From 64711f9a47d4defa90417f5e8db8ed0060bc3275 Mon Sep 17 00:00:00 2001 From: Max Filippov Date: Wed, 19 Dec 2018 19:48:37 -0800 Subject: xtensa: implement jump_label support Use 3-byte 'nop' and 'j' instructions that are always present. Don't let assembler mark a spot right after patchable 'j' instruction as unreachable and later put literals or padding bytes there. Add separate implementations of patch_text for SMP and UP cases, avoiding use of atomics on UP.
