KNL Vectorization with larger vector width
...rn 65536;
here i changed 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 &...

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.

KNL Vectorization with larger vector width
...am unable
to debug this. each time i debug it, it returns me vectorized IR in gdb.
My goal is simple when i mention my target name in opt it should vectorize
by keeping the vector width= highest supported by my target which is 2048.
So $ opt -O3 -mytarget 1.ll -o 1_opt.ll
1_opt.ll should emit <2048xi32>,
<1024xi32>.........................<32xi32> etc.
How to achieve this? Please help.
Thank You
Regards
