Insufficient operands for mov

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. NettetOperands Three kinds of operands are generally available to the instructions: register, memory, and immediate. Indirect operands are available onlyto jump and call instructions. The assembler always assumes it is generating code for a 32-bit segment.

NettetBased and indexed operands may both be used with displacements. Displacements may be either offsets(of memory variables) or constants. Examples: mov ax, [bx] ; based operand mov dx, [bx+10] ; based operand with constant displacement mov cx, array[bx] ; based operand with an offset displacement NettetLogical AND between all bits of two operands. Result is stored in operand1. These rules apply: 1 AND 1 = 1 1 AND 0 = 0 0 AND 1 = 0 0 AND 0 = 0 Example: MOV AL, 'a' ; AL = 01100001b AND AL, 11011111b ; AL = 01000001b ('A') RET CALL procedure name label 4-byte address Transfers control to procedure. forks county jail roster https://merklandhouse.com
