Re: GNU C++ Inline Assembler
Well, thanks:
But, I just want to use Intel-Style ASM in there. with dest, src setup.
Since I do quite a lot of Revercing and well I sometimes need to Copy
Directly from Olly/IDA into C Code.
Since that uses Intel I need the intel.
Also, Well as you saw I used Pointers to Variables in my C Code. I didnt
find a way to do that in GCC C Compiler.
I never heard of the -masm line. I am going to read up on that.
Thanks already, I hope I made my question a bit clearer now.
Cheers,
Robin
