8988:6c2dc56e73b3 # Bug 256: enable vectorization with unaligned loads/stores.
9148:b8b8c421e36c # Relax mixing-type constraints for binary coefficient-wise operators
9174:d228bc282ac9 # merge
9175:abc7a3600098 # Include the cost of stores in unrolling
9212:c90098affa7b # Fix performance regression introduced in changeset 8aad8f35c955
9213:9f1c14e4694b # Fix performance regression in dgemm introduced by changeset 81d53c711775
9361:69d418c06999 # 3.3-beta2
9445:f27ff0ad77a3 # Optimize expression matching "d?=a-b*c" as "d?=a; d?=b*c;"
9583:bef509908b9d # 3.3-rc1
9593:2f24280cf59a # Bug 1311: fix alignment logic in some cases of (scalar*small).lazyProduct(small)
9722:040d861b88b5 # Disabled part of the matrix matrix peeling code that's incompatible with 512 bit registers
9792:26667be4f70b # 3.3.0
9891:41260bdfc23b # Fix a performance regression in (mat*mat)*vec for which mat*mat was evaluated multiple times.
9942:b1d3eba60130 # Operators += and -= do not resize!
9943:79bb9887afd4 # Ease compiler job to generate clean and efficient code in mat*vec
9946:2213991340ea # Complete rewrite of column-major-matrix * vector product to deliver higher performance of modern CPU.
9955:630471c3298c # Improve performance of row-major-dense-matrix * vector products for recent CPUs. (this is the next changeset fixing a typo)
9975:2eeed9de710c # Revert vec/y to vec*(1/y) in row-major TRSM
10442:e3f17da72a40 # Bug 1435: fix aliasing issue in exressions like: A = C - B*A;
10735:6913f0cf7d06 # Adds missing EIGEN_STRONG_INLINE to support MSVC properly inlining small vector calculations
10943:4db388d946bd # Bug 1562: optimize evaluation of small products of the form s*A*B by rewriting them as: s*(A.lazyProduct(B)) to save a costly temporary. Measured speedup from 2x to 5x.
10961:5007ff66c9f6 # Introduce the macro ei_declare_local_nested_eval to help allocating on the stack local temporaries via alloca, and let outer-products makes a good use of it.
