295 operand value in *INSN and return true on success.
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:
302 movhi hi( fred ), r0, r1
303 movea lo( fred ), r1, r1
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:
308 movhi hi( fred + 0x123456 ), r0, r1
309 movea lo( fred + 0x123456 ), r1, r1
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
315 movhi hi( fred + 0x10ffff ), r0, r1
316 movea lo( fred + 0x10ffff ), r1, r1
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:
325 movhi hi( fred - 1 ), r0, r1
326 movea lo( fred - 1 ), r1, r1
328 then 0 is stored in the MOVHI instruction and -1 is stored in the
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:
338 movhi hi( fred + 0x123456 ), r0, r1
339 movea lo( fred + 0x123456 ), r1, r1
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:
345 HI16S: 0x0012 + (0x00007000 >> 16) = 0x12
346 LO16: 0x3456 + (0x00007000 & 0xffff) = 0xa456
348 but when the instructions are executed, the MOVEA instruction's value
349 is signed extended, so the sum becomes:
354 0x0011a456 but 'fred + 0x123456' = 0x0012a456
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:
359 movhi hi( fred + 0x10ffff ), r0, r1
360 movea lo( fred + 0x10ffff ), r1, r1
362 HI16S: 0x0011 + (0x00007000 >> 16) = 0x11
363 LO16: 0xffff + (0x00007000 & 0xffff) = 0x6fff
368 0x00116fff = fred + 0x10ffff = 0x7000 + 0x10ffff
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.
378 So, for example if fred is at address 0xf000:
380 movhi hi( fred + 0xffff ), r0, r1 [bit 15 of the offset is set]
381 movea lo( fred + 0xffff ), r1, r1
383 HI16S: 0x0001 + (0x0000f000 >> 16) = 0x0001
384 LO16: 0xffff + (0x0000f000 & 0xffff) = 0xefff (carry into bit 16 is lost)
389 0x0000efff but 'fred + 0xffff' = 0x0001efff
391 Similarly, if the 15th bit remains clear, but overflow occurs into
392 the 16th bit then (assuming the address of fred is 0xf000):
394 movhi hi( fred + 0x7000 ), r0, r1 [bit 15 of the offset is clear]
395 movea lo( fred + 0x7000 ), r1, r1
397 HI16S: 0x0000 + (0x0000f000 >> 16) = 0x0000
398 LO16: 0x7000 + (0x0000f000 & 0xffff) = 0x6fff (carry into bit 16 is lost)
403 0x00006fff but 'fred + 0x7000' = 0x00016fff
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:
409 movhi hi( fred + 0xffff ), r0, r1 [bit 15 of the offset is set]
410 movea lo( fred + 0xffff ), r1, r1
412 HI16S: 0x0001 + (0x00007000 >> 16)
413 LO16: 0xffff + (0x00007000 & 0xffff) = 0x6fff (carry into bit 16 is lost)
416 + 0x00006fff (bit 15 not set, so the top half is zero)
418 0x00016fff which is right (assuming that fred is at 0x7000)
420 but if the 15th bit goes from being clear to being set, then we must
421 once again handle overflow:
423 movhi hi( fred + 0x7000 ), r0, r1 [bit 15 of the offset is clear]
424 movea lo( fred + 0x7000 ), r1, r1
426 HI16S: 0x0000 + (0x0000ffff >> 16)
427 LO16: 0x7000 + (0x0000ffff & 0xffff) = 0x6fff (carry into bit 16)
430 + 0x00006fff (bit 15 not set, so the top half is zero)
432 0x00006fff which is wrong (assuming that fred is at 0xffff). */
