For 306 the divisor, we test early on that it is not 'negative'. 307 - divaw can't corrrectly process a divident that is larger than the divisor. 308 We handle this be checking that the divident prior to normalization is 309 not larger than the normalized divisor. As we then already know then 310 that the divisor fits 31 bit, this check also makes sure that the 311 divident fits. 312 - ordinary normalization of the divident could make it larger than the 313 normalized divisor, which again would be unsuitable for divaw. 314 Thus, we want to shift left the divident by one less, except that we 315 want to leave it alone if it is already 31 bit. To this end, we 316 double the input to norm with adds. 317 - If the divident has less bits than the divisor, that would leave us 318 with a negative number of divaw to execute. Although we could use a 319 conditional loop to avoid excess divaw, and then the quotient could 320 be extracted correctly as there'd be more than enough zero bits, the 321 remainder would be shifted left too far, requiring a conditional shift 322 right. The cost of that shift and the possible mispredict on the 323 conditional loop cost as much as putting in an early check for a zero 324 result. */ 325 bmsk r3,r0,29 326 brne.d r3,r0,.Large_dividend 327 norm.f r2,r1 328 brlo r0,r1,.Lret0 329 norm r3,r0 330 asl_s r1,r1,r2 331 sub_s r3,r3,1 332 asl_l r0,r0,r3 ; not short to keep loop aligned 333 sub lp_count,r2,r3 334 lp .Ldiv_end 335 divaw r0,r0,r1 336 .Ldiv_end:sub_s r3,r2,1 337 lsr r1,r0,r2 338 j_s.d [blink] 339 bmsk r0,r0,r3 340 341 .balign 4 342 .Large_dividend: 343 bmi .Ltrivial 344 asl_s r1,r1,r2 345 mov_s r3,0 346 sub1.f r4,r0,r1 347 mov.lo r4,r0 348 mov.hs r3,2 349 cmp r4,r1 350 sub.hs r4,r4,r1 351 add.hs r3,r3,1 352 mov.f lp_count,r2 353 lpne .Ldiv_end2 354 divaw r4,r4,r1 355 .Ldiv_end2:asl r0,r3,r2 356 lsr r1,r4,r2 357 sub_s r2,r2,1 358 bmsk r4,r4,r2 359 j_s.d [blink] 360 or.ne r0,r0,r4 361 362 .Lret0: 363 mov_s r1,r0 364 j_s.d [blink] 365 mov_l r0,0 366 .balign 4 367 .Ltrivial: 368 sub.f r1,r0,r1 369 mov.c r1,r0 370 mov_s r0,1 371 j_s.d [blink] 372 mov.c r0,0 373 #elif !defined (__OPTIMIZE_SIZE__) && !defined (__ARC_RF16__) 374 #if defined (__ARC_NORM__) && defined (__ARC_BARREL_SHIFTER__) 375 lsr_s r2,r0 376 brhs.d r1,r2,.Lret0_3 377 norm r2,r2 378 norm r3,r1 379 sub_s r3,r3,r2 380 asl_s r1,r1,r3 381 sub1.f 0,r0,r1 382 lsr.cs r1,r1,1 383 sbc r2,r3,0 384 sub1 r0,r0,r1 385 cmp_s r0,r1 386 mov.f lp_count,r2 387 #else /* ! __ARC_NORM__ */ 388 lsr_s r2,r0 389 brhs.d r1,r2,.Lret0_3 390 mov lp_count,32 391 .Lloop1: 392 asl_s r1,r1 ; den <<= 1 393 brls.d r1,r2,@.Lloop1 394 sub lp_count,lp_count,1 395 sub_s r0,r0,r1 396 lsr_s r1,r1 397 cmp_s r0,r1 398 xor.f r2,lp_count,31 399 #if !defined (__ARCEM__) && !defined (__ARCHS__) 400 mov_s lp_count,r2 401 #else 402 mov lp_count,r2 403 nop_s 404 #endif /* !