[PATCH] D128093: [lld-macho] Initial support for Linker Optimization Hints

[Daniel Bertalan via Phabricator via llvm-commits]

BertalanD updated this revision to Diff 438204.
BertalanD added a comment.

Pre-allocated the vector storing the parsed optimization hints. Changed `parsedRelocs` to be a sorted array instead of a `DenseMap`.  This decreased the runtime penalty to under 200 ms when linking Chromium on an M1 <https://reviews.llvm.org/M1> Mac mini. (Chromium has over 4 million LOHs!)
