318 operand value in *INSN and return true on success.
320 The assembler has already done some of this: If the value stored in
321 the instruction has its 15th bit set, (counting from zero) then the
322 assembler will have added 1 to the value stored in the associated
323 HI16S reloc. So for example, these relocations:
325 movhi hi( fred ), r0, r1
326 movea lo( fred ), r1, r1
328 will store 0 in the value fields for the MOVHI and MOVEA instructions
329 and addend will be the address of fred, but for these instructions:
331 movhi hi( fred + 0x123456 ), r0, r1
332 movea lo( fred + 0x123456 ), r1, r1
334 the value stored in the MOVHI instruction will be 0x12 and the value
335 stored in the MOVEA instruction will be 0x3456. If however the
338 movhi hi( fred + 0x10ffff ), r0, r1
339 movea lo( fred + 0x10ffff ), r1, r1
341 then the value stored in the MOVHI instruction would be 0x11 (not
342 0x10) and the value stored in the MOVEA instruction would be 0xffff.
343 Thus (assuming for the moment that the addend is 0), at run time the
344 MOVHI instruction loads 0x110000 into r1, then the MOVEA instruction
345 adds 0xffffffff (sign extension!) producing 0x10ffff. Similarly if
346 the instructions were:
348 movhi hi( fred - 1 ), r0, r1
349 movea lo( fred - 1 ), r1, r1
351 then 0 is stored in the MOVHI instruction and -1 is stored in the
354 Overflow can occur if the addition of the value stored in the
355 instruction plus the addend sets the 15th bit when before it was clear.
356 This is because the 15th bit will be sign extended into the high part,
357 thus reducing its value by one, but since the 15th bit was originally
358 clear, the assembler will not have added 1 to the previous HI16S reloc
359 to compensate for this effect. For example:
361 movhi hi( fred + 0x123456 ), r0, r1
362 movea lo( fred + 0x123456 ), r1, r1
364 The value stored in HI16S reloc is 0x12, the value stored in the LO16
365 reloc is 0x3456. If we assume that the address of fred is 0x00007000
366 then the relocations become:
368 HI16S: 0x0012 + (0x00007000 >> 16) = 0x12
369 LO16: 0x3456 + (0x00007000 & 0xffff) = 0xa456
371 but when the instructions are executed, the MOVEA instruction's value
372 is signed extended, so the sum becomes:
377 0x0011a456 but 'fred + 0x123456' = 0x0012a456
379 Note that if the 15th bit was set in the value stored in the LO16
380 reloc, then we do not have to do anything:
382 movhi hi( fred + 0x10ffff ), r0, r1
383 movea lo( fred + 0x10ffff ), r1, r1
385 HI16S: 0x0011 + (0x00007000 >> 16) = 0x11
386 LO16: 0xffff + (0x00007000 & 0xffff) = 0x6fff
391 0x00116fff = fred + 0x10ffff = 0x7000 + 0x10ffff
393 Overflow can also occur if the computation carries into the 16th bit
394 and it also results in the 15th bit having the same value as the 15th
395 bit of the original value. What happens is that the HI16S reloc
396 will have already examined the 15th bit of the original value and
397 added 1 to the high part if the bit is set. This compensates for the
398 sign extension of 15th bit of the result of the computation. But now
399 there is a carry into the 16th bit, and this has not been allowed for.
401 So, for example if fred is at address 0xf000:
403 movhi hi( fred + 0xffff ), r0, r1 [bit 15 of the offset is set]
404 movea lo( fred + 0xffff ), r1, r1
406 HI16S: 0x0001 + (0x0000f000 >> 16) = 0x0001
407 LO16: 0xffff + (0x0000f000 & 0xffff) = 0xefff (carry into bit 16 is lost)
412 0x0000efff but 'fred + 0xffff' = 0x0001efff
414 Similarly, if the 15th bit remains clear, but overflow occurs into
415 the 16th bit then (assuming the address of fred is 0xf000):
417 movhi hi( fred + 0x7000 ), r0, r1 [bit 15 of the offset is clear]
418 movea lo( fred + 0x7000 ), r1, r1
420 HI16S: 0x0000 + (0x0000f000 >> 16) = 0x0000
421 LO16: 0x7000 + (0x0000f000 & 0xffff) = 0x6fff (carry into bit 16 is lost)
426 0x00006fff but 'fred + 0x7000' = 0x00016fff
428 Note - there is no need to change anything if a carry occurs, and the
429 15th bit changes its value from being set to being clear, as the HI16S
430 reloc will have already added in 1 to the high part for us:
432 movhi hi( fred + 0xffff ), r0, r1 [bit 15 of the offset is set]
433 movea lo( fred + 0xffff ), r1, r1
435 HI16S: 0x0001 + (0x00007000 >> 16)
436 LO16: 0xffff + (0x00007000 & 0xffff) = 0x6fff (carry into bit 16 is lost)
439 + 0x00006fff (bit 15 not set, so the top half is zero)
441 0x00016fff which is right (assuming that fred is at 0x7000)
443 but if the 15th bit goes from being clear to being set, then we must
444 once again handle overflow:
446 movhi hi( fred + 0x7000 ), r0, r1 [bit 15 of the offset is clear]
447 movea lo( fred + 0x7000 ), r1, r1
449 HI16S: 0x0000 + (0x0000ffff >> 16)
450 LO16: 0x7000 + (0x0000ffff & 0xffff) = 0x6fff (carry into bit 16)
453 + 0x00006fff (bit 15 not set, so the top half is zero)
455 0x00006fff which is wrong (assuming that fred is at 0xffff). */
