- This change in made in MAKE build system.
- Removed -fno-tree-loop-vectorize from global kernel flags,
instead added it to lpgemm specific kernels only.
- If this flag is not used , then gcc tries to auto
vectorize the code which results in usages of
vector registers, if the auto vectorized function
is using intrinsic then the total numbers of vector
registers used by intrinsic and auto vectorized
code becomes more than the registers
available in machine which causes read and writes
to stack, which is causing regression in lpgemm.
- If this flag is enabled globally, then the files which
do not use any intrinsic code do not get auto
vectorized.
- To get optimal performance for both blis and lpgemm,
this flag is enabled for lpgemm kernels only.
