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.

◆ RegIdArrayPtr

using gem5::StaticInst::RegIdArrayPtr = RegId (StaticInst:: *)[]

Constructor & Destructor Documentation

◆ StaticInst()

gem5::StaticInst::StaticInst ( const char *  _mnemonic,
OpClass  op_class 
)
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()

pure virtual

◆ asBytes()

virtual size_t gem5::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 gem5::SparcISA::SparcStaticInst, gem5::RiscvISA::RiscvStaticInst, gem5::ArmISA::ArmStaticInst, and gem5::PowerISA::PowerStaticInst.

Definition at line 403 of file static_inst.hh.

◆ branchTarget() [1/2]

TheISA::PCState gem5::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).

Reimplemented in gem5::ArmISA::BranchImmImmReg64, gem5::ArmISA::BranchImmReg64, and gem5::ArmISA::BranchImm64.

Definition at line 61 of file static_inst.cc.

References panic.

Referenced by gem5::o3::DynInst::branchTarget(), and hasBranchTarget().

◆ branchTarget() [2/2]

TheISA::PCState gem5::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 gem5::PowerISA::BranchRegCondOp, gem5::PowerISA::BranchDispCondOp, and gem5::PowerISA::BranchOp.

◆ destRegIdx()

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

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

◆ disassemble()

const std::string & gem5::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 gem5::PowerISA::PCDependentDisassembly.
