x86 Portable Files

Public Domain

x86 Portable is just a NASM include header file that adds
automatically-sized instructions and registers for word/dword/qword/wideword
according to the target x86 CPU, you just need to specify the word size
through _x86_Portable__PLATFORMBITS_ (1632 for 386 Real Mode,
16 for 8086/8088 Real Mode, 32 for 32-bit mode and 64 for 64-bit mode).

With that you can think about how to create code that will use
the full registers automatically for all operation modes
instead of trying to generate or write dirty and highly
non-portable assembly sources.
