296 | ADDEND is the sum of the relocation symbol and offset. Store the | |
297 | operand value in *INSN and return true on success. | |
298 | ||
299 | The assembler has already done some of this: If the value stored in | |
300 | the instruction has its 15th bit set, (counting from zero) then the | |
301 | assembler will have added 1 to the value stored in the associated | |
302 | HI16S reloc. So for example, these relocations: | |
303 | ||
304 | movhi hi( fred ), r0, r1 | |
305 | movea lo( fred ), r1, r1 | |
306 | ||
307 | will store 0 in the value fields for the MOVHI and MOVEA instructions | |
308 | and addend will be the address of fred, but for these instructions: | |
309 | ||
1cd986c5 NC |
310 | movhi hi( fred + 0x123456 ), r0, r1 |
311 | movea lo( fred + 0x123456 ), r1, r1 | |
1e50d24d RS |
312 | |
313 | the value stored in the MOVHI instruction will be 0x12 and the value | |
314 | stored in the MOVEA instruction will be 0x3456. If however the | |
315 | instructions were: | |
316 | ||
1cd986c5 NC |
317 | movhi hi( fred + 0x10ffff ), r0, r1 |
318 | movea lo( fred + 0x10ffff ), r1, r1 | |
1e50d24d RS |
319 | |
320 | then the value stored in the MOVHI instruction would be 0x11 (not | |
321 | 0x10) and the value stored in the MOVEA instruction would be 0xffff. | |
322 | Thus (assuming for the moment that the addend is 0), at run time the | |
323 | MOVHI instruction loads 0x110000 into r1, then the MOVEA instruction | |
324 | adds 0xffffffff (sign extension!) producing 0x10ffff. Similarly if | |
325 | the instructions were: | |
326 | ||
1cd986c5 NC |
327 | movhi hi( fred - 1 ), r0, r1 |
328 | movea lo( fred - 1 ), r1, r1 | |
1e50d24d RS |
329 | |
330 | then 0 is stored in the MOVHI instruction and -1 is stored in the | |
331 | MOVEA instruction. | |
332 | ||
333 | Overflow can occur if the addition of the value stored in the | |
334 | instruction plus the addend sets the 15th bit when before it was clear. | |
335 | This is because the 15th bit will be sign extended into the high part, | |
336 | thus reducing its value by one, but since the 15th bit was originally | |
337 | clear, the assembler will not have added 1 to the previous HI16S reloc | |
338 | to compensate for this effect. For example: | |
339 | ||
1cd986c5 NC |
340 | movhi hi( fred + 0x123456 ), r0, r1 |
341 | movea lo( fred + 0x123456 ), r1, r1 | |
1e50d24d RS |
342 | |
343 | The value stored in HI16S reloc is 0x12, the value stored in the LO16 | |
344 | reloc is 0x3456. If we assume that the address of fred is 0x00007000 | |
345 | then the relocations become: | |
346 | ||
347 | HI16S: 0x0012 + (0x00007000 >> 16) = 0x12 | |
348 | LO16: 0x3456 + (0x00007000 & 0xffff) = 0xa456 | |
349 | ||
350 | but when the instructions are executed, the MOVEA instruction's value | |
351 | is signed extended, so the sum becomes: | |
352 | ||
353 | 0x00120000 | |
354 | + 0xffffa456 | |
355 | ------------ | |
356 | 0x0011a456 but 'fred + 0x123456' = 0x0012a456 | |
357 | ||
358 | Note that if the 15th bit was set in the value stored in the LO16 | |
359 | reloc, then we do not have to do anything: | |
360 | ||
1cd986c5 NC |
361 | movhi hi( fred + 0x10ffff ), r0, r1 |
362 | movea lo( fred + 0x10ffff ), r1, r1 | |