__ARCEM__ && !__ARCHS__ */ 405 #endif /* !__ARC_NORM__ */ 406 sub.cc r0,r0,r1 407 mov_s r3,3 408 sbc r3,r3,0 409 #if defined (__ARC_BARREL_SHIFTER__) 410 asl_s r3,r3,r2 411 rsub r1,r1,1 412 lpne @.Lloop2_end 413 add1.f r0,r1,r0 414 sub.cc r0,r0,r1 415 .Lloop2_end: 416 lsr r1,r0,r2 417 #else 418 rsub r1,r1,1 419 lpne @.Lloop2_end 420 asl_s r3,r3 421 add1.f r0,r1,r0 422 sub.cc r0,r0,r1 423 .Lloop2_end: 424 lsr_s r1,r0 425 lsr.f lp_count,r2 426 mov.cc r1,r0 427 lpnz 1f 428 lsr_s r1,r1 429 lsr_s r1,r1 430 1: 431 #endif 432 bmsk r0,r0,r2 433 bclr r0,r0,r2 434 j_s.d [blink] 435 or_s r0,r0,r3 436 .Lret0_3: 437 #if 0 /* Slightly shorter, but slower. */ 438 lp .Loop3_end 439 brhi.d r1,r0,.Loop3_end 440 sub_s r0,r0,r1 441 .Loop3_end 442 add_s r1,r1,r0 443 j_s.d [blink] 444 rsub r0,lp_count,32-1 445 #else 446 mov_s r4,r1 447 sub.f r1,r0,r1 448 sbc r0,r0,r0 449 sub.cc.f r1,r1,r4 450 sbc r0,r0,0 451 sub.cc.f r1,r1,r4 452 sbc r0,r0,-3 453 j_s.d [blink] 454 add.cs r1,r1,r4 455 #endif 456 #else /* Arctangent-A5 */ 457 breq_s r1,0,@.Ldivmodend 458 mov_s r2,1 ; bit = 1 459 mov_s r3,0 ; res = 0 460 .Lloop1: 461 brhs r1,r0,@.Lloop2 462 bbit1 r1,31,@.Lloop2 463 asl_s r1,r1 ; den <<= 1 464 b.d @.Lloop1 465 asl_s r2,r2 ; bit <<= 1 466 .Lloop2: 467 brlo r0,r1,@.Lshiftdown 468 sub_s r0,r0,r1 ; num -= den 469 or_s r3,r3,r2 ; res |= bit 470 .Lshiftdown: 471 lsr_s r2,r2 ; bit >>= 1 472 lsr_s r1,r1 ; den >>= 1 473 brne_s r2,0,@.Lloop2 474 .Ldivmodend: 475 mov_s r1,r0 ; r1 = mod 476 j.d [blink] 477 mov_s r0,r3 ; r0 = res 478 /******************************************************/ 479 #endif 480 ENDFUNC(__udivmodsi4) 481 482 #endif 483 484 #ifdef L_udivsi3 485 .section .text 486 .align 4 487 488 .global SYM(__udivsi3) 489 FUNC(__udivsi3) 490 SYM(__udivsi3): 491 b @SYM(__udivmodsi4) 492 ENDFUNC(__udivsi3) 493 #if 0 /* interferes with linux loader */ 494 .section .__arc_profile_forward, "a" 495 .long SYM(__udivsi3) 496 .long SYM(__udivmodsi4) 497 .long 65536 498 #endif 499 500 #endif /* L_udivsi3 */ 501 502 #ifdef L_divsi3 503 .section .text 504 .align 4 505 506 .global SYM(__divsi3) 507 FUNC(__divsi3) 508 509 #ifndef __ARC_EA__ 510 SYM(__divsi3): 511 /* A5 / ARC60? */ 512 mov r12,blink 513 xor r11,r0,r1 514 abs_s r0,r0 515 bl.d @SYM(__udivmodsi4) 516 abs_s r1,r1 517 tst r11,r11 518 j.d [r12] 519 neg.mi r0,r0 520 #else /* !ifndef __ARC_EA__ */ 521 ;; We can use the abs, norm, divaw and mpy instructions for ARC700 522 #define MULDIV 523 #ifdef MULDIV 524 /* This table has been generated by divtab-arc700.c. */ 525 /* 1/512 .. 1/256, normalized.
