How 32-Bit Everything Is Implemented

The implementation of the 32-bit everything solution affects the way global data, intrasegment references, and intersegment references are generated by the compiler and relocated by the linker. This section describes the changes that result from using this option. If you are using a low-level debugger or if your application depends on walking through jump-table entries, you need to be familiar with the details of this implementation.
