The general purpose register can contain the operand for any opcode. This provides true general purpose register use. However, there are restrictions. For example, there may be dedicated register for floating point and stack operations. In some cases, general purpose register can be used for addressing functions (e.g register indirect, displacement).

Nov 15, 2008 The first of them has a register as the first operand and a register or a Many disassemblers and debuggers (including OllyDbg) cannot

Rd is the destination register. Rn is the register holding the first operand. Operand2 is a flexible second operand. imm12 is any value in the range 0-4095.

2002-11-04 true. An indirect operand such as [eax + edi] can be passed to the INVOKE directive. true. The assembler checks the pointer type used with the ADDR operator against the pointer type declared in the PROC directive. For example, it prevents a pointer to DWORD from being passed to a … 4.3 Operating on Different Sized Operands Occasionally you may need to compute some value on a pair of operands that are not the same size. For example, you may need to add a word and a double word together or subtract a byte value from a word value.

A2150 word register cannot be first operand. A word register was specified to an instruction that cannot take it as the first operand. A2151 special register cannot be first operand. A special register was specified to an instruction that cannot take it as the first operand. A2152 coprocessor register cannot be first operand. A coprocessor

o The third version multiplies a 32-bit operand by the EAX register. The multiplier and multiplicand must always be the same size, and the product is twice their size. The first word of the instruction specifies the operation code and mode, and the second word specifies the address part. PC has the value 200 for fetching this instruction.

The product is then stored in the destination operand location. The IP register points to the memory offset of the next instruction in the code segment (it points to the first byte of the instruction). The IP register cannot be accessed by the programmer directly. The x86 registers can be used by using the MOV instructions.

error A2152: coprocessor register cannot be first operand; error A2070: invalid instruction operands; However, it is clearly possible to accomplish this simple task in x64. For example, the following is a functioning x64 program that I can assemble and run in GAS :

The other directive is "define word" or "dw" with the. same syntax as "db" but reserving a whole word of 16 bits instead of a byte. There are directives to declare a double or a quad word as well but we will. The first operand is a 16-bit word register or memory variable that contains the value of a selector. The second operand is a word register. If the RPL field of the second operand is greater than the RPL field of the first operand, ZF is set to 1 and the RPL field of the first operand is increased to match the RPL field of the second operand.
