New Revision: 287295
URL: http://llvm.org/viewvc/llvm-project?rev=287295&view=rev
Log:
Add doxygen comments to fxsrintrin.h's intrinsics.
The doxygen comments are automatically generated based on Sony's intrinsics
document.
I got an OK from Eric Christopher to commit doxygen comments without prior code
review upstream. This patch was internally reviewed by Paul Robinson and
Charles Li.
