Davide Italiano	16a426e9a9	[LoopUnroll] Make the test for PR33437 actually useful. I forgot to specify -unroll-loop-peel, making this test not really effective. While here, adjust some details (naming and run line). Thanks to Sanjoy and Michael Z. for pointing out in their post-commit reviews. llvm-svn: 312015	2017-08-29 17:24:09 +00:00
Davide Italiano	20cb7e887f	[LoopUnroll] Properly update loop structure in case of successful peeling. When peeling kicks in, it updates the loop preheader. Later, a successful full unroll of the loop needs to update a PHI which i-th argument comes from the loop preheader, so it'd better look at the correct block. Fixes PR33437.

[LoopUnroll] Make the test for PR33437 actually useful.

I forgot to specify -unroll-loop-peel, making this test not
really effective. While here, adjust some details (naming and
run line). Thanks to Sanjoy and Michael Z. for pointing out in

[LoopUnroll] Properly update loop structure in case of successful peeling.

When peeling kicks in, it updates the loop preheader.
Later, a successful full unroll of the loop needs to update a PHI
which i-th argument comes from the loop preheader, so it'd better look
at the correct block. Fixes PR33437.
