[PATCH] D93731: scudo: Support memory tagging in the secondary allocator.

[Peter Collingbourne via Phabricator via llvm-commits]

pcc added a comment.

The perf regression on Android appears to have been caused by an incorrect computation of BlockSize in the secondary allocator, which made its way into the statistics returned by mallinfo, which caused ART to enter a slow path. With this fixed I was unable to measure a regression.
