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