pankso@3435 | 10 * The first part of "struct _fpstate" is just the normal i387 |
pankso@3435 | 11 * hardware setup, the extra "status" word is used to save the |
pankso@3435 | 12 * coprocessor status word before entering the handler. |
pankso@3435 | 13 * |
pankso@3435 | 14 * Pentium III FXSR, SSE support |
pankso@3435 | 15 * Gareth Hughes <gareth@valinux.com>, May 2000 |
pankso@3435 | 16 * |
pankso@3435 | 17 * The FPU state data structure has had to grow to accommodate the |
pankso@3435 | 18 * extended FPU state required by the Streaming SIMD Extensions. |
pankso@3435 | 19 * There is no documented standard to accomplish this at the moment. |
