297 operand value in *INSN and return true on success.
299 The assembler has already done some of this: If the value stored in
300 the instruction has its 15th bit set, (counting from zero) then the
301 assembler will have added 1 to the value stored in the associated
302 HI16S reloc. So for example, these relocations:
304 movhi hi( fred ), r0, r1
305 movea lo( fred ), r1, r1
307 will store 0 in the value fields for the MOVHI and MOVEA instructions
308 and addend will be the address of fred, but for these instructions:
310 movhi hi( fred + 0x123456 ), r0, r1
311 movea lo( fred + 0x123456 ), r1, r1
313 the value stored in the MOVHI instruction will be 0x12 and the value
314 stored in the MOVEA instruction will be 0x3456. If however the
317 movhi hi( fred + 0x10ffff ), r0, r1
318 movea lo( fred + 0x10ffff ), r1, r1
320 then the value stored in the MOVHI instruction would be 0x11 (not
321 0x10) and the value stored in the MOVEA instruction would be 0xffff.
322 Thus (assuming for the moment that the addend is 0), at run time the
323 MOVHI instruction loads 0x110000 into r1, then the MOVEA instruction
324 adds 0xffffffff (sign extension!) producing 0x10ffff. Similarly if
325 the instructions were:
327 movhi hi( fred - 1 ), r0, r1
328 movea lo( fred - 1 ), r1, r1
330 then 0 is stored in the MOVHI instruction and -1 is stored in the
333 Overflow can occur if the addition of the value stored in the
334 instruction plus the addend sets the 15th bit when before it was clear.
335 This is because the 15th bit will be sign extended into the high part,
336 thus reducing its value by one, but since the 15th bit was originally
337 clear, the assembler will not have added 1 to the previous HI16S reloc
338 to compensate for this effect. For example:
340 movhi hi( fred + 0x123456 ), r0, r1
341 movea lo( fred + 0x123456 ), r1, r1
343 The value stored in HI16S reloc is 0x12, the value stored in the LO16
344 reloc is 0x3456. If we assume that the address of fred is 0x00007000
345 then the relocations become:
347 HI16S: 0x0012 + (0x00007000 >> 16) = 0x12
348 LO16: 0x3456 + (0x00007000 & 0xffff) = 0xa456
350 but when the instructions are executed, the MOVEA instruction's value
351 is signed extended, so the sum becomes:
356 0x0011a456 but 'fred + 0x123456' = 0x0012a456
358 Note that if the 15th bit was set in the value stored in the LO16
359 reloc, then we do not have to do anything:
361 movhi hi( fred + 0x10ffff ), r0, r1
362 movea lo( fred + 0x10ffff ), r1, r1
364 HI16S: 0x0011 + (0x00007000 >> 16) = 0x11
365 LO16: 0xffff + (0x00007000 & 0xffff) = 0x6fff
370 0x00116fff = fred + 0x10ffff = 0x7000 + 0x10ffff
372 Overflow can also occur if the computation carries into the 16th bit
373 and it also results in the 15th bit having the same value as the 15th
374 bit of the original value. What happens is that the HI16S reloc
375 will have already examined the 15th bit of the original value and
376 added 1 to the high part if the bit is set. This compensates for the
377 sign extension of 15th bit of the result of the computation. But now
378 there is a carry into the 16th bit, and this has not been allowed for.
380 So, for example if fred is at address 0xf000:
382 movhi hi( fred + 0xffff ), r0, r1 [bit 15 of the offset is set]
383 movea lo( fred + 0xffff ), r1, r1
385 HI16S: 0x0001 + (0x0000f000 >> 16) = 0x0001
386 LO16: 0xffff + (0x0000f000 & 0xffff) = 0xefff (carry into bit 16 is lost)
391 0x0000efff but 'fred + 0xffff' = 0x0001efff
393 Similarly, if the 15th bit remains clear, but overflow occurs into
394 the 16th bit then (assuming the address of fred is 0xf000):
396 movhi hi( fred + 0x7000 ), r0, r1 [bit 15 of the offset is clear]
397 movea lo( fred + 0x7000 ), r1, r1
399 HI16S: 0x0000 + (0x0000f000 >> 16) = 0x0000
400 LO16: 0x7000 + (0x0000f000 & 0xffff) = 0x6fff (carry into bit 16 is lost)
405 0x00006fff but 'fred + 0x7000' = 0x00016fff
407 Note - there is no need to change anything if a carry occurs, and the
408 15th bit changes its value from being set to being clear, as the HI16S
409 reloc will have already added in 1 to the high part for us:
411 movhi hi( fred + 0xffff ), r0, r1 [bit 15 of the offset is set]
412 movea lo( fred + 0xffff ), r1, r1
414 HI16S: 0x0001 + (0x00007000 >> 16)
415 LO16: 0xffff + (0x00007000 & 0xffff) = 0x6fff (carry into bit 16 is lost)
418 + 0x00006fff (bit 15 not set, so the top half is zero)
420 0x00016fff which is right (assuming that fred is at 0x7000)
422 but if the 15th bit goes from being clear to being set, then we must
423 once again handle overflow:
425 movhi hi( fred + 0x7000 ), r0, r1 [bit 15 of the offset is clear]
426 movea lo( fred + 0x7000 ), r1, r1
428 HI16S: 0x0000 + (0x0000ffff >> 16)
429 LO16: 0x7000 + (0x0000ffff & 0xffff) = 0x6fff (carry into bit 16)
432 + 0x00006fff (bit 15 not set, so the top half is zero)
434 0x00006fff which is wrong (assuming that fred is at 0xffff). */
