[BUG] In cute/tensor_impl.hpp, delay creating new_layout to avoid unused-but-set-variable? #2487
Description
Which component has the problem?
CUTLASS C++
Bug Report
Describe the bug
We saw a build error because
include/cute/tensor_impl.hpp:765:6: error: variable ‘new_layout’ set but not used [-Werror=unused-but-set-variable]
pytorch/pytorch#158854
cc @Skylion007
I think it is because new_layout is not always used.
cutlass/include/cute/tensor_impl.hpp
Lines 765 to 768 in 6c0c8b7
Can this be fixed?
Steps/Code to reproduce bug
See PyTorch PR linked.
Expected behavior
Build should be successful even with -Werror=unused-but-set-variable
