I realize that this question is impossible to answer absolutely, but I'm only after ballpark figures:
Given a reasonably sized C-program (thousands of lines of code), on average, how many ASM-instructions would be generated. In other words, what's a realistic...

Statements like i++; can translate to a single INC AX .
That varies tremendously! I woudn't believe anyone if they tried to offer a rough conversion .

Lets say we have an average of one page fault every 20,000,000 instructions, a normal instruction takes 2 nanoseconds, and a page fault causes the instruction to take an additional 10 milliseconds. What is the average instruction time, taking page faults...
Answer Snippets (Read the full thread at stackoverflow):
20,000,000 instructions, one of them will page-fault
Therefore, the 20,000,000 instructions will take
(2 nanoseconds * 20,000,000) + 10 milliseconds
get the result (which is the total ....
2.5 nanoseconds? Pretty simple arithmetic, I guess.

Do graphic cards have instruction sets of their own? I assume they do, but I have been wondering if it is proprietary or if there is some sort of open standard.
Is every GPU instruction preceded by a CPU instruction or is it seamless? That is does OpenGL...

AMD does even provide the specification up to the HD4000 series at the moment .
Yes they do.
The GPU instructions are executed independent from the CPU instructions.
Yes, the GPU have their own proprietrary instruction sets.

Is there CIL instruction to exchange the first two elements in the stack?

Answer Snippets (Read the full thread at stackoverflow):
Looking at a list of CIL instructions there doesn't appear to be a single instruction that exchanges....
However, using stloc , pop , and ldloc , you should be able to accomplish your exchange .
There is no single instruction exchange.

Hi Does iphone processor ARMV6 supports MMX instructions?

Answer Snippets (Read the full thread at stackoverflow):
ARMs are a bit configurable....
The iPhone uses an ARM processor so you can't use MMX .
MMX is a SIMD instruction set for x86.
Looks like ARMV6 has a SIMD unit of some kind.. .

If the program counter points to the address of the next instruction to be executed, what do frame pointers do?
Answer Snippets (Read the full thread at stackoverflow):
This is very implementation dependent (and more....
The point is that the frame pointer is fixed during the life of a method while the stack pointer could move during execution .
Usually the return address (but sometimes just past last argument, for example) .

This is definitely obsessive, but I am fascinated by how cleverly the compiler translates C code into machine instructions. Since I am a little fuzzy on some instructions, it would be helpful if I could watch the operation of a compiled program at the...

Then use Run/Step into(over) instruction to step in assembly.
Wait till you hit a breakpoint.
In the Debugger window, enable assembly: Run/Debugger display/Source and disassembly .

No, it's a transaction control (TCL) statement, not a data manipulation (DML) statement .

What kind of scenarios can XSL processing instructions be used or applied? When is it good or bad to use them?
Clean slate here, I don't have a good handle on this particular element.

I myself have never actually found a use for them, so if you don't understand them, you probably don't need 'em .
Processing instructions let you insert things like <?php ?> or <?xml ?> into the output code.

I have the first edition of the book, the second edition is now current .
I can only partially answer the question: I'd recommend See MIPS Run by Dominic Sweetman, if you're not already referring to it .
