7838fda82c Add a SparseCompressedBase class providing (un)compressed accessors (like data()/*Stride() for dense matrices), 
and a CompressedAccessBit flag (similar to DirectAccessBit for dense matrices).

5ef95fabee bug #936, patch 3/3: Properly detect FMA support on ARM (requires VFPv4) 
and use it instead of MLA when available, because it's both more accurate,
and faster.

0f21613698 bug #936, patch 2/3: Remove EIGEN_VECTORIZE_FMA, was redundant with EIGEN_HAS_SINGLE_INSTRUCTION_MADD 2015-01-30 17:44:26 -05:00

340b8afb14 bug #936, patch 1.5/3: rename _FUSED_ macros to _SINGLE_INSTRUCTION_, 
because this is what they are about. "Fused" means "no intermediate rounding
between the mul and the add, only one rounding at the end". Instead,
what we are concerned about here is whether a temporary register is needed,
i.e. whether the MUL and ADD are separate instructions.
Concretely, on ARM NEON, a single-instruction mul-add is always available: VMLA.
But a true fused mul-add is only available on VFPv4: VFMA.

759bd92a85 bug #935: Add asm comments in GEBP kernels to work around a bug 
in both GCC and Clang on ARM/NEON, whereby they spill registers,
severely harming performance. The reason why the asm comments
make a difference is that they prevent the compiler from
reordering code across these boundaries, which has the effect
of extending the lifetime of local variables and increasing
register pressure on this register-tight code.

Tim Murray
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.
