[llvm-dev] LoopVectorize - determine the bounds of the original loop

[Alex Susu via llvm-dev]

   Hello.
     Is there an easy way to obtain in the LoopVectorize module the upper and lower bounds 
of the loop being vectorized - I wasn't really able to find in the original code of 
LoopVectorize code calculating these bounds, although I know this module quite well and I 
am wondering if maybe they are already computed. (I put a similar question at 
http://lists.llvm.org/pipermail/llvm-dev/2016-August/103988.html ) .

     I have to admit I don't know well the ScalarEvolution class but I think I can also 
use ScalarEvolution's getUnsignedRangeMax() and getUnsignedRangeMin(), but these are newer 
methods added to ScalarEvolution in the last months and I normally work on an older LLVM 
trunk.

     Any help would be appreciated.

   Thank you,
     Alex
