New Revision: 265844
URL: http://llvm.org/viewvc/llvm-project?rev=265844&view=rev
Log:
Add doxygen comments to emmintrin.h's intrinsics. Only around 25% of the intrinsics in this file are documented now. The patches for the rest of the intrisics in this file will be send out later.
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.
