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 <raj.k...@gmail.com> --- V2: - No Changes, just rebased V3: - Do it using pragma once instead 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 -- 2.20.1 -- _______________________________________________ Openembedded-core mailing list Openembedded-core@lists.openembedded.org http://lists.openembedded.org/mailman/listinfo/openembedded-core
