KNL Vectorization with larger vector width
...anged 512 to 65536. Then in loopvectorize.cpp i did following;
assert(MaxVectorSize <= 2048 && "Did not expect to pack so many elements"
" into one vector!");
changed 64 to 2048.
It runs fine. I can see in IR <2048xi32> or <1024xi64> emission.
But I cannot see the vector mix like in default knl if iterations=15 we see
1<8xi32> and rest scalar. so here when i keep iteration=2047 i get all
scalar why is that so? similarly in polly as well i cant see vector mixes
like its happening for KNL it emits <v16i32>, <v...

KNL Vectorization with larger vector width
Thank You. I got it. Version issue.
TTI.getRegisterBitWidth(true)
How to put my target machine info in TTI?
Please help.
