294 ADDEND is the sum of the relocation symbol and offset. Store the
295 operand value in *INSN and return true on success.
296
297 The assembler has already done some of this: If the value stored in
298 the instruction has its 15th bit set, (counting from zero) then the
299 assembler will have added 1 to the value stored in the associated
300 HI16S reloc. So for example, these relocations:
301
302 movhi hi( fred ), r0, r1
303 movea lo( fred ), r1, r1
304
305 will store 0 in the value fields for the MOVHI and MOVEA instructions
306 and addend will be the address of fred, but for these instructions:
307
1cd986c5
NC
308 movhi hi( fred + 0x123456 ), r0, r1
309 movea lo( fred + 0x123456 ), r1, r1
1e50d24d
RS
310
311 the value stored in the MOVHI instruction will be 0x12 and the value
312 stored in the MOVEA instruction will be 0x3456. If however the
313 instructions were:
314
1cd986c5
NC
315 movhi hi( fred + 0x10ffff ), r0, r1
316 movea lo( fred + 0x10ffff ), r1, r1
1e50d24d
RS
317
318 then the value stored in the MOVHI instruction would be 0x11 (not
319 0x10) and the value stored in the MOVEA instruction would be 0xffff.
320 Thus (assuming for the moment that the addend is 0), at run time the
321 MOVHI instruction loads 0x110000 into r1, then the MOVEA instruction
322 adds 0xffffffff (sign extension!) producing 0x10ffff. Similarly if
323 the instructions were:
324
1cd986c5
NC
325 movhi hi( fred - 1 ), r0, r1
326 movea lo( fred - 1 ), r1, r1
1e50d24d
RS
327
328 then 0 is stored in the MOVHI instruction and -1 is stored in the
329 MOVEA instruction.
330
331 Overflow can occur if the addition of the value stored in the
332 instruction plus the addend sets the 15th bit when before it was clear.
333 This is because the 15th bit will be sign extended into the high part,
334 thus reducing its value by one, but since the 15th bit was originally
335 clear, the assembler will not have added 1 to the previous HI16S reloc
336 to compensate for this effect. For example:
337
1cd986c5
NC
338 movhi hi( fred + 0x123456 ), r0, r1
339 movea lo( fred + 0x123456 ), r1, r1
1e50d24d
RS
340
341 The value stored in HI16S reloc is 0x12, the value stored in the LO16
342 reloc is 0x3456. If we assume that the address of fred is 0x00007000
343 then the relocations become:
344
345 HI16S: 0x0012 + (0x00007000 >> 16) = 0x12
346 LO16: 0x3456 + (0x00007000 & 0xffff) = 0xa456
347
348 but when the instructions are executed, the MOVEA instruction's value
349 is signed extended, so the sum becomes:
350
351 0x00120000
352 + 0xffffa456
353 ------------
354 0x0011a456 but 'fred + 0x123456' = 0x0012a456
355
356 Note that if the 15th bit was set in the value stored in the LO16
357 reloc, then we do not have to do anything:
358
1cd986c5
NC
359 movhi hi( fred + 0x10ffff ), r0, r1
360 movea lo( fred + 0x10ffff ), r1, r1
1e50d24d
RS
361
362 HI16S: 0x0011 + (0x00007000 >> 16) = 0x11
363 LO16: 0xffff + (0x00007000 & 0xffff) = 0x6fff
364
365 0x00110000
366 + 0x00006fff
367 ------------
368 0x00116fff = fred + 0x10ffff = 0x7000 + 0x10ffff
369
370 Overflow can also occur if the computation carries into the 16th bit
371 and it also results in the 15th bit having the same value as the 15th
372 bit of the original value. What happens is that the HI16S reloc
373 will have already examined the 15th bit of the original value and
374 added 1 to the high part if the bit is set. This compensates for the
375 sign extension of 15th bit of the result of the computation. But now
376 there is a carry into the 16th bit, and this has not been allowed for.
377
378 So, for example if fred is at address 0xf000:
379
1cd986c5
NC
380 movhi hi( fred + 0xffff ), r0, r1 [bit 15 of the offset is set]
381 movea lo( fred + 0xffff ), r1, r1
1e50d24d
RS
382
383 HI16S: 0x0001 + (0x0000f000 >> 16) = 0x0001
384 LO16: 0xffff + (0x0000f000 & 0xffff) = 0xefff (carry into bit 16 is lost)
385
386 0x00010000
387 + 0xffffefff
388 ------------
389 0x0000efff but 'fred + 0xffff' = 0x0001efff
390
391 Similarly, if the 15th bit remains clear, but overflow occurs into
392 the 16th bit then (assuming the address of fred is 0xf000):
393
1cd986c5
NC
394 movhi hi( fred + 0x7000 ), r0, r1 [bit 15 of the offset is clear]
395 movea lo( fred + 0x7000 ), r1, r1
1e50d24d
RS
396
397 HI16S: 0x0000 + (0x0000f000 >> 16) = 0x0000
398 LO16: 0x7000 + (0x0000f000 & 0xffff) = 0x6fff (carry into bit 16 is lost)
399
400 0x00000000
401 + 0x00006fff
402 ------------
403 0x00006fff but 'fred + 0x7000' = 0x00016fff
404
405 Note - there is no need to change anything if a carry occurs, and the
406 15th bit changes its value from being set to being clear, as the HI16S
407 reloc will have already added in 1 to the high part for us:
