From 6ab11ac25bb987642d5ca1a07f4bd5f30c66c9c5 Mon Sep 17 00:00:00 2001 From: Khem Raj Date: Mon, 4 Feb 2019 16:36:26 -0800 Subject: multilib_header_wrapper.h: Use #pragma once Avoid infinite include loops, especially with bits/wordsize.h which is now possible with the synthesized headers since we now also synthesize bits/wordsize.h itelf for some arches e.g. arm/aarch64 In cases where extra preprocessing tools are used such as clang-tidy e.g. and these tools are not passed the knowledge about architecture then case comes where we enter into header include loop for bits/wordsize.h, since this template does explicitly include bits/wordsize.h To fix this emits the pragma once at beginning of file, this is better solution than include guards, and pragma once is practically supported on all compilers except few e.g. cray c/c++ compiler Signed-off-by: Khem Raj Signed-off-by: Richard Purdie --- scripts/multilib_header_wrapper.h | 1 + 1 file changed, 1 insertion(+) diff --git a/scripts/multilib_header_wrapper.h b/scripts/multilib_header_wrapper.h index 9660225fdd..4824790783 100644 --- a/scripts/multilib_header_wrapper.h +++ b/scripts/multilib_header_wrapper.h @@ -21,6 +21,7 @@ * */ +#pragma once #if defined (__bpf__) #define __MHWORDSIZE 64 -- cgit 1.2.3-korg
