317 operand value in *INSN and return true on success.
319 The assembler has already done some of this: If the value stored in
320 the instruction has its 15th bit set, (counting from zero) then the
321 assembler will have added 1 to the value stored in the associated
322 HI16S reloc. So for example, these relocations:
324 movhi hi( fred ), r0, r1
325 movea lo( fred ), r1, r1
327 will store 0 in the value fields for the MOVHI and MOVEA instructions
328 and addend will be the address of fred, but for these instructions:
330 movhi hi( fred + 0x123456 ), r0, r1
331 movea lo( fred + 0x123456 ), r1, r1
333 the value stored in the MOVHI instruction will be 0x12 and the value
334 stored in the MOVEA instruction will be 0x3456. If however the
337 movhi hi( fred + 0x10ffff ), r0, r1
338 movea lo( fred + 0x10ffff ), r1, r1
340 then the value stored in the MOVHI instruction would be 0x11 (not
341 0x10) and the value stored in the MOVEA instruction would be 0xffff.
342 Thus (assuming for the moment that the addend is 0), at run time the
343 MOVHI instruction loads 0x110000 into r1, then the MOVEA instruction
344 adds 0xffffffff (sign extension!) producing 0x10ffff. Similarly if
345 the instructions were:
347 movhi hi( fred - 1 ), r0, r1
348 movea lo( fred - 1 ), r1, r1
350 then 0 is stored in the MOVHI instruction and -1 is stored in the
353 Overflow can occur if the addition of the value stored in the
354 instruction plus the addend sets the 15th bit when before it was clear.
355 This is because the 15th bit will be sign extended into the high part,
356 thus reducing its value by one, but since the 15th bit was originally
357 clear, the assembler will not have added 1 to the previous HI16S reloc
358 to compensate for this effect. For example:
360 movhi hi( fred + 0x123456 ), r0, r1
361 movea lo( fred + 0x123456 ), r1, r1
363 The value stored in HI16S reloc is 0x12, the value stored in the LO16
364 reloc is 0x3456. If we assume that the address of fred is 0x00007000
365 then the relocations become:
367 HI16S: 0x0012 + (0x00007000 >> 16) = 0x12
368 LO16: 0x3456 + (0x00007000 & 0xffff) = 0xa456
370 but when the instructions are executed, the MOVEA instruction's value
371 is signed extended, so the sum becomes:
376 0x0011a456 but 'fred + 0x123456' = 0x0012a456
378 Note that if the 15th bit was set in the value stored in the LO16
379 reloc, then we do not have to do anything:
381 movhi hi( fred + 0x10ffff ), r0, r1
382 movea lo( fred + 0x10ffff ), r1, r1
384 HI16S: 0x0011 + (0x00007000 >> 16) = 0x11
385 LO16: 0xffff + (0x00007000 & 0xffff) = 0x6fff
390 0x00116fff = fred + 0x10ffff = 0x7000 + 0x10ffff
392 Overflow can also occur if the computation carries into the 16th bit
393 and it also results in the 15th bit having the same value as the 15th
394 bit of the original value. What happens is that the HI16S reloc
395 will have already examined the 15th bit of the original value and
396 added 1 to the high part if the bit is set. This compensates for the
397 sign extension of 15th bit of the result of the computation. But now
398 there is a carry into the 16th bit, and this has not been allowed for.
400 So, for example if fred is at address 0xf000:
402 movhi hi( fred + 0xffff ), r0, r1 [bit 15 of the offset is set]
403 movea lo( fred + 0xffff ), r1, r1
405 HI16S: 0x0001 + (0x0000f000 >> 16) = 0x0001
406 LO16: 0xffff + (0x0000f000 & 0xffff) = 0xefff (carry into bit 16 is lost)
411 0x0000efff but 'fred + 0xffff' = 0x0001efff
413 Similarly, if the 15th bit remains clear, but overflow occurs into
414 the 16th bit then (assuming the address of fred is 0xf000):
416 movhi hi( fred + 0x7000 ), r0, r1 [bit 15 of the offset is clear]
417 movea lo( fred + 0x7000 ), r1, r1
419 HI16S: 0x0000 + (0x0000f000 >> 16) = 0x0000
420 LO16: 0x7000 + (0x0000f000 & 0xffff) = 0x6fff (carry into bit 16 is lost)
425 0x00006fff but 'fred + 0x7000' = 0x00016fff
427 Note - there is no need to change anything if a carry occurs, and the
428 15th bit changes its value from being set to being clear, as the HI16S
429 reloc will have already added in 1 to the high part for us:
431 movhi hi( fred + 0xffff ), r0, r1 [bit 15 of the offset is set]
432 movea lo( fred + 0xffff ), r1, r1
434 HI16S: 0x0001 + (0x00007000 >> 16)
435 LO16: 0xffff + (0x00007000 & 0xffff) = 0x6fff (carry into bit 16 is lost)
438 + 0x00006fff (bit 15 not set, so the top half is zero)
440 0x00016fff which is right (assuming that fred is at 0x7000)
442 but if the 15th bit goes from being clear to being set, then we must
443 once again handle overflow:
445 movhi hi( fred + 0x7000 ), r0, r1 [bit 15 of the offset is clear]
446 movea lo( fred + 0x7000 ), r1, r1
448 HI16S: 0x0000 + (0x0000ffff >> 16)
449 LO16: 0x7000 + (0x0000ffff & 0xffff) = 0x6fff (carry into bit 16)
452 + 0x00006fff (bit 15 not set, so the top half is zero)
454 0x00006fff which is wrong (assuming that fred is at 0xffff). */
