DecodeStatus AMDGPUDisassembler::getInstruction ( MCInst &  Instr, uint64_t &  Size, ArrayRef< uint8_t >  Bytes, uint64_t  Address, raw_ostream &  CStream  ) const

overridevirtual

Returns the disassembly of a single instruction.

Parameters

Instr	- An MCInst to populate with the contents of the instruction.
Size	- A value to populate with the size of the instruction, or the number of bytes consumed while attempting to decode an invalid instruction.
Address	- The address, in the memory space of region, of the first byte of the instruction.
Bytes	- A reference to the actual bytes of the instruction.
CStream	- The stream to print comments and annotations on.

Returns

- MCDisassembler::Success if the instruction is valid, MCDisassembler::SoftFail if the instruction was disassemblable but invalid, MCDisassembler::Fail if the instruction was invalid.

Implements llvm::MCDisassembler.

onSymbolStart()

std::optional< MCDisassembler::DecodeStatus > AMDGPUDisassembler::onSymbolStart ( SymbolInfoTy &  Symbol, uint64_t &  Size, ArrayRef< uint8_t >  Bytes, uint64_t  Address, raw_ostream &  CStream  ) const

overridevirtual

Used to perform separate target specific disassembly for a particular symbol.

May parse any prelude that precedes instructions after the start of a symbol, or the entire symbol. This is used for example by WebAssembly to decode preludes.

Base implementation returns std::nullopt. So all targets by default ignore to treat symbols separately.

Parameters

Symbol	- The symbol.
Size	- The number of bytes consumed.
Address	- The address, in the memory space of region, of the first byte of the symbol.
Bytes	- A reference to the actual bytes at the symbol location.
CStream	- The stream to print comments and annotations on.

Returns

- MCDisassembler::Success if bytes are decoded successfully. Size must hold the number of bytes that were decoded.

• MCDisassembler::Fail if the bytes are invalid. Size must hold the number of bytes that were decoded before failing. The target must print nothing. This can be done by buffering the output if needed.
• std::nullopt if the target doesn't want to handle the symbol separately. Value of Size is ignored in this case.
