[LLVMdev] Fwd: [Review Request][PATCH] Add the function "vectorizeBasicBlock"
...ly, but read from an instance of the VectorizeConfig class,
where the VectorizeConfig class is designed to provide the vectorize
related parameters to to the BBVectorize pas.
After this, people can pass target specific vectorize configuration to
the BBVectorize pass in tools like LLC. And original
createBBVectorizePass function can create a VectorizeConfig that read
the configuration from the commandline options and pass it to the
BBVectorizePass, hence users can still control the behaviour of the
pass with command like option.
Any comment or suggestion is appreciated.
best regards

[LLVMdev] [llvm-commits] [PATCH] BasicBlock Autovectorization Pass
Tobias, et al.,
Attached is the my autovectorization pass. I've fixed a bug that appears
when using -bb-vectorize-aligned-only, fixed some 80-col violations,
etc., and at least on x86_64, all test cases pass except for a few; and
all of these failures look like instruction-selection bugs. For example:

[LLVMdev] [llvm-commits] [PATCH] BasicBlock Autovectorization Pass
Tobias,
I've attached the latest version of my autovectorization patch. I was
able to add support for using the ScalarEvolution analysis for
load/store pairing (thanks for your help!). This led to a modest
performance increase and a modest compile-time increase. This version
also has a cutoff as you suggested (although the default value is set
high (4000 instructions between pairs) because