1e50d24d RS |
363 | |
364 | HI16S: 0x0011 + (0x00007000 >> 16) = 0x11 | |
365 | LO16: 0xffff + (0x00007000 & 0xffff) = 0x6fff | |
366 | ||
367 | 0x00110000 | |
368 | + 0x00006fff | |
369 | ------------ | |
370 | 0x00116fff = fred + 0x10ffff = 0x7000 + 0x10ffff | |
371 | ||
372 | Overflow can also occur if the computation carries into the 16th bit | |
373 | and it also results in the 15th bit having the same value as the 15th | |
374 | bit of the original value. What happens is that the HI16S reloc | |
375 | will have already examined the 15th bit of the original value and | |
376 | added 1 to the high part if the bit is set. This compensates for the | |
377 | sign extension of 15th bit of the result of the computation. But now | |
378 | there is a carry into the 16th bit, and this has not been allowed for. | |
379 | ||
380 | So, for example if fred is at address 0xf000: | |
381 | ||
1cd986c5 NC |
382 | movhi hi( fred + 0xffff ), r0, r1 [bit 15 of the offset is set] |
383 | movea lo( fred + 0xffff ), r1, r1 | |
1e50d24d RS |
384 | |
385 | HI16S: 0x0001 + (0x0000f000 >> 16) = 0x0001 | |
386 | LO16: 0xffff + (0x0000f000 & 0xffff) = 0xefff (carry into bit 16 is lost) | |
387 | ||
388 | 0x00010000 | |
389 | + 0xffffefff | |
390 | ------------ | |
391 | 0x0000efff but 'fred + 0xffff' = 0x0001efff | |
392 | ||
393 | Similarly, if the 15th bit remains clear, but overflow occurs into | |
394 | the 16th bit then (assuming the address of fred is 0xf000): | |
395 | ||
1cd986c5 NC |
396 | movhi hi( fred + 0x7000 ), r0, r1 [bit 15 of the offset is clear] |
397 | movea lo( fred + 0x7000 ), r1, r1 | |
1e50d24d RS |
398 | |
399 | HI16S: 0x0000 + (0x0000f000 >> 16) = 0x0000 | |
400 | LO16: 0x7000 + (0x0000f000 & 0xffff) = 0x6fff (carry into bit 16 is lost) | |
401 | ||
402 | 0x00000000 | |
403 | + 0x00006fff | |
404 | ------------ | |
405 | 0x00006fff but 'fred + 0x7000' = 0x00016fff | |
406 | ||
407 | Note - there is no need to change anything if a carry occurs, and the | |
408 | 15th bit changes its value from being set to being clear, as the HI16S | |
409 | reloc will have already added in 1 to the high part for us: | |
410 | ||
1cd986c5 NC |
411 | movhi hi( fred + 0xffff ), r0, r1 [bit 15 of the offset is set] |
412 | movea lo( fred + 0xffff ), r1, r1 | |
1e50d24d RS |
413 | |
414 | HI16S: 0x0001 + (0x00007000 >> 16) | |
415 | LO16: 0xffff + (0x00007000 & 0xffff) = 0x6fff (carry into bit 16 is lost) | |
416 | ||
417 | 0x00010000 | |
418 | + 0x00006fff (bit 15 not set, so the top half is zero) | |
419 | ------------ | |
420 | 0x00016fff which is right (assuming that fred is at 0x7000) | |
421 | ||
422 | but if the 15th bit goes from being clear to being set, then we must | |
423 | once again handle overflow: | |
424 | ||
1cd986c5 NC |
425 | movhi hi( fred + 0x7000 ), r0, r1 [bit 15 of the offset is clear] |
426 | movea lo( fred + 0x7000 ), r1, r1 | |
1e50d24d RS |
427 | |
428 | HI16S: 0x0000 + (0x0000ffff >> 16) | |
429 | LO16: 0x7000 + (0x0000ffff & 0xffff) = 0x6fff (carry into bit 16) | |
430 | ||
431 | 0x00000000 | |
432 | + 0x00006fff (bit 15 not set, so the top half is zero) | |
433 | ------------ | |
434 | 0x00006fff which is wrong (assuming that fred is at 0xffff). */ | |
