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