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