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