This file defines the accepted values for -mcpu=<CPU> 32 option. 33 34 Before including this file, define a macro: 35 36 ARC_CPU (NAME, ARCH, FLAGS, TUNE) 37 38 where the arguments are the fields of arc_cpu_t: 39 40 NAME A given arbitrary name. 41 ARCH Base architecture for the given CPU. 42 FLAGS Specific hardware flags that are enabled by this CPU configuration, 43 as defined in arc-options.def file, and allowed by arc-arches.def 44 file. The specific hardware flags are enumerated without using 45 spaces between the '|' character and consequtive flags. 46 EXTRA Extra hardware flags, different than the ones in 47 arc-arches.def. Here we can specify the width of lp_count, 48 for example. 49 TUNE Tune value for the given configuration, otherwise NONE. */ 50 51 ARC_CPU (em, em, 0, NONE, NONE) 52 ARC_CPU (em_mini, em, FL_RF16, NONE, NONE) 53 ARC_CPU (arcem, em, FL_MPYOPT_2|FL_CD|FL_BS, NONE, NONE) 54 ARC_CPU (em4, em, FL_CD, NONE, NONE) 55 ARC_CPU (em4_dmips, em, FL_MPYOPT_2|FL_CD|FL_DIVREM|FL_NORM|FL_SWAP|FL_BS, NONE, NONE) 56 ARC_CPU (em4_fpus, em, FL_MPYOPT_2|FL_CD|FL_DIVREM|FL_NORM|FL_SWAP|FL_BS|FL_FPU_FPUS, NONE, NONE) 57 ARC_CPU (em4_fpuda, em, FL_MPYOPT_2|FL_CD|FL_DIVREM|FL_NORM|FL_SWAP|FL_BS|FL_FPU_FPUDA, NONE, NONE) 58 ARC_CPU (quarkse_em, em, FL_MPYOPT_3|FL_CD|FL_DIVREM|FL_NORM|FL_SWAP|FL_BS|FL_FPX_QUARK|FL_SPFP|FL_DPFP, LPCOUNT_16, NONE) 59 60 ARC_CPU (hs, hs, 0, NONE, NONE) 61 ARC_CPU (archs, hs, FL_MPYOPT_2|FL_DIVREM|FL_LL64, NONE, NONE) 62 ARC_CPU (hs34, hs, FL_MPYOPT_2, NONE, NONE) 63 ARC_CPU (hs38, hs, FL_MPYOPT_9|FL_DIVREM|FL_LL64, NONE, NONE) 64 ARC_CPU (hs38_linux, hs, FL_MPYOPT_9|FL_DIVREM|FL_LL64|FL_FPU_FPUD_ALL, NONE, NONE) 65 ARC_CPU (hs4x, hs, FL_MPYOPT_9|FL_DIVREM|FL_LL64, NONE, ARCHS4X) 66 ARC_CPU (hs4xd, hs, FL_MPYOPT_9|FL_DIVREM|FL_LL64, NONE, ARCHS4XD) 67 68 ARC_CPU (arc600, 6xx, FL_BS, NONE, ARC600) 69 ARC_CPU (arc600_norm, 6xx, FL_BS|FL_NORM, NONE, ARC600) 70 ARC_CPU (arc600_mul64, 6xx, FL_BS|FL_NORM|FL_MUL64, NONE, ARC600) 71 ARC_CPU (arc600_mul32x16, 6xx, FL_BS|FL_NORM|FL_MUL32x16, NONE, ARC600) 72 ARC_CPU (arc601, 6xx, 0, NONE, ARC600) 73 ARC_CPU (arc601_norm, 6xx, FL_NORM, NONE, ARC600) 74 ARC_CPU (arc601_mul64, 6xx, FL_NORM|FL_MUL64, NONE, ARC600) 75 ARC_CPU (arc601_mul32x16, 6xx, FL_NORM|FL_MUL32x16, NONE, ARC600) 76 77 ARC_CPU (arc700, 700, 0, NONE, ARC700_4_2_STD) 78 ARC_CPU (nps400, 700, 0, NONE, ARC700_4_2_STD) 79 80 /* Local Variables: */ 81 /* mode: c */ 82 /* End: */ 83
