Add c10::irange to ExecuTorch#8554
Conversation
irange is a header-only utility that is both more readable than the usual way to write for loops and also solves -Wsign-compare issues. I've previously vetted that it generates the same assembly as a regular for loop. Differential Revision: [D69817195](https://our.internmc.facebook.com/intern/diff/D69817195/) [ghstack-poisoned]

is irange.h not part of headers from pytorch? or we decided that is not worth sharing?

it is a pytorch header, but it is used in executorch core. therefore it must be copied over just like everything else in runtime/core/portable_type/c10/c10 to keep the build hermetic for embedded users

Fix the copy right in line with rest of the codebase?

can you add a comment
no. the file should be identical to the version in pytorch core.

does it need <algorithm>?

not relevant; this is a direct copy from pytorch core.

not related to this diff per se, but makes me curious why we need in this file too.

No. this is coming directly from pytorch core. https://github.com/pytorch/pytorch/blob/main/c10/util/irange.h
