault::advancePC(), SparcISA::advancePC(), X86ISA::advancePC(), RiscvISA::advancePC(), Minor::Decode::evaluate(), SESyscallFault::invoke(), and ArmISA::SupervisorCall::invoke().

asBytes()

virtual size_t StaticInst::asBytes ( void *  buf, size_t  max_size  )

inlinevirtual

Instruction classes can override this function to return a a representation of themselves as a blob of bytes, generally assumed to be that instructions ExtMachInst.

buf is a buffer to hold the bytes. max_size is the size allocated for that buffer by the caller. The return value is how much data was actually put into the buffer, zero if no data was put in the buffer, or the necessary size of the buffer if there wasn't enough space.

Reimplemented in SparcISA::SparcStaticInst, RiscvISA::RiscvStaticInst, ArmISA::ArmStaticInst, and PowerISA::PowerStaticInst.

Definition at line 375 of file static_inst.hh.

branchTarget() [1/2]

TheISA::PCState StaticInst::branchTarget ( const TheISA::PCState &  pc ) const

virtual

Return the target address for a PC-relative branch.

Invalid if not a PC-relative branch (i.e. isDirectCtrl() should be true).

Definition at line 105 of file static_inst.cc.

References panic.

Referenced by BaseDynInst< Impl >::branchTarget().

branchTarget() [2/2]

TheISA::PCState StaticInst::branchTarget ( ThreadContext *  tc ) const

virtual

Return the target address for an indirect branch (jump).

The register value is read from the supplied thread context, so the result is valid only if the thread context is about to execute the branch in question. Invalid if not an indirect branch (i.e. isIndirectCtrl() should be true).

Reimplemented in PowerISA::BranchRegCond.

Definition at line 113 of file static_inst.cc.

References panic.

Referenced by TimingSimpleCPU::completeDataAccess().

destRegIdx()

const RegId& StaticInst::destRegIdx ( int  i ) const

inline

Return logical index (architectural reg num) of i'th destination reg.

Only the entries from 0 through numDestRegs()-1 are valid.

disassemble()

const string & StaticInst::disassemble ( Addr  pc, const Loader::SymbolTable *  symtab = nullptr  ) const

virtual

Return string representation of disassembled instruction.

The default version of this function will call the internal virtual generateDisassembly() function to get the string, then cache it in cachedDisassembly. If the disassembly should not be cached, this function should be overridden directly.

Reimplemented in PowerISA::PCDependentDisassembly.
