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