Hi guys,
I have an odd one.
I am trying to swap the data between two locations like so;
mov ecx,[eax+4]
mov edx,[eax+16]
mov [eax+16],ecx
mov [eax+4],edx
But the data remains the same.
If I comment one of the last lines, I can verify that the data is being copied from one location to the other.
Is this some weird CPU cache quirk or something?
Can't be. Post full code.
Russ, nope nothing in between that's the actual flow of the code. And this is the only call to this location.
; The WIP proc
MatrixTranspose PROC matrix:DWORD
mov eax, matrix ; Store the address of 'matrix' in eax
mov edx,[eax+16] ; _21
mov ecx,[eax+4] ; _12
mov [eax+16],ecx
mov [eax+4],edx
ret
MatrixTranspose ENDP
;Initialising a 4x4 matrix like this.
testMat real4 11.0,12.0,13.0,14.0,21.0,22.0,23.0,24.0,31.0,32.0,33.0,34.0,41.0,42.0,43.0,44.0
;Calling the proc like this
invoke MatrixTranspose, addr testMat
Got me bewildered. :dazzled:

Have you tried looking at it in ollydbg, or other???
Not real familiar with it, but I will give it a go.
Hmmm. Trying to make sense of OllyDebug, but the code I am looking at looks nothing like what I have typed in. Not even remotely similar.
[edit]
I wrapped the code with a bunch of NOP's so I could find the bit in question.
Just trying to figure out how to read these registers.
Since newbies, no offense of course, usually commit newbie mistakes it is advisable that they post the whole code .

None taken :biggrin:
I'll take out the excess guff and see if I can post something minimal to replicate. :t
FWIW - OllyDebug showed this

Wolf,
What is in EAX to start with ?
LATER :
The code seems to work OK but I don't know what you are doing with it.

If eax is from a struct, try ESI instead of EAX ( don't forget to preserve ESI )
I just rewrote the program to be a console application and the proc works fine.
I think I'll back away slowly and chalk this up to a WTF. :eusa_snooty:
Russ,
Leave this stuff to the older guys. We keep the Campus for people learning assembler and the noise although well intended is a distraction.
Wolf,
Don't give up on what you were trying, that type of data swap is common in the guts of a sort and its useful code to understand.
Hey Hutch,
Nah, haven't given up. Just going to use a console 'test bed' instead of mucking around with a windows one. :t
All of this is in order to streamline my Matrix library I have created, just to give easy output to make sure the numbers are correct, so I am better with a small console program anyway.
I must have done something weird somewhere in my windows app, as it has been displaying the correct anticipated values all day long until this hiccup.
Certainly haven't given up. I have come so far in such a short time. :biggrin:

wtf? ::)
I am a bit dubious that 'ConverterDD.inc' is doing the right thing.
I had to add an extra phantom value of 0.0 at the end of my real4 array to make the value of '44.0' display correctly.
testMat real4 11.0,12.0,13.0,14.0,21.0,22.0,23.0,24.0,31.0,32.0,33.0,34.0,41.0,42.0,43.0,44.0 ,0.0
Otherwise invoke ConvertFloat4DF, addr testMat+60, addr szFloat just displays a garbage value.
Maybe the source of the problem in my other project??
This example doesn't work with eax, but it does with esi.
D3DMatrixTranspose proc pOut:DWORD,pM2:DWORD
mov esi,offset pM
movaps xmm0,[esi+0] ; [0 1 2 3]
movaps xmm1,[esi+16] ; [4 5 6 7]
movaps xmm4,[esi+32] ; [8 9 A B]
movaps xmm3,[esi+48] ; [C D E F]
This with parameters works well with eax.
D3DMatrixTranspose proc pOut:DWORD,pM:DWORD
; [0 1 2 3] [0 4 8 C]
; [4 5 6 7] [1 5 9 D]
; [8 9 A B] [2 6 A E]
; [C D E F] [3 7 B F]
mov eax,pM
movaps xmm0,[eax+0] ; [0 1 2 3]
movaps xmm1,[eax+16] ; [4 5 6 7]
movaps xmm4,[eax+32] ; [8 9 A B]
movaps xmm3,[eax+48] ; [C D E F]
At least it behaves like that on my machine.
EDIT: Aaaargh, I was totally wrong. :dazzled:
I used ESI only because I used windows functions as well.
Sorry for the misconception.
Think I need a break and clear my mind. :icon_mrgreen:

