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