dyung created this revision. This is the result of several patches we made internally to update the documentation that we would like to have reviewed for possible submission.
The changes include: 1. Fix incorrect wording in various intrinsic descriptions. Previously the descriptions used "low-order" and "high-order" when the intended meaning was "even-indexed" and "odd-indexed". These patches were made by Craig Flores https://reviews.llvm.org/D41518 Files: lib/Headers/pmmintrin.h Index: lib/Headers/pmmintrin.h =================================================================== --- lib/Headers/pmmintrin.h +++ lib/Headers/pmmintrin.h @@ -115,8 +115,8 @@ return __builtin_ia32_hsubps((__v4sf)__a, (__v4sf)__b); } -/// \brief Moves and duplicates high-order (odd-indexed) values from a 128-bit -/// vector of [4 x float] to float values stored in a 128-bit vector of +/// \brief Moves and duplicates odd-indexed values from a 128-bit vector +/// of [4 x float] to float values stored in a 128-bit vector of /// [4 x float]. /// /// \headerfile <x86intrin.h> @@ -137,7 +137,7 @@ return __builtin_shufflevector((__v4sf)__a, (__v4sf)__a, 1, 1, 3, 3); } -/// \brief Duplicates low-order (even-indexed) values from a 128-bit vector of +/// \brief Duplicates even-indexed values from a 128-bit vector of /// [4 x float] to float values stored in a 128-bit vector of [4 x float]. /// /// \headerfile <x86intrin.h>
