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.

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()

Expected< bool > AMDGPUDisassembler::onSymbolStart ( SymbolInfoTy & Symbol, uint64_t & Size, ArrayRef< uint8_t > Bytes, uint64_t Address ) 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.