Hmmm. Trying to make sense of OllyDebug, but the code I am looking at looks nothing like what I have typed in. Not even remotely similar.
The usual approach is to insert an
int 3 just in front of the code you want to study. Then you launch the exe with Olly, hit F9 (=run!), and voilà, it stops right there and you can watch, hitting F7, what happens.
In the upper right corner, there is the "Registers" window. Right-click on EAX and choose "Follow in dump". Now, hitting F7, you can watch what exactly happens to [eax+4] and [eax+16]. Note that Olly uses hex notation, so
eax+10 means
eax+10h.
Again: If eax is the correct pointer, those few lines will swap the memory content. There are no hidden CPU quirks, you can trust intel and AMD 8)
mov ecx,[eax+4]
mov edx,[eax+16]
mov [eax+16],ecx
mov [eax+4],edxBtw, here is another method that does the swap with one single register:
push [eax+4]
push [eax+16]
pop [eax+4]
pop [eax+16]It takes 7 cycles instead of 4, so it is slower, but if you need the registers for other uses and your number of iterations is below ten Millions, that is not a problem.
something Jj forgot to say about Olly: you may want to set Olly to start at you program starting point, otherwise it will not
I tracked down where the fault is. Still doesn't make much sense to me though.
It is to do with the loop
myloop:
invoke MatrixTranspose, addr testMat
mov eax, ddCounter
inc eax
mov ddCounter, eax
cmp eax, ddCount
jl myloop
If I comment out the loop code the MatrixTranspose function works correctly.
I know that 'invoke' stores its result in EAX, but EAX is immediately overwritten on the next line.
So I am still a little confused as to why this should affect the MatrixTranspose prototype.
Even if I change EAX to ECX the fault remains.
[edit]
Arghhh.... Worked it out.
It is an absolute noob bug.
Because I am testing performance in a loop I am continuously transposing the same matrix. Just so happens because I am working with an even number of iterations, I am transposing the matrix back to what it was to begin with. ROFL.
Man, what a stupid mistake :P
:biggrin:
Something we all have is a list of stupid mistakes, the more you make, the faster you get at fixing them. Its called "programming". :P
Haha true!
I'm usually fast with debugging in C++ and the likes.
Bit slower debugging my ASM because, I guess, the confidence isn't quite there yet.
Ripping through things though. In the past two weeks I have written over 2000 lines of code in ASM. So in reality the code produced vs questions asked ratio is pretty good. :bgrin:

The problem seems to be this: you dont show what/how you are doing, only some things.
Other important things you dont show (
we try to guess).
This shows what you want. It needs the file
InputPrint.mac (.zip below)
and we need to include
InputPrintProc.inc (.zip below) to use some macros in InputPrint.mac.
You may use it to input/print matrixes...

Hi LoneWolff, The problem you post in the reply #14 was solved in my reply #21. You said that you added one dword (0.0) to the last value in TestMat and in this way ConvertFloat4DF shows the last value 44.0 correctly. Note that if we define szFloat after TestMat without one dword behind we need to add one dword (dd or real4) in the TestMat.This:Quote
TestMat real4 a,b,.......,z, 0.0
szFloat db 16 dup (?)
is the same as this:Quote
TestMat real4 a,b,.......,z
dd 0
szFloat db 16 dup (?)
Wherever we define szFloat we need to put a dword behind. ConvertFloat4DF only works correctly in this way. This is why i gave the answer "YES it seems". The first post of ConverterDD was in 19 April 2013 and i never used it. Now i am reading it again and i found out that the algorithm to examine any real4 when we call ConvertFloat4DF doesnt test the exponent part (in DL). It tests only for DL=FFh.
If DL=0 and fraction part (in EAX) is 0, the result may be 0 if the bit sign is 0 or -0 (replaced by 0) if the bit sign is 1. If DL=0 but EAX is not, the procedure will exit with an error (is a denormalized value). Now, if you know, you may correct it. So, as soon as possible, i will correct this bug and i will post it and i will show it here to you. Thanks :t
