From the document "" we find the following listed as used relocs:

|
|
|||
|
ABSOLUTE : The noop
|
|||
|
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
|
|||
|
branches. These represent [26|16] bit addresses.
|
|||
|
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.
