- ADDR[64|32|16] : fields that hold addresses in data fields or the
- 16 bit displacement field on a load/store.
- ADDR[24|14] : fields that hold addresses in branch and cond

- The low order 2 bits are preserved.
- REL[24|14] : branches relative to the Instruction Address
- register. These represent [26|16] bit addresses,
- as before. The instruction field will be zero, and
- the address of the SYM will be inserted at link time.
- TOCREL16 : 16 bit displacement field referring to a slot in
- toc.
- TOCREL14 : 16 bit displacement field, similar to REL14 or ADDR14.
- ADDR32NB : 32 bit address relative to the virtual origin.
- (On the alpha, this is always a linker generated thunk)
- (i.e. 32bit addr relative to the image base)
- SECREL : The value is relative to the start of the section
- containing the symbol.
- SECTION : access to the header containing the item. Supports the
- codeview debugger.

- In particular, note that the document does not indicate that the
- relocations listed in the header file are used. */
