300 | ADDEND is the sum of the relocation symbol and offset. Store the | |
301 | operand value in *INSN and return true on success. | |
302 | ||
303 | The assembler has already done some of this: If the value stored in | |
304 | the instruction has its 15th bit set, (counting from zero) then the | |
305 | assembler will have added 1 to the value stored in the associated | |
306 | HI16S reloc. So for example, these relocations: | |
307 | ||
308 | movhi hi( fred ), r0, r1 | |
309 | movea lo( fred ), r1, r1 | |
310 | ||
311 | will store 0 in the value fields for the MOVHI and MOVEA instructions | |
312 | and addend will be the address of fred, but for these instructions: | |
313 | ||
1cd986c5 NC |
314 | movhi hi( fred + 0x123456 ), r0, r1 |
315 | movea lo( fred + 0x123456 ), r1, r1 | |
1e50d24d RS |
316 | |
317 | the value stored in the MOVHI instruction will be 0x12 and the value | |
318 | stored in the MOVEA instruction will be 0x3456. If however the | |
319 | instructions were: | |
320 | ||
1cd986c5 NC |
321 | movhi hi( fred + 0x10ffff ), r0, r1 |
322 | movea lo( fred + 0x10ffff ), r1, r1 | |
1e50d24d RS |
323 | |
324 | then the value stored in the MOVHI instruction would be 0x11 (not | |
325 | 0x10) and the value stored in the MOVEA instruction would be 0xffff. | |
326 | Thus (assuming for the moment that the addend is 0), at run time the | |
327 | MOVHI instruction loads 0x110000 into r1, then the MOVEA instruction | |
328 | adds 0xffffffff (sign extension!) producing 0x10ffff. Similarly if | |
329 | the instructions were: | |
330 | ||
1cd986c5 NC |
331 | movhi hi( fred - 1 ), r0, r1 |
332 | movea lo( fred - 1 ), r1, r1 | |
1e50d24d RS |
333 | |
334 | then 0 is stored in the MOVHI instruction and -1 is stored in the | |
335 | MOVEA instruction. | |
336 | ||
337 | Overflow can occur if the addition of the value stored in the | |
338 | instruction plus the addend sets the 15th bit when before it was clear. | |
339 | This is because the 15th bit will be sign extended into the high part, | |
340 | thus reducing its value by one, but since the 15th bit was originally | |
341 | clear, the assembler will not have added 1 to the previous HI16S reloc | |
342 | to compensate for this effect. For example: | |
343 | ||
1cd986c5 NC |
344 | movhi hi( fred + 0x123456 ), r0, r1 |
345 | movea lo( fred + 0x123456 ), r1, r1 | |
1e50d24d RS |
346 | |
347 | The value stored in HI16S reloc is 0x12, the value stored in the LO16 | |
348 | reloc is 0x3456. If we assume that the address of fred is 0x00007000 | |
349 | then the relocations become: | |
350 | ||
351 | HI16S: 0x0012 + (0x00007000 >> 16) = 0x12 | |
352 | LO16: 0x3456 + (0x00007000 & 0xffff) = 0xa456 | |
353 | ||
354 | but when the instructions are executed, the MOVEA instruction's value | |
355 | is signed extended, so the sum becomes: | |
356 | ||
357 | 0x00120000 | |
358 | + 0xffffa456 | |
359 | ------------ | |
360 | 0x0011a456 but 'fred + 0x123456' = 0x0012a456 | |
361 | ||
362 | Note that if the 15th bit was set in the value stored in the LO16 | |
363 | reloc, then we do not have to do anything: | |
364 | ||
1cd986c5 NC |
365 | movhi hi( fred + 0x10ffff ), r0, r1 |
366 | movea lo( fred + 0x10ffff ), r1, r1 | |
