From 6ef55060a1cc29dd54ff390f22cb3de266dab2b0 Mon Sep 17 00:00:00 2001 From: Heiko Carstens Date: Mon, 13 Mar 2023 13:50:35 +0100 Subject: s390: make use of CONFIG_FUNCTION_ALIGNMENT Make use of CONFIG_FUNCTION_ALIGNMENT which was introduced with commit d49a0626216b ("arch: Introduce CONFIG_FUNCTION_ALIGNMENT"). Select FUNCTION_ALIGNMENT_8B for gcc in order to reflect gcc's default function alignment. For all other compilers, which is only clang, select a function alignment of 16 bytes which reflects the default function alignment for clang. Also change the __ALIGN define to follow whatever the value of CONFIG_FUNCTION_ALIGNMENT is. This makes sure that the alignment of C and assembler functions is the same. In result everything still uses the default function alignment for both compilers. However in addition this is now also true for all assembly functions, so that all functions have a consistent alignment.
