Summary

  1. [CaptureTracking] Don't let comparisons against null escape inbounds pointers Pointers that are in-bounds (either through dereferenceable_or_null or thorough a getelementptr inbounds) cannot be captured with a comparison against null. There is no way to construct a pointer that is still in bounds but also NULL. This helps safe languages that insert null checks before load/store instructions. Without this patch, almost all pointers would be considered captured even for simple loads. With this patch, an icmp with null will not be seen as escaping as long as certain conditions are met. There was a lot of discussion about this patch. See the Phabricator thread for detals. Differential Revision: https://reviews.llvm.org/D60047

[CaptureTracking] Don't let comparisons against null escape inbounds pointers

Pointers that are in-bounds (either through dereferenceable_or_null or
thorough a getelementptr inbounds) cannot be captured with a comparison
against null. There is no way to construct a pointer that is still in
bounds but also NULL.

This helps safe languages that insert null checks before load/store
instructions. Without this patch, almost all pointers would be
considered captured even for simple loads. With this patch, an icmp with
null will not be seen as escaping as long as certain conditions are met.

There was a lot of discussion about this patch. See the Phabricator
thread for detals.
