-/* About the relocation formatting table...
-
- There are 256 entries in the table, one for each possible
- relocation opcode available in SOM. We index the table by
- the relocation opcode. The names and operations are those
- defined by a.out_800 (4).
-
- Right now this table is only used to count and perform minimal
- processing on relocation streams so that they can be internalized
- into BFD and symbolically printed by utilities. To make actual use
- of them would be much more difficult, BFD's concept of relocations
- is far too simple to handle SOM relocations. The basic assumption
- that a relocation can be completely processed independent of other
- relocations before an object file is written is invalid for SOM.
-
- The SOM relocations are meant to be processed as a stream, they
- specify copying of data from the input section to the output section
- while possibly modifying the data in some manner. They also can
- specify that a variable number of zeros or uninitialized data be
- inserted on in the output segment at the current offset. Some
- relocations specify that some previous relocation be re-applied at
- the current location in the input/output sections. And finally a number
- of relocations have effects on other sections (R_ENTRY, R_EXIT,
- R_UNWIND_AUX and a variety of others). There isn't even enough room
- in the BFD relocation data structure to store enough information to
- perform all the relocations.
-
- Each entry in the table has three fields.
-
- The first entry is an index into this "class" of relocations. This
- index can then be used as a variable within the relocation itself.
-
- The second field is a format string which actually controls processing
- of the relocation. It uses a simple postfix machine to do calculations
- based on variables/constants found in the string and the relocation
- stream.
-
- The third field specifys whether or not this relocation may use
- a constant (V) from the previous R_DATA_OVERRIDE rather than a constant
- stored in the instruction.
-
- Variables:
-
- L = input space byte count
- D = index into class of relocations
- M = output space byte count
- N = statement number (unused?)
- O = stack operation
- R = parameter relocation bits
- S = symbol index
- T = first 32 bits of stack unwind information
- U = second 32 bits of stack unwind information
- V = a literal constant (usually used in the next relocation)
- P = a previous relocation
-
- Lower case letters (starting with 'b') refer to following
- bytes in the relocation stream. 'b' is the next 1 byte,
- c is the next 2 bytes, d is the next 3 bytes, etc...
- This is the variable part of the relocation entries that
- makes our life a living hell.
-
- numerical constants are also used in the format string. Note
- the constants are represented in decimal.
-
- '+', "*" and "=" represents the obvious postfix operators.
- '<' represents a left shift.
-
- Stack Operations:
-
- Parameter Relocation Bits:
-
- Unwind Entries:
-
- Previous Relocations: The index field represents which in the queue
- of 4 previous fixups should be re-applied.
-
- Literal Constants: These are generally used to represent addend
- parts of relocations when these constants are not stored in the
- fields of the instructions themselves. For example the instruction
- addil foo-$global$-0x1234 would use an override for "0x1234" rather
- than storing it into the addil itself. */
