| |
| <p>GCC supports SIMD operations on the SPARC using both the generic vector |
| extensions (see <a href="Vector-Extensions.html#Vector-Extensions">Vector Extensions</a>) as well as built-in functions for |
| the SPARC Visual Instruction Set (VIS). When you use the <samp><span class="option">-mvis</span></samp> |
| switch, the VIS extension is exposed as the following built-in functions: |
| |
| <pre class="smallexample"> typedef int v2si __attribute__ ((vector_size (8))); |
| typedef short v4hi __attribute__ ((vector_size (8))); |
| typedef short v2hi __attribute__ ((vector_size (4))); |
| typedef char v8qi __attribute__ ((vector_size (8))); |
| typedef char v4qi __attribute__ ((vector_size (4))); |
| |
| void * __builtin_vis_alignaddr (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); |
