288d456c29 Replace language_support module with builtin CheckLanguage 
The workaround_9220 function was introduced a long time ago to
workaround a CMake issue with enable_language(OPTIONAL). Since then
CMake has clarified that the OPTIONAL keywords has not been
implemented[0].

A CheckLanguage module is now provided with CMake to check if a language
can be enabled. Use that instead.

6fb3e5f176 STYLE: Remove CMake-language block-end command arguments 
Ancient versions of CMake required else(), endif(), and similar block
termination commands to have arguments matching the command starting the block.
This is no longer the preferred style.

4270c62812 Split the implementation of i?amax/min into two. Based on PR-627 by Sameer Agarwal. 
Like the Netlib reference implementation, I*AMAX now uses the L1-norm instead of the L2-norm for each element. Changed I*MIN accordingly.

c181dfb8ab Consistently use EIGEN_BLAS_FUNC in BLAS. 
Previously, for a few functions, eithe BLASFUNC or, EIGEN_CAT
was being used. This change uses EIGEN_BLAS_FUNC consistently
everywhere.

Also introduce EIGEN_BLAS_FUNC_SUFFIX, which by default is
equal to "_", this allows the user to inject a new suffix as
needed.

66e99ab6a1 Relax mixing-type constraints for binary coefficient-wise operators: 
- Replace internal::scalar_product_traits<A,B> by Eigen::ScalarBinaryOpTraits<A,B,OP>
- Remove the "functor_is_product_like" helper (was pretty ugly)
- Currently, OP is not used, but it is available to the user for fine grained tuning
- Currently, only the following operators have been generalized: *,/,+,-,=,*=,/=,+=,-=
- TODO: generalize all other binray operators (comparisons,pow,etc.)
- TODO: handle "scalar op array" operators (currently only * is handled)
- TODO: move the handling of the "void" scalar type to ScalarBinaryOpTraits

1f48f47ab7 Implement stricter argument checking for SYRK and SY2K and real matrices. To implement the BLAS API they should return info=2 if op='C' is passed for a complex matrix. Without this change, the Eigen BLAS fails the strict zblat3 and cblat3 tests in LAPACK 3.5. 2016-04-27 19:59:44 +02:00

80cae358b0 Adds a modified f2c-generated C implmentation for BLAS. 
This adds an optional implementation for the BLAS library that does
not require the use of a FORTRAN compiler. It can be enabled with
EIGEN_USE_F2C_BLAS.

The C implementation uses the standard gfortran calling convention
and does not require the use of -ff2c when compiled with gfortran.
