From 33adb276fef9d2050c0c36a87ef3ed644cc3d531 Mon Sep 17 00:00:00 2001 From: Aaron Gokaslan Date: Sun, 19 Oct 2025 08:00:06 +0000 Subject: [PATCH] [BE][Ez]: Update Eigen to 5.0.0. C++14 support and more! (#165840) Update Eigen pin to 5.0.0 . Tons of new features and perf improvements. Most importantly updates minimum from C++03 to C++14 giving a ton of performance optimizations like properly implemented move operators, simplified code, etc. Also improved vectorization particularily on ARM. We really only use this library as a fallback for sparse operators, but still useful to update it.
