Is Effective Address == address_of ?

You didn't seriously believe anybody would be able to answer that one without more information about the context you ran into this question in, did you?

Even if all the snow were burnt, ashes would remain.

Effective address is the address computed after performing complete addressing mode arithmatic.

You will find many compilers using a load effective address instruction when you use address of (&) in C code.

Sometimes the compilers also use (misuse?) load effective address to load small integer constants and perform simple interger aritmatic. As it turns out to be faster than using the regular integer mechanisms.

This is particularly true in the 68000 family.

Thanks Sandeep,

I had guessed as much from what my compiler is doing but could not find a straight definition on Google; only passing comments within complicated descriptions of something else.
