[reland] Slicing with backed should produce backed output when possible (#178899) by ColinPeppler · Pull Request #178899 · pytorch/pytorch

ColinPeppler · 2026-03-31T17:32:54Z

Summary:

Original PR: #175819

it got reverted internally (D98767572 )
i must reland as a new diff internal -> then export again (hence this diff)

Summary

x[0:s1] where x.size(0) = s0-1 should produce Min(s1, s0-1)
Before this PR, it would produce u0.
