[llvm-dev] Heroic LLVM optimizations

[Das, Dibyendu via llvm-dev]

Hi Tobias-

The loop fusion you mention is the one in libquantum/cpu2006 ? Or something else in cpu2017 ?

-Thx
Dibyendu

Hi Jose,

we have work based on Polly which should get the loop-fusion in SPEC2017. The code is not yet ready to share, but I would be interested to learn if this would be of use to you.

Best,
Tobias
