This is a fork from pymsasid. pymsasid is a x86 disassembler completely written in python. It supports disassembling in two syntax - Intel and AT&T. This fork adds one more syntax - C like syntax(eg add rax, 0x1 would be represented as rax += 0x1.
Disassemblers disassemble machine code into human readable assembly code. Although assembly mnemonics are human readable they are not as easy as reading an C code. Adding C like disassembly might help to read through assembly code quickly without the help of architecture assembly manual. However the purpose of assembly mnemonics cant be ignored, so this syntax just adds the C like disassembly as supplement to AT&T syntax.
##Example
push ebp # ebp => stack
mov rbp, rsp # rbp = rsp
push ebx # ebx => stack
sub rsp, 0x8 # rsp -= 0x8
cmp byte [rip+0x200be8], 0x0 # eflags._f = 0x0 - *((uint8_t)(rip+0x200be8))
jnz 0x4dL # if (!eflags.zf) goto 0x4dL
mov rbx, 0x600e40 # rbx = 0x600e40
mov rax, [rip+0x200be2] # rax = *((rip+0x200be2))
sub rbx, 0x600e38 # rbx -= 0x600e38
sar rbx, 0x3 # rbx ->>= 0x3;
sub rbx, 0x1 # rbx -= 0x1
cmp rax, rbx # eflags._f = rbx - rax
jae 0x26L # if (!eflags.cf) goto 0x26L
add rax, 0x1 # rax += 0x1
mov [rip+0x200bbd], rax # *((rip+0x200bbd)) = rax
call qword [rax8+0x600e38] # call *((uint64_t)(rax8+0x600e38))
mov rax, [rip+0x200baf] # rax = *((rip+0x200baf))
cmp rax, rbx # eflags._f = rbx - rax
jb -0x1cL # if (eflags.cf) goto -0x1cL
mov byte [rip+0x200b9b], 0x1 # *((uint8_t)(rip+0x200b9b)) = 0x1
add rsp, 0x8 # rsp += 0x8
pop ebx # ebx <= stack
pop ebp # ebp <= stack
ret # return
