Where can I find documentation on assembler?
I wrote a very short program that parses a "program" using python and converts it to assembler, allowing me to compile my little proramming language to an executable. You can read my blog for more information here http://spiceycurry.blogspot.com/2010/05/simple-compilable-programming-language.html my question is... Where can I find m...
Am I Writing Assembly Or NASM?
I'm fed up with this. I've been trying to just get a grip on assembly for awhile, but I feel like I'm coding towards my compiler rather than a language. I've been using this tutorial, and so far it's giving me hell. I'm using NASM, which may be the problem, but I figured it was the most popular one. I'm simply trying to learn the most g...

How is the implicit segment register of a near pointer determined?
In section 4.3 of Intel 64® and IA-32 Architectures Software Developer's Manual. Volume 1: Basic Architecture, it says: A near pointer is a 32-bit offset ... within a segment. Near pointers are used for all memory references in a flat memory model or for references in a segmented model where the identity of the segment being accessed...
Where are the function address literals in c++?
UPDATE: After some additional reading, what I really wanted was guaranteed early binding (which should translated to an immediate call for non-virtual functions and non-PIC code), which can be done by passing a (member) function as a template parameter. The problem I had was that gcc < 4.5 and icc 11.1 can generate some funky instruction...
