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