From 5c63eb5d56abd4e5232add4727247965a863d851 Mon Sep 17 00:00:00 2001 From: Khem Raj Date: Sun, 15 Dec 2019 14:02:45 -0800 Subject: [PATCH] Do not add stack pointer to clobber list It was being ignored until now when gcc 9.0 became capable of flagging these silent ignore via [1]. We weren't actually clobbering the stack pointers here so it should not cause change in behavior.
