Insufficient operands for mov
NettetThe "invalid instruction suffix" error message makes little sense, although note that Intel syntax doesn't use operand-size suffixes. (For some reason movb [0], 'A' is accepted, though.) Instead use square brackets to avoid ambiguity; recommended for any memory operand, even if the address is a symbol instead of a literal number.

Case 1 : You are moving the value at address specified by register rsp to the register eax. Therefore, you should use movl which means move a long value. This is done because the eax register is 4 bytes wide which make up a long. The same applies to the other cases. …
NettetThe MOVinstruction cannot move from memory to memory or from segment register to segment register are not allowed. Memory-to-memory moves can be performed, however, by the string move instruction MOVS. XCHG(Exchange) swaps the contents of two operands. the place of three MOVinstructions.

This is wrong, too as both operands to mov must have the same size. You can fix this by making c0 an unsigned char and changing mov %%ax, %0 to mov %%ah, %0. Anyway, using a mov in inline assembly is usually wrong but here it's hard to avoid as you can't easily tell gcc to expect c0 in the ah register. Share.
