https://gcc.gnu.org/bugzilla/show_bug.cgi?id=100152 --- Comment #59 from CVS Commits --- The releases/gcc-10 branch has been updated by Iain D Sandoe : https://gcc.gnu.org/g:b6a762bf4645d495ea2218dbabcebd0c15eb60fc commit r10-10797-gb6a762bf4645d495ea2218dbabcebd0c15eb60fc Author: Iain Sandoe Date: Mon May 3 08:22:53 2021 +0100 Darwin, X86: Adjust call clobbers to allow for lazy-binding [PR 100152]. We allow public functions defined in a TU to bind locally for PIC code (the default) on 64bit Mach-O. If such functions are not inlined, we cannot tell at compile-time if they might be called via the lazy symbol resolver (this can depend on options given at link-time). Therefore, we must assume that the lazy resolver could be used which clobbers R11 and R10. Signed-off-by: Iain Sandoe gcc/ChangeLog: PR target/100152 * config/i386/i386-expand.c (ix86_expand_call): If a call is to a non-local-binding, or local but to a public symbol, then assume that it might be indirected via the lazy symbol binder. Mark R10 and R10 as clobbered in that case. (cherry picked from commit 41bd1b190358fce213f5add8396faf14a32d5c23)

Note the problem is present on closed branches too.
