The M$ compiler and gcc is very different. If you compare the assembler
code which is compiled from the same source, you can found the same
functions bodies, but inside the functions there are many differences.
Some time ago, I've ported a simple driver for an eprom programer from
M$ tools to the ReactOS build system. At the start it hasn't worked,
because I forgot the stdcall attributes for some functions. The
reassembled code was very different.
Their are not that big difference agre that scsiport is in c code
when you compile it you get machine code right when you compare the "C CODE from
scsiport.sys from
REACTOS" with microsoft asm from ida pro it will list the functions used and the
params used and
what cases it used around in the code what internal function their are called not so hard
BUT if
you compare GNU Asm Vs. Ms Asm their will be a big diff.
5. Microsoft Source leak my friend just downloaded it i
got parts of the
code what could be on my
1,33 mb floppy
If you was interessted to compare the ros and M$ code,
you have neverworked with a floppy. It is too simple to burn a cd or dvd.
If i want to use a floppy
i use a fucking floppy the parts i wanted to find out where small sections from shell32
and
scsiport.sys just to get some invidence from winnt4.0 and i got those thing one my so
simple
floppy i could use a dvd a cdrom a harddisk but why i could be on my floppy
6. Saw scsiport.sys where 90% identical i layout and
code and alittel of
shell32
Some parts of scsiport are from me. I've never seen the scsiport sources
from M$. I'm not sure which code from M$ you know. Our scsiport is more
compatible with the NT4.0 one. I've test many scsi controller with its
NT 4.0 drivers (adaptect 2940, ataptec on asus p2d, dmx3194uw, diamond
fireport, tekram dc390, initio a100, some with different lsi chipset,
some with initio 950 chip set). I think M$ has lost the W2K sourcesand
not the NT4.0 one. Our scsiport is very different from W2k and it is
different from NT4.0. I've add a list of imported functions. Some
functions are very specific for the implemention. ReactOS doesn't use
IoFreeMdl, IoFreeIrp, the DeviceQueu functions and some others. Many
things may nearly the same, bcause they must implement the some
functions. Our implementation is different from M$. The different
imported functions shows this. You cannot find 90% identical, if you
compare our source with the M$ source.
1. You point is GNU Asm / Microsoft Asm is Different - SO
2. I Dont use a cdrom or other media when its so easy - SO i still use floppy for small
items dont
think you know that in denmark their are taxes on the cdroms
3. Saying that microsoft uses some function witch reactos dont; i leave up to you to take
an asm
program Ida Pro 4.7 remember debug info is a good start see the exports in Winnt 4.0
Scsiport
Driver and the imports and come back to me.. then you can open your mouth once again.-
else its it
would be a waste of time writing to me
