282 /* About the relocation formatting table...
284 There are 256 entries in the table, one for each possible
285 relocation opcode available in SOM. We index the table by
286 the relocation opcode. The names and operations are those
287 defined by a.out_800 (4).
289 Right now this table is only used to count and perform minimal
290 processing on relocation streams so that they can be internalized
291 into BFD and symbolically printed by utilities. To make actual use
292 of them would be much more difficult, BFD's concept of relocations
293 is far too simple to handle SOM relocations. The basic assumption
294 that a relocation can be completely processed independent of other
295 relocations before an object file is written is invalid for SOM.
297 The SOM relocations are meant to be processed as a stream, they
298 specify copying of data from the input section to the output section
299 while possibly modifying the data in some manner. They also can
300 specify that a variable number of zeros or uninitialized data be
301 inserted on in the output segment at the current offset. Some
302 relocations specify that some previous relocation be re-applied at
303 the current location in the input/output sections. And finally a number
304 of relocations have effects on other sections (R_ENTRY, R_EXIT,
305 R_UNWIND_AUX and a variety of others). There isn't even enough room
306 in the BFD relocation data structure to store enough information to
307 perform all the relocations.
309 Each entry in the table has three fields.
311 The first entry is an index into this "class" of relocations. This
312 index can then be used as a variable within the relocation itself.
314 The second field is a format string which actually controls processing
315 of the relocation. It uses a simple postfix machine to do calculations
316 based on variables/constants found in the string and the relocation
319 The third field specifys whether or not this relocation may use
320 a constant (V) from the previous R_DATA_OVERRIDE rather than a constant
321 stored in the instruction.
325 L = input space byte count
326 D = index into class of relocations
327 M = output space byte count
328 N = statement number (unused?)
330 R = parameter relocation bits
332 U = 64 bits of stack unwind and frame size info (we only keep 32 bits)
333 V = a literal constant (usually used in the next relocation)
334 P = a previous relocation
336 Lower case letters (starting with 'b') refer to following
337 bytes in the relocation stream. 'b' is the next 1 byte,
338 c is the next 2 bytes, d is the next 3 bytes, etc...
339 This is the variable part of the relocation entries that
340 makes our life a living hell.
342 numerical constants are also used in the format string. Note
343 the constants are represented in decimal.
345 '+', "*" and "=" represents the obvious postfix operators.
346 '<' represents a left shift.
350 Parameter Relocation Bits:
354 Previous Relocations: The index field represents which in the queue
355 of 4 previous fixups should be re-applied.
357 Literal Constants: These are generally used to represent addend
358 parts of relocations when these constants are not stored in the
359 fields of the instructions themselves. For example the instruction
360 addil foo-$global$-0x1234 would use an override for "0x1234" rather
361 than storing it into the addil itself. */
