2386fc8528 Added support for 32bit index on a per tensor/tensor expression. This enables us to use 32bit indices to evaluate expressions on GPU faster while keeping the ability to use 64 bit indices to manipulate large tensors on CPU in the same binary. 2015-02-27 12:57:13 -08:00

97a36ecba4 Suppress some remaining Index conversion warnings 2015-02-17 18:52:39 +01:00
Gael Guennebaud
aa6c516ec1 Fix many long to int conversion warnings: 
- 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)
 2015-02-16 13:19:05 +01:00
Gael Guennebaud
fc202bab39 Index refactoring: StorageIndex must be used for storage only (and locally when it make sense). In all other cases use the global Index type. 2015-02-13 18:57:41 +01:00

Benoit Steiner
14f537c296 gcc doesn't consider that 
template<typename OtherDerived> TensorStridingOp& operator = (const OtherDerived& other)
provides a valid assignment operator for the striding operation, and therefore refuses to compile code like:
result.stride(foo) = source.stride(bar);

Added the explicit
   TensorStridingOp& operator = (const TensorStridingOp& other)

as a workaround to get the code to compile, and did the same in all the operations that can be used as lvalues.
