From 8d92e992a785f35d23f845206cf8c6cafbc264e0 Mon Sep 17 00:00:00 2001 From: Eugeniy Paltsev Date: Wed, 11 Mar 2020 19:26:43 +0300 Subject: [PATCH] ARC: define __ALIGN_STR and __ALIGN symbols for ARC The default defintions use fill pattern 0x90 for padding which for ARC generates unintended "ldh_s r12,[r0,0x20]" corresponding to opcode 0x9090 So use ".align 4" which insert a "nop_s" instruction instead.