1e50d24d RS |
367 | |
368 | HI16S: 0x0011 + (0x00007000 >> 16) = 0x11 | |
369 | LO16: 0xffff + (0x00007000 & 0xffff) = 0x6fff | |
370 | ||
371 | 0x00110000 | |
372 | + 0x00006fff | |
373 | ------------ | |
374 | 0x00116fff = fred + 0x10ffff = 0x7000 + 0x10ffff | |
375 | ||
376 | Overflow can also occur if the computation carries into the 16th bit | |
377 | and it also results in the 15th bit having the same value as the 15th | |
378 | bit of the original value. What happens is that the HI16S reloc | |
379 | will have already examined the 15th bit of the original value and | |
380 | added 1 to the high part if the bit is set. This compensates for the | |
381 | sign extension of 15th bit of the result of the computation. But now | |
382 | there is a carry into the 16th bit, and this has not been allowed for. | |
383 | ||
384 | So, for example if fred is at address 0xf000: | |
385 | ||
1cd986c5 NC |
386 | movhi hi( fred + 0xffff ), r0, r1 [bit 15 of the offset is set] |
387 | movea lo( fred + 0xffff ), r1, r1 | |
1e50d24d RS |
388 | |
389 | HI16S: 0x0001 + (0x0000f000 >> 16) = 0x0001 | |
390 | LO16: 0xffff + (0x0000f000 & 0xffff) = 0xefff (carry into bit 16 is lost) | |
391 | ||
392 | 0x00010000 | |
393 | + 0xffffefff | |
394 | ------------ | |
395 | 0x0000efff but 'fred + 0xffff' = 0x0001efff | |
396 | ||
397 | Similarly, if the 15th bit remains clear, but overflow occurs into | |
398 | the 16th bit then (assuming the address of fred is 0xf000): | |
399 | ||
1cd986c5 NC |
400 | movhi hi( fred + 0x7000 ), r0, r1 [bit 15 of the offset is clear] |
401 | movea lo( fred + 0x7000 ), r1, r1 | |
1e50d24d RS |
402 | |
403 | HI16S: 0x0000 + (0x0000f000 >> 16) = 0x0000 | |
404 | LO16: 0x7000 + (0x0000f000 & 0xffff) = 0x6fff (carry into bit 16 is lost) | |
405 | ||
406 | 0x00000000 | |
407 | + 0x00006fff | |
408 | ------------ | |
409 | 0x00006fff but 'fred + 0x7000' = 0x00016fff | |
410 | ||
411 | Note - there is no need to change anything if a carry occurs, and the | |
412 | 15th bit changes its value from being set to being clear, as the HI16S | |
413 | reloc will have already added in 1 to the high part for us: | |
414 | ||
1cd986c5 NC |
415 | movhi hi( fred + 0xffff ), r0, r1 [bit 15 of the offset is set] |
416 | movea lo( fred + 0xffff ), r1, r1 | |
1e50d24d RS |
417 | |
418 | HI16S: 0x0001 + (0x00007000 >> 16) | |
419 | LO16: 0xffff + (0x00007000 & 0xffff) = 0x6fff (carry into bit 16 is lost) | |
420 | ||
421 | 0x00010000 | |
422 | + 0x00006fff (bit 15 not set, so the top half is zero) | |
423 | ------------ | |
424 | 0x00016fff which is right (assuming that fred is at 0x7000) | |
425 | ||
426 | but if the 15th bit goes from being clear to being set, then we must | |
427 | once again handle overflow: | |
428 | ||
1cd986c5 NC |
429 | movhi hi( fred + 0x7000 ), r0, r1 [bit 15 of the offset is clear] |
430 | movea lo( fred + 0x7000 ), r1, r1 | |
1e50d24d RS |
431 | |
432 | HI16S: 0x0000 + (0x0000ffff >> 16) | |
433 | LO16: 0x7000 + (0x0000ffff & 0xffff) = 0x6fff (carry into bit 16) | |
434 | ||
435 | 0x00000000 | |
436 | + 0x00006fff (bit 15 not set, so the top half is zero) | |
437 | ------------ | |
438 | 0x00006fff which is wrong (assuming that fred is at 0xffff). */ | |
