It is 43C probably hard to save more that an odd cycle there. The nc code is much 44C cruder (since tune/speed doesn't have any applicable direct measurements). 45C * Without the nc entry points, this becomes around 1800 bytes of object 46C code; the nc code adds over 1000 bytes. We should perhaps sacrifice a 47C few cycles for the non-nc code and let it fall into the nc code. 48 49C INPUT PARAMETERS 50define(`rp', `r32') 51define(`up', `r33') 52define(`vp', `r34') 53define(`n', `r35') 54define(`cy', `r36') 55 56ifdef(`OPERATION_add_n',` 57 define(ADDSUB, add) 58 define(CND, ltu) 59 define(INCR, 1) 60 define(LIM, -1) 61 define(LIM2, 0) 62 define(func, mpn_add_n) 63 define(func_nc, mpn_add_nc) 64') 65ifdef(`OPERATION_sub_n',` 66 define(ADDSUB, sub) 67 define(CND, gtu) 68 define(INCR, -1) 69 define(LIM, 0) 70 define(LIM2, -1) 71 define(func, mpn_sub_n) 72 define(func_nc, mpn_sub_nc) 73') 74 75define(PFDIST, 500) 76 77C Some useful aliases for registers we use 78define(`u0',`r14') define(`u1',`r15') define(`u2',`r16') define(`u3',`r17') 79define(`v0',`r24') define(`v1',`r25') define(`v2',`r26') define(`v3',`r27') 80define(`w0',`r28') define(`w1',`r29') define(`w2',`r30') define(`w3',`r31') 81define(`rpx',`r3') 82define(`upadv',`r20') define(`vpadv',`r21') 83 84MULFUNC_PROLOGUE(mpn_add_n mpn_add_nc mpn_sub_n mpn_sub_nc) 85 86ASM_START() 87PROLOGUE(func_nc) 88 .prologue 89 .save ar.lc, r2 90 .body 91ifdef(`HAVE_ABI_32',` 92 addp4 rp = 0, rp C M I 93 addp4 up = 0, up C M I 94 nop.i 0 95 addp4 vp = 0, vp C M I 96 nop.m 0 97 zxt4 n = n C I 98 ;;
