f8f6f4 instructions have different pseudos depending on the used formats.

In the disassembler table, we only have the variants with the largest register classes which assume using an fp8/bf8 format for both operands. The actual register class depends on the format in blgp and cbsz operands. Adjust the register classes depending on the used format.

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.

Expected< bool > AMDGPUDisassembler::onSymbolStart ( SymbolInfoTy Symbol,

) 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 false. So all targets by default decline 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.
Returns
- True if this symbol triggered some target specific disassembly for this symbol. Size must be set with the number of bytes consumed.
  • Error if this symbol triggered some target specific disassembly for this symbol, but an error was found with it. Size must be set with the number of bytes consumed.
  • False if the target doesn't want to handle the symbol separately. The value of Size is ignored in this case, and Err must not be set.
