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