From 3ef4f939c3b24cddcb917c2d8a3ea7a588deecab Mon Sep 17 00:00:00 2001 From: Cherry Mui Date: Tue, 12 Sep 2023 15:15:12 -0400 Subject: [PATCH] [release-branch.go1.21] cmd/link: force old Apple linker in plugin mode There are some bugs in Apple's new linker that causes plugins to be built incorrectly. And the bugs probably will not be fixed when Xcode 15 is released (some time soon). Force old Apple linker to work around. Updates #61229. For #62598.
