From 7757567358a84c3774cb972350bd7ea299daaa8d Mon Sep 17 00:00:00 2001 From: "Vladimir N. Makarov" Date: Fri, 10 Feb 2023 12:17:07 -0500 Subject: [PATCH] RA: Use caller save equivalent memory only for LRA Recently I submitted a patch to reuse memory with constant address for caller saves optimization for constant or pure function call. It seems to work only for targets using LRA instead of the old reload pass. So the patch switches off this optimization when the old reload pass is used.
