From be2f5816b6cf6513591f825df1d0438729b83388 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Konstantin=20=C4=90or=C4=91evi=C4=87?= Date: Thu, 9 Apr 2020 01:18:30 +0200 Subject: Fix compile issues related to NO_ACTION_MACRO/FUNCTION and LTO_ENABLE (#8663) * Define NO_ACTION_MACRO/FUNCTION in header instead of makefile when LTO is enabled Currently, boards and keymaps that define NO_ACTION_MACRO/FUNCTION unconditionally will not compile with LTO_ENABLE (#8604). This fixes the issue by moving the definitions from common.mk to action.h, which enables us to check for previous definitions of those macros (this cannot be done in a makefile). * Remove LTO checks in templates Since now NO_ACTION_MACRO/FUNCTION are defined as needed in action.h (which is included by quantum.h), checking for LTO in keyboard and user code is no longer required. * Update LTO_ENABLE docs --- tmk_core/common/action.h | 10 ++++++++++ 1 file changed, 10 insertions(+) (limited to 'tmk_core/common/action.h') diff --git a/tmk_core/common/action.h b/tmk_core/common/action.h index dd22023f9b..c82c9c81be 100644 --- a/tmk_core/common/action.h +++ b/tmk_core/common/action.h @@ -28,6 +28,16 @@ along with this program.
