* bug #955 - Implement a rotating kernel alternative in the 3px4 gebp pathGravatar Benoit Jacob2015-02-18
| | | | | | | | This is substantially faster on ARM, where it's important to minimize the number of loads. This is specific to the case where all packet types are of size 4. I made my best attempt to minimize how dirty this is... opinions welcome. Eventually one could have a generic rotated kernel, but it would take some work to get there. Also, on sandy bridge, in my experience, it's not beneficial (even about 1% slower).

|/ | | | | | | | | | | | | | This is only a debugging/testing patch. It allows testing specific product blocking sizes, typically to study the impact on performance. Example usage: int testk, testm, testn; #define EIGEN_TEST_SPECIFIC_BLOCKING_SIZES #define EIGEN_TEST_SPECIFIC_BLOCKING_SIZE_K testk #define EIGEN_TEST_SPECIFIC_BLOCKING_SIZE_M testm #define EIGEN_TEST_SPECIFIC_BLOCKING_SIZE_N testn #include <Eigen/Core>

|\ | | | | | | | | | | | | | | | | | | | | | | bug #877, bug #572: Get rid of Index conversion warnings, summary of changes: - Introduce a global typedef Eigen::Index making Eigen::DenseIndex and AnyExpr<>::Index deprecated (default is std::ptrdiff_t). - Eigen::Index is used throughout the API to represent indices, offsets, and sizes. - Classes storing an array of indices uses the type StorageIndex to store them. This is a template parameter of the class. Default is int. - Methods that *explicitly* set or return an element of such an array take or return a StorageIndex type. In all other cases, the Index type is used.

| | | | | | | | | | | | - fix usage of Index (API) versus StorageIndex (when multiple indexes are stored) - use StorageIndex(val) when the input has already been check - use internal::convert_index<StorageIndex>(val) when val is potentially unsafe (directly comes from user input)
