Compiler, Assembler, Linker and Loader: A Brief Story

As a note for people linking, you also have quite a bit of control of where things are to be placed inside an executable using "linker scripts" with ld. It's actually kinda neat. For an example, here's the linker script for compiling programs for the sega-genesis.

OUTPUT_FORMAT(binary);

MEMORY
{
 rom (rx)  : org = 0, len = 0x3fffff
 io (!w!r!x) : org = 0x400000, len = 0xbf0000
 debug (!w!r!x) : org = 0xff0000, len = 0xff
 ram (w!x) : org = 0xff0100, len = 0xff00
}

SECTIONS
{
 . = 0x00;
 .text : { *(.text) }
}
