Store the 301 operand value in *INSN and return true on success. 302 303 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: 307 308 movhi hi( fred ), r0, r1 309 movea lo( fred ), r1, r1 310 311 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: 313 314 movhi hi( fred + 0x123456 ), r0, r1 315 movea lo( fred + 0x123456 ), r1, r1 316 317 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 319 instructions were: 320 321 movhi hi( fred + 0x10ffff ), r0, r1 322 movea lo( fred + 0x10ffff ), r1, r1 323 324 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: 330 331 movhi hi( fred - 1 ), r0, r1 332 movea lo( fred - 1 ), r1, r1 333 334 then 0 is stored in the MOVHI instruction and -1 is stored in the 335 MOVEA instruction. 336 337 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: 343 344 movhi hi( fred + 0x123456 ), r0, r1 345 movea lo( fred + 0x123456 ), r1, r1 346 347 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: 350 351 HI16S: 0x0012 + (0x00007000 >> 16) = 0x12 352 LO16: 0x3456 + (0x00007000 & 0xffff) = 0xa456 353 354 but when the instructions are executed, the MOVEA instruction's value 355 is signed extended, so the sum becomes: 356 357 0x00120000 358 + 0xffffa456 359 ------------ 360 0x0011a456 but 'fred + 0x123456' = 0x0012a456 361 362 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: 364 365 movhi hi( fred + 0x10ffff ), r0, r1 366 movea lo( fred + 0x10ffff ), r1, r1 367 368 HI16S: 0x0011 + (0x00007000 >> 16) = 0x11 369 LO16: 0xffff + (0x00007000 & 0xffff) = 0x6fff 370 371 0x00110000 372 + 0x00006fff 373 ------------ 374 0x00116fff = fred + 0x10ffff = 0x7000 + 0x10ffff 375 376 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. 383 384 So, for example if fred is at address 0xf000: 385 386 movhi hi( fred + 0xffff ), r0, r1 [bit 15 of the offset is set] 387 movea lo( fred + 0xffff ), r1, r1 388 389 HI16S: 0x0001 + (0x0000f000 >> 16) = 0x0001 390 LO16: 0xffff + (0x0000f000 & 0xffff) = 0xefff (carry into bit 16 is lost) 391 392 0x00010000 393 + 0xffffefff 394 ------------ 395 0x0000efff but 'fred + 0xffff' = 0x0001efff 396 397 Similarly, if the 15th bit remains clear, but overflow occurs into 398 the 16th bit then (assuming the address of fred is 0xf000): 399 400 movhi hi( fred + 0x7000 ), r0, r1 [bit 15 of the offset is clear] 401 movea lo( fred + 0x7000 ), r1, r1 402 403 HI16S: 0x0000 + (0x0000f000 >> 16) = 0x0000 404 LO16: 0x7000 + (0x0000f000 & 0xffff) = 0x6fff (carry into bit 16 is lost) 405 406 0x00000000 407 + 0x00006fff 408 ------------ 409 0x00006fff but 'fred + 0x7000' = 0x00016fff 410 411 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: 414 415 movhi hi( fred + 0xffff ), r0, r1 [bit 15 of the offset is set] 416 movea lo( fred + 0xffff ), r1, r1 417 418 HI16S: 0x0001 + (0x00007000 >> 16) 419 LO16: 0xffff + (0x00007000 & 0xffff) = 0x6fff (carry into bit 16 is lost) 420 421 0x00010000 422 + 0x00006fff (bit 15 not set, so the top half is zero) 423 ------------ 424 0x00016fff which is right (assuming that fred is at 0x7000) 425 426 but if the 15th bit goes from being clear to being set, then we must 427 once again handle overflow: 428 429 movhi hi( fred + 0x7000 ), r0, r1 [bit 15 of the offset is clear] 430 movea lo( fred + 0x7000 ), r1, r1 431 432 HI16S: 0x0000 + (0x0000ffff >> 16) 433 LO16: 0x7000 + (0x0000ffff & 0xffff) = 0x6fff (carry into bit 16) 434 435 0x00000000 436 + 0x00006fff (bit 15 not set, so the top half is zero) 437 ------------ 438 0x00006fff which is wrong (assuming that fred is at 0xffff). */ 439 440 static bfd_boolean 441 v850_elf_perform_lo16_relocation (bfd *abfd, unsigned long *insn, 442 unsigned long addend) 443 { 444 #define BIT15_SET(x) ((x) & 0x8000) 445 #define OVERFLOWS(a,i) ((((a) & 0xffff) + (i)) > 0xffff) 446 447 if ((BIT15_SET (*insn + addend) && !
