| 3 | Description: Disable SSE2 code on i386 | |
| 4 | This patch is not complete. A high-graded solution may use automatic switching | |
| 5 | between SSE2 and C++ implementations based on the results of runtime checks. | |
| 6 | The webrtc code already provides for one of them inside its GetCPUInfo function. | |
| 7 | Bug-Debian: https://bugs.debian.org/892823 | |
