From 44fa9c1080fe6a9539f0d2345b9d2ae37b8ee57a Mon Sep 17 00:00:00 2001 From: Wilco Dijkstra Date: Wed, 24 Jul 2024 15:17:47 +0100 Subject: math: Improve layout of expf data GCC aligns global data to 16 bytes if their size is >= 16 bytes. This patch changes the exp2f_data struct slightly so that the fields are better aligned. As a result on targets that support them, load-pair instructions accessing poly_scaled and invln2_scaled are now 16-byte aligned.
