<0> call eax
<1> or maybe /usr/include/asm/unistd.h
<1> and that's it. that's the way all syscalls are called [except pipe and mmap, which are ****ed up exceptions]
<0> :D
<0> mwk: thanks in advance
<0> btw can i do
<0> mov eax, 0x01
<0> mov eax, 1 works too
<1> umm
<1> wait a moment
<1> whose *** was this 'call eax' thingie pulled from?
<2> hah :)
<0> what?
<1> whose *** was this 'call eax' thingie pulled from?
<2> ask smg ;)
<0> mwk: i dont know
<0> is call eax wrong?
<1> sure it is
<0> why?
<0> how i call then the syscall
<1> int 0x80
<0> what does int mean?
<1> call eax calls procedure at address eax
<3> system call
<1> which will be disastrous.
<1> no, it's not system call.
<1> it's INTerrupt
<3> int 0x80?
<1> you don't want to know what it means.
<1> int, in generic, isn't syscall
<3> sorry, linux specific was my thoguhts
<1> int 0x80 is one way of linux syscall
<1> well, it was also 0x80-specific.
<0> so what do i do in genereal?
<0> i mov eax, [syscall_value]
<0> mov ebx, [arg]
<1> you write 'int 0x80' and forget wat that means.
<0> int 0x80
<0> is this right?
<4> what is the difference between a preincrement and a postimcrement?
<0> mh
<0> if you speak english and latin you can get it :)
<1> JabberWalkie: m68k?
<4> mwk: yeah
<1> where the **** did you see preincrement in m68k?
<5> mwk so angry :)
<4> errr under addressing modes...
<1> you reading M68000PRM.pdf or something else?
<1> there is only one mention of preincrement here, and it seems to be an error
<4> no the HSC12 core users guide
<1> um, what is HSC12?
<1> cause, y'know, HSC12 isn't m68k
<4> well its for the 68HSC12 ISA
<4> errr 68HC12
<1> grml. so why the 'yeah' to 'm68k?'
<4> you ment the motorolla 6800 series yes?
<1> m68k is motorola 68000 processor and compatibles
<1> quite different from 68hc12 and other motorola microcontrollers
<4> ok
<0> sorry
<0> my server is borked
<0> i come back to talk soon
<1> yawn
<1> anyway
<1> since noone seems to help you...
<1> pre-increment is something like LDAA 5, +X
<1> this loads a byte from address X to accumulator A and increments X by 5
<1> post-increment is something like LDAA 5, X+
<1> this icrements X by 5 and loads a byte from newly-incremented address X to accumulator A
<1> errr.... ****
<1> strike that. reverse that.
<1> LDAA 5, +X is pre-increment
<1> it increments X by 5, then it takes value from newly-incremented address X and stuffs that to acumulator
<1> LDAA 5, X+ is post-increment
<1> and it first loads the value from address X, then it adds 5 to X
<1> pre-increment is increment-first, and use already-incremented value
<1> post-increment is use old value, then increment
