GCC supports SIMD operations on the SPARC using both the generic vector extensions (see Vector Extensions) as well as built-in functions for the SPARC Visual Instruction Set (VIS). When you use the -mvis switch, the VIS extension is exposed as the following built-in functions:
typedef int v1si __attribute__ ((vector_size (4))); typedef int v2si __attribute__ ((vector_size (8))); typedef short v4hi __attribute__ ((vector_size (8))); typedef short v2hi __attribute__ ((vector_size (4))); typedef unsigned char v8qi __attribute__ ((vector_size (8))); typedef unsigned char v4qi __attribute__ ((vector_size (4))); void __builtin_vis_write_gsr (int64_t); int64_t __builtin_vis_read_gsr (void); void * __builtin_vis_alignaddr (void *, long); void * __builtin_vis_alignaddrl (void *, long); int64_t __builtin_vis_faligndatadi (int64_t, int64_t); v2si __builtin_vis_faligndatav2si (v2si, v2si); v4hi __builtin_vis_faligndatav4hi (v4si, v4si); v8qi __builtin_vis_faligndatav8qi (v8qi, v8qi); v4hi __builtin_vis_fexpand (v4qi); v4hi __builtin_vis_fmul8x16 (v4qi, v4hi); v4hi __builtin_vis_fmul8x16au (v4qi, v2hi); v4hi __builtin_vis_fmul8x16al (v4qi, v2hi); v4hi __builtin_vis_fmul8sux16 (v8qi, v4hi); v4hi __builtin_vis_fmul8ulx16 (v8qi, v4hi); v2si __builtin_vis_fmuld8sux16 (v4qi, v2hi); v2si __builtin_vis_fmuld8ulx16 (v4qi, v2hi); v4qi __builtin_vis_fpack16 (v4hi); v8qi __builtin_vis_fpack32 (v2si, v8qi); v2hi __builtin_vis_fpackfix (v2si); v8qi __builtin_vis_fpmerge (v4qi, v4qi); int64_t __builtin_vis_pdist (v8qi, v8qi, int64_t); long __builtin_vis_edge8 (void *, void *); long __builtin_vis_edge8l (void *, void *); long __builtin_vis_edge16 (void *, void *); long __builtin_vis_edge16l (void *, void *); long __builtin_vis_edge32 (void *, void *); long __builtin_vis_edge32l (void *, void *); long __builtin_vis_fcmple16 (v4hi, v4hi); long __builtin_vis_fcmple32 (v2si, v2si); long __builtin_vis_fcmpne16 (v4hi, v4hi); long __builtin_vis_fcmpne32 (v2si, v2si); long __builtin_vis_fcmpgt16 (v4hi, v4hi); long __builtin_vis_fcmpgt32 (v2si, v2si); long __builtin_vis_fcmpeq16 (v4hi, v4hi); long __builtin_vis_fcmpeq32 (v2si, v2si); v4hi __builtin_vis_fpadd16 (v4hi, v4hi); v2hi __builtin_vis_fpadd16s (v2hi, v2hi); v2si __builtin_vis_fpadd32 (v2si, v2si); v1si __builtin_vis_fpadd32s (v1si, v1si); v4hi __builtin_vis_fpsub16 (v4hi, v4hi); v2hi __builtin_vis_fpsub16s (v2hi, v2hi); v2si __builtin_vis_fpsub32 (v2si, v2si); v1si __builtin_vis_fpsub32s (v1si, v1si); long __builtin_vis_array8 (long, long); long __builtin_vis_array16 (long, long); long __builtin_vis_array32 (long, long);
