26 Oct 2009 Those are the same instruction. The "l" suffix on cmpl is to indicate to the assembler the size of the arguments, where "l" indicates they are "long" (4-byte) words. Other variations you might see are "q", for quad (8-byte) words, "w" for regular (2-byte) words, etc. In the absence of a suffix, the assembler will infer
Review of x86 assembly. • Mostly two operand instructions But a lot of documentation uses Intel syntax. • Examples: Assembly cmpl – like subl, but discards subtraction result. • Stack instructions: Stack op equivalent pushl %eax subl $4,%esp movl %eax,(%esp) popl %eax movl (%esp),%eax addl $4,%esp. • Other stack
x64 Cheat Sheet. Fall 2017. 1. x64 Registers x64 assembly code uses sixteen 64-bit registers. Additionally, the lower bytes of some of these registers may be x86-64 Guide. Doeppner. 3.2 Arithmetic Operations. Unless otherwise specified, all arithmetic operation instructions have one suffix. 3.2.1 Unary Operations.
This section should not be considered an exhaustive list of x86 instructions, but rather a useful subset. . The idiv instruction divides the contents of the 64 bit integer EDX:EAX (constructed by viewing EDX as the most significant four bytes and EAX as the least significant four bytes) by the

x86 Instruction Set Reference. Derived from the September 2014 version of the Intel® 64 and IA-32 Architectures Software Developer's Manual, volumes 2A and 2B. More info at zneak/x86doc. This reference is not perfect. It's been mechanically separated into distinct files by a dumb script. It may be enough to replace the
8 Mar 2013 cmpl subtracts -0x10(%ebp) from $0x7 and modifies flags: AF CF OF PF SF ZF. if -0x10(%ebp) which is one of your function arguments, equals 0x7 then the flag ZF is set. jne 80484db means that if the two compared numbers are different (ZF=0), jump to 80484db. To summerize, your code is equivalent to :
read and understand (most) of the 64bit x86 assembly that gcc is likely to produce. • x86 is a poorly-designed ISA. It's a mess, but it is the most widely used ISA in the world today. • It breaks almost every rule of good ISA design. • Just because it is popular does not mean it's good. • Intel and AMD have managed to engineer (
If arg2 is an immediate value it will be sign extended to the length of arg1 . The EFLAGS register is set in the same manner as a sub instruction. Note that the GAS/AT&T syntax can be rather confusing, as for example cmp $0, %rax followed by jl branch will branch if %rax < 0 (and not
