301 operand value in *INSN and return true on success.
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:
308 movhi hi( fred ), r0, r1
309 movea lo( fred ), r1, r1
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:
314 movhi hi( fred + 0x123456 ), r0, r1
315 movea lo( fred + 0x123456 ), r1, r1
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
321 movhi hi( fred + 0x10ffff ), r0, r1
322 movea lo( fred + 0x10ffff ), r1, r1
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:
331 movhi hi( fred - 1 ), r0, r1
332 movea lo( fred - 1 ), r1, r1
334 then 0 is stored in the MOVHI instruction and -1 is stored in the
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:
344 movhi hi( fred + 0x123456 ), r0, r1
345 movea lo( fred + 0x123456 ), r1, r1
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:
351 HI16S: 0x0012 + (0x00007000 >> 16) = 0x12
352 LO16: 0x3456 + (0x00007000 & 0xffff) = 0xa456
354 but when the instructions are executed, the MOVEA instruction's value
355 is signed extended, so the sum becomes:
360 0x0011a456 but 'fred + 0x123456' = 0x0012a456
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:
365 movhi hi( fred + 0x10ffff ), r0, r1
366 movea lo( fred + 0x10ffff ), r1, r1
368 HI16S: 0x0011 + (0x00007000 >> 16) = 0x11
369 LO16: 0xffff + (0x00007000 & 0xffff) = 0x6fff
374 0x00116fff = fred + 0x10ffff = 0x7000 + 0x10ffff
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.
384 So, for example if fred is at address 0xf000:
386 movhi hi( fred + 0xffff ), r0, r1 [bit 15 of the offset is set]
387 movea lo( fred + 0xffff ), r1, r1
389 HI16S: 0x0001 + (0x0000f000 >> 16) = 0x0001
390 LO16: 0xffff + (0x0000f000 & 0xffff) = 0xefff (carry into bit 16 is lost)
395 0x0000efff but 'fred + 0xffff' = 0x0001efff
397 Similarly, if the 15th bit remains clear, but overflow occurs into
398 the 16th bit then (assuming the address of fred is 0xf000):
400 movhi hi( fred + 0x7000 ), r0, r1 [bit 15 of the offset is clear]
401 movea lo( fred + 0x7000 ), r1, r1
403 HI16S: 0x0000 + (0x0000f000 >> 16) = 0x0000
404 LO16: 0x7000 + (0x0000f000 & 0xffff) = 0x6fff (carry into bit 16 is lost)
409 0x00006fff but 'fred + 0x7000' = 0x00016fff
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:
415 movhi hi( fred + 0xffff ), r0, r1 [bit 15 of the offset is set]
416 movea lo( fred + 0xffff ), r1, r1
418 HI16S: 0x0001 + (0x00007000 >> 16)
419 LO16: 0xffff + (0x00007000 & 0xffff) = 0x6fff (carry into bit 16 is lost)
422 + 0x00006fff (bit 15 not set, so the top half is zero)
424 0x00016fff which is right (assuming that fred is at 0x7000)
426 but if the 15th bit goes from being clear to being set, then we must
427 once again handle overflow:
429 movhi hi( fred + 0x7000 ), r0, r1 [bit 15 of the offset is clear]
430 movea lo( fred + 0x7000 ), r1, r1
432 HI16S: 0x0000 + (0x0000ffff >> 16)
433 LO16: 0x7000 + (0x0000ffff & 0xffff) = 0x6fff (carry into bit 16)
436 + 0x00006fff (bit 15 not set, so the top half is zero)
438 0x00006fff which is wrong (assuming that fred is at 0xffff). */
