283 /* About the relocation formatting table...
285 There are 256 entries in the table, one for each possible
286 relocation opcode available in SOM. We index the table by
287 the relocation opcode. The names and operations are those
288 defined by a.out_800 (4).
290 Right now this table is only used to count and perform minimal
291 processing on relocation streams so that they can be internalized
292 into BFD and symbolically printed by utilities. To make actual use
293 of them would be much more difficult, BFD's concept of relocations
294 is far too simple to handle SOM relocations. The basic assumption
295 that a relocation can be completely processed independent of other
296 relocations before an object file is written is invalid for SOM.
298 The SOM relocations are meant to be processed as a stream, they
299 specify copying of data from the input section to the output section
300 while possibly modifying the data in some manner. They also can
301 specify that a variable number of zeros or uninitialized data be
302 inserted on in the output segment at the current offset. Some
303 relocations specify that some previous relocation be re-applied at
304 the current location in the input/output sections. And finally a number
305 of relocations have effects on other sections (R_ENTRY, R_EXIT,
306 R_UNWIND_AUX and a variety of others). There isn't even enough room
307 in the BFD relocation data structure to store enough information to
308 perform all the relocations.
310 Each entry in the table has three fields.
312 The first entry is an index into this "class" of relocations. This
313 index can then be used as a variable within the relocation itself.
315 The second field is a format string which actually controls processing
316 of the relocation. It uses a simple postfix machine to do calculations
317 based on variables/constants found in the string and the relocation
320 The third field specifys whether or not this relocation may use
321 a constant (V) from the previous R_DATA_OVERRIDE rather than a constant
322 stored in the instruction.
326 L = input space byte count
327 D = index into class of relocations
328 M = output space byte count
329 N = statement number (unused?)
331 R = parameter relocation bits
333 T = first 32 bits of stack unwind information
334 U = second 32 bits of stack unwind information
335 V = a literal constant (usually used in the next relocation)
336 P = a previous relocation
338 Lower case letters (starting with 'b') refer to following
339 bytes in the relocation stream. 'b' is the next 1 byte,
340 c is the next 2 bytes, d is the next 3 bytes, etc...
341 This is the variable part of the relocation entries that
342 makes our life a living hell.
344 numerical constants are also used in the format string. Note
345 the constants are represented in decimal.
347 '+', "*" and "=" represents the obvious postfix operators.
348 '<' represents a left shift.
352 Parameter Relocation Bits:
356 Previous Relocations: The index field represents which in the queue
357 of 4 previous fixups should be re-applied.
359 Literal Constants: These are generally used to represent addend
360 parts of relocations when these constants are not stored in the
361 fields of the instructions themselves. For example the instruction
362 addil foo-$global$-0x1234 would use an override for "0x1234" rather
363 than storing it into the addil itself. */
