From 41fe06f89f96c5f9599855a2778c8a3dd7efe22d Mon Sep 17 00:00:00 2001 From: Andrew Pinski Date: Wed, 22 Jan 2020 23:34:34 +0000 Subject: [PATCH] Fix patchable-function-entry on arc The problem here is arc looks at current_output_insn unconditional but sometimes current_output_insn is NULL. With patchable-function-entry, it will be. This is similar to how the nios2, handles "%.". Committed as obvious after a simple test with -fpatchable-function-entry=1.
