190 /* About the relocation formatting table...
192 There are 256 entries in the table, one for each possible
193 relocation opcode available in SOM. We index the table by
194 the relocation opcode. The names and operations are those
195 defined by a.out_800 (4).
197 Right now this table is only used to count and perform minimal
198 processing on relocation streams so that they can be internalized
199 into BFD and symbolically printed by utilities. To make actual use
200 of them would be much more difficult, BFD's concept of relocations
201 is far too simple to handle SOM relocations. The basic assumption
202 that a relocation can be completely processed independent of other
203 relocations before an object file is written is invalid for SOM.
205 The SOM relocations are meant to be processed as a stream, they
206 specify copying of data from the input section to the output section
207 while possibly modifying the data in some manner. They also can
208 specify that a variable number of zeros or uninitialized data be
209 inserted on in the output segment at the current offset. Some
210 relocations specify that some previous relocation be re-applied at
211 the current location in the input/output sections. And finally a number
212 of relocations have effects on other sections (R_ENTRY, R_EXIT,
213 R_UNWIND_AUX and a variety of others). There isn't even enough room
214 in the BFD relocation data structure to store enough information to
215 perform all the relocations.
217 Each entry in the table has three fields.
219 The first entry is an index into this "class" of relocations. This
220 index can then be used as a variable within the relocation itself.
222 The second field is a format string which actually controls processing
223 of the relocation. It uses a simple postfix machine to do calculations
224 based on variables/constants found in the string and the relocation
227 The third field specifys whether or not this relocation may use
228 a constant (V) from the previous R_DATA_OVERRIDE rather than a constant
229 stored in the instruction.
233 L = input space byte count
234 D = index into class of relocations
235 M = output space byte count
236 N = statement number (unused?)
238 R = parameter relocation bits
240 T = first 32 bits of stack unwind information
241 U = second 32 bits of stack unwind information
242 V = a literal constant (usually used in the next relocation)
243 P = a previous relocation
245 Lower case letters (starting with 'b') refer to following
246 bytes in the relocation stream. 'b' is the next 1 byte,
247 c is the next 2 bytes, d is the next 3 bytes, etc...
248 This is the variable part of the relocation entries that
249 makes our life a living hell.
251 numerical constants are also used in the format string. Note
252 the constants are represented in decimal.
254 '+', "*" and "=" represents the obvious postfix operators.
255 '<' represents a left shift.
259 Parameter Relocation Bits:
263 Previous Relocations: The index field represents which in the queue
264 of 4 previous fixups should be re-applied.
266 Literal Constants: These are generally used to represent addend
267 parts of relocations when these constants are not stored in the
268 fields of the instructions themselves. For example the instruction
269 addil foo-$global$-0x1234 would use an override for "0x1234" rather
270 than storing it into the addil itself. */
