291 | /* About the relocation formatting table... |
292 | ||
293 | There are 256 entries in the table, one for each possible | |
294 | relocation opcode available in SOM. We index the table by | |
295 | the relocation opcode. The names and operations are those | |
296 | defined by a.out_800 (4). | |
297 | ||
298 | Right now this table is only used to count and perform minimal | |
299 | processing on relocation streams so that they can be internalized | |
300 | into BFD and symbolically printed by utilities. To make actual use | |
301 | of them would be much more difficult, BFD's concept of relocations | |
302 | is far too simple to handle SOM relocations. The basic assumption | |
303 | that a relocation can be completely processed independent of other | |
304 | relocations before an object file is written is invalid for SOM. | |
305 | ||
306 | The SOM relocations are meant to be processed as a stream, they | |
307 | specify copying of data from the input section to the output section | |
308 | while possibly modifying the data in some manner. They also can | |
309 | specify that a variable number of zeros or uninitialized data be | |
310 | inserted on in the output segment at the current offset. Some | |
311 | relocations specify that some previous relocation be re-applied at | |
312 | the current location in the input/output sections. And finally a number | |
313 | of relocations have effects on other sections (R_ENTRY, R_EXIT, | |
314 | R_UNWIND_AUX and a variety of others). There isn't even enough room | |
315 | in the BFD relocation data structure to store enough information to | |
316 | perform all the relocations. | |
317 | ||
318 | Each entry in the table has three fields. | |
319 | ||
320 | The first entry is an index into this "class" of relocations. This | |
321 | index can then be used as a variable within the relocation itself. | |
322 | ||
323 | The second field is a format string which actually controls processing | |
324 | of the relocation. It uses a simple postfix machine to do calculations | |
325 | based on variables/constants found in the string and the relocation | |
326 | stream. | |
327 | ||
328 | The third field specifys whether or not this relocation may use | |
329 | a constant (V) from the previous R_DATA_OVERRIDE rather than a constant | |
330 | stored in the instruction. | |
331 | ||
332 | Variables: | |
333 | ||
334 | L = input space byte count | |
335 | D = index into class of relocations | |
336 | M = output space byte count | |
337 | N = statement number (unused?) | |
338 | O = stack operation | |
339 | R = parameter relocation bits | |
340 | S = symbol index | |
ae880afc JL |
341 | T = first 32 bits of stack unwind information |
342 | U = second 32 bits of stack unwind information | |
36456a67 JL |
343 | V = a literal constant (usually used in the next relocation) |
344 | P = a previous relocation | |
345 | ||
346 | Lower case letters (starting with 'b') refer to following | |
347 | bytes in the relocation stream. 'b' is the next 1 byte, | |
348 | c is the next 2 bytes, d is the next 3 bytes, etc... | |
349 | This is the variable part of the relocation entries that | |
350 | makes our life a living hell. | |
351 | ||
352 | numerical constants are also used in the format string. Note | |
353 | the constants are represented in decimal. | |
354 | ||
355 | '+', "*" and "=" represents the obvious postfix operators. | |
356 | '<' represents a left shift. | |
357 | ||
358 | Stack Operations: | |
359 | ||
360 | Parameter Relocation Bits: | |
361 | ||
362 | Unwind Entries: | |
363 | ||
364 | Previous Relocations: The index field represents which in the queue | |
365 | of 4 previous fixups should be re-applied. | |
366 | ||
367 | Literal Constants: These are generally used to represent addend | |
368 | parts of relocations when these constants are not stored in the | |
369 | fields of the instructions themselves. For example the instruction | |
370 | addil foo-$global$-0x1234 would use an override for "0x1234" rather | |
371 | than storing it into the addil itself. */ | |
