[llvm-dev] Loop fusion in llvm polly

[Raja Patra via llvm-dev]

Hi all,

We are trying for loop fusion on nested loops. Firstly trying with -mllvm
-polly-opt-fusion=max and simple -mllvm -polly flag, is this the way to do
loop fusion in polly or some other flags or pragmas are available for loop
transformation from polly side. Please guide.

Also point to note that the nested loops have vector intrinsics and there
are non affine expressions.

Thanks,
Raja
